Why Async Result Storage Matters

Apache Superset is a powerful, open-source data visualisation platform, but it can become a bottleneck if you’re running large queries, exporting datasets, or serving concurrent dashboard requests across your organisation. The difference between a snappy, responsive analytics platform and one that times out or locks up often comes down to one critical decision: how you handle asynchronous query execution and where you store the results.

Async result storage is not optional in production. If you’re running Superset at any meaningful scale—more than 20 concurrent users, queries longer than 30 seconds, or dashboards with multiple heavy aggregations—synchronous query execution will fail. Users will hit timeouts. Dashboards will hang. Your data team will spend more time debugging than shipping.

The real cost is operational. When Superset queries block the web server, every concurrent request consumes a worker thread. A single slow query can exhaust your entire thread pool, making the entire platform unresponsive. Async execution decouples query processing from the HTTP request cycle, allowing Superset to remain responsive whilst queries run in the background. But async execution is only half the story. You also need a reliable, performant place to store query results.

At PADISO, we’ve tuned Superset deployments across financial services, retail, and government sectors in Australia and internationally. The teams that succeed move from synchronous to async quickly, choose the right result backend for their workload, and then instrument their systems to understand what’s actually happening. This guide captures the real patterns we apply on customer engagements.

Understanding Superset’s Async Architecture

How Superset Executes Queries

Superset has two execution modes: synchronous and asynchronous. In synchronous mode, the web server executes the query directly and waits for the result before responding to the client. This works fine for small dashboards and quick exploratory queries, but it doesn’t scale. A single slow query blocks the worker thread for the entire request duration.

Asynchronous execution inverts this model. When a query is submitted, Superset enqueues it to a task queue (usually Celery), immediately returns a task ID to the client, and lets a background worker process the query. The client polls for the result, or Superset can push results via WebSocket. The query runs independently of the HTTP request, and the web server remains free to serve other requests.

The async model is described in detail in the official Superset documentation on async queries via Celery. Understanding this flow is essential: request → task enqueue → web server responds immediately → background worker executes → result stored → client retrieves result from storage.

The Role of Result Backends

Once a query completes, the result must be stored somewhere. Superset doesn’t hold results in memory by default—it writes them to a result backend. This backend is typically Redis, a relational database, or a distributed cache. The choice of backend directly affects performance, reliability, and operational complexity.

Result backends serve several purposes. First, they decouple query execution from result retrieval. A user can submit a query, close their browser, and retrieve the result hours later (if the backend is durable). Second, they enable result caching. If two users run the same query within a short window, Superset can return the cached result instead of re-executing. Third, they provide visibility into query history and status.

The wrong choice here cascades into problems. If your result backend is too slow, users wait for results even though the query finished. If it’s unreliable, results disappear and users re-run queries. If it’s not durable, async queries become useless because results evaporate on restart.

Task Queue Architecture

Celery is Superset’s task queue of choice. Celery distributes work across multiple worker processes, each consuming tasks from a message broker (usually Redis or RabbitMQ). When Superset enqueues a query, Celery picks it up from the broker and executes it on an available worker.

The architecture is simple but critical: web server → message broker → workers → result backend. If any link in this chain is weak, performance suffers. A slow message broker means tasks queue up. Insufficient workers mean queries wait in the queue. A slow result backend means results take forever to write.

---

Configuring Celery and Result Backends

Step 1: Enable Async Queries in Superset

Start by enabling async queries in your Superset configuration. In superset_config.py, set:

ASYNC_QUERY_JOB_TIMEOUT = 3600  # 1 hour timeout
SUPERSET_CELERY_ENABLED = True
SUPERSET_CELERY_WORKERS = 4  # Start with workers equal to CPU cores

These settings tell Superset to route queries to Celery instead of executing them synchronously. The timeout defines how long a query can run before Celery kills it. Set this based on your workload—financial services often need 1–2 hours for heavy aggregations; media and retail may need only 10–30 minutes.

Step 2: Configure the Message Broker

Celery needs a message broker to communicate with workers. Redis is the most common choice for Superset deployments. Configure it in superset_config.py:

CELERY_BROKER_URL = "redis://redis-broker:6379/0"
CELERY_RESULT_BACKEND = "redis://redis-results:6379/1"

Note the separate databases: 0 for the broker, 1 for results. This isolation prevents a backlog of tasks from evicting cached results. If you’re running Redis in production, use a managed service like AWS ElastiCache or Azure Cache for Redis. Never run Redis on the same host as Superset in production—network isolation improves reliability.

For RabbitMQ, the configuration is similar:

CELERY_BROKER_URL = "amqp://user:password@rabbitmq:5672//"
CELERY_RESULT_BACKEND = "redis://redis-results:6379/1"

RabbitMQ is more reliable than Redis for message brokering (it persists to disk), but Redis is simpler to operate and sufficient for most Superset workloads if you can tolerate losing queued tasks on broker restart.

Step 3: Configure Result Backend Storage

The result backend is where query results live. Redis is the default, but you have options. Here’s a Redis configuration:

CELERY_RESULT_BACKEND = "redis://redis-results:6379/1"
CELERY_RESULT_BACKEND_TRANSPORT_OPTIONS = {
    "master_name": "mymaster",  # For Sentinel deployments
    "socket_connect_timeout": 5,
    "socket_timeout": 5,
    "retry_on_timeout": True,
}

The transport options are crucial. socket_connect_timeout and socket_timeout prevent Superset from hanging if Redis is slow or unreachable. retry_on_timeout tells Celery to retry the write, which helps during transient network issues. For production, use Redis Sentinel or Cluster to ensure high availability.

Alternatively, you can store results in a relational database. This is slower than Redis but more durable:

CELERY_RESULT_BACKEND = "db+postgresql://user:password@postgres:5432/superset_results"

Database backends are useful if you want results to survive a Redis restart, but they introduce latency. A typical Redis write is < 5ms; a database write is 10–50ms depending on network and disk. At scale, this adds up.

Step 4: Start Celery Workers

With Celery configured, start workers. In production, use a process manager like systemd or Supervisor:

celery -A superset.tasks worker --loglevel=info --concurrency=4 --pool=prefork

The --concurrency flag sets the number of concurrent tasks per worker process. For CPU-bound work (query execution), set this to the number of CPU cores. For I/O-bound work (network requests, database queries), you can increase it.

Run multiple worker processes on different hosts for redundancy. If one worker dies, others continue processing. Use Kubernetes or Docker to manage worker lifecycle.

---

Redis vs. Database Backends: Trade-offs

Redis: Speed and Simplicity

Redis is the default for good reason. It’s fast—sub-millisecond writes and reads—and simple to operate. Results are stored in memory and optionally persisted to disk. For most Superset deployments, Redis is the right choice.

The trade-off is durability. Redis is in-memory, so if it crashes, results are lost (unless you enable RDB persistence or AOF logging). For exploratory analytics, this is acceptable—users can re-run queries. For production reports, it’s risky.

To improve durability, enable Redis persistence:

# In redis.conf
save 900 1      # Save if 1 key changed in 900 seconds
save 300 10     # Save if 10 keys changed in 300 seconds
save 60 10000   # Save if 10,000 keys changed in 60 seconds
appendonly yes  # Enable AOF logging

With AOF, every write is logged to disk. On restart, Redis replays the log and recovers all results. The trade-off is I/O overhead—each write incurs a disk write. On modern SSDs, this is < 1ms additional latency, but it adds up under high concurrency.

Database Backends: Durability and Complexity

Storing results in PostgreSQL or MySQL is more durable but slower. Results survive restarts and can be queried directly for auditing. However, database writes are 10–50× slower than Redis, and you introduce another service to operate.

Database backends make sense if:

• You need audit trails of all query results (compliance requirement).
• You want results to survive infrastructure restarts.
• You’re already running a highly available database and want to consolidate.

For most startups and mid-market companies, Redis is sufficient. When you scale to enterprise (100+ concurrent users, thousands of daily queries), consider a hybrid approach: Redis for hot results (last 7 days) and a database for cold storage (archival).

Hybrid Approach: Redis + Database

Some teams implement a two-tier system. Hot results live in Redis for speed. After 7 days, results are archived to a database. This gives you speed for recent queries and durability for audit trails.

Implementing this requires custom logic, but it’s worth it at scale. Use a scheduled task to periodically scan Redis, identify old results, and write them to the database.

---

Production Tuning Patterns

Pattern 1: Right-Sizing Worker Concurrency

The number of concurrent workers directly affects query throughput. Too few, and queries queue up. Too many, and you waste resources and risk memory exhaustion.

Start with workers equal to CPU cores. If queries are I/O-bound (waiting on database), increase it. If queries are CPU-bound (aggregations, joins), keep it at cores.

For a typical Superset deployment serving 50 concurrent users:

• 4 CPU cores: 4 workers, 4 tasks per worker = 16 concurrent queries.
• 8 CPU cores: 8 workers, 8 tasks per worker = 64 concurrent queries.

Monitor queue depth. If queries regularly queue for > 5 seconds, add workers.

Pattern 2: Query Timeouts and SLAs

Set realistic timeouts. If a query runs longer than your SLA, kill it and let the user know. In superset_config.py:

ASYNC_QUERY_JOB_TIMEOUT = 600  # 10 minutes for dashboards
LONG_RUNNING_QUERY_TIMEOUT = 3600  # 1 hour for reports

Different timeouts for different workloads. Dashboard queries should be fast (< 10 seconds). Report exports can be slow (> 1 hour). Use Superset’s query context to set timeouts per dashboard.

Pattern 3: Result Expiration and Cleanup

Results accumulate in your backend. Without cleanup, Redis fills up or your database grows unbounded. Set result expiration:

CELERY_TASK_TRACK_STARTED = True
CELERY_RESULT_EXPIRES = 86400  # 24 hours

After 24 hours, results are automatically deleted. Adjust based on your workload. Financial services often need 30 days for audit trails; media and retail can use 7 days.

For database backends, implement a cleanup job:

DELETE FROM superset_results WHERE created_at < NOW() - INTERVAL '30 days';

Run this nightly. Monitor result storage size to ensure it doesn’t grow unbounded.

Pattern 4: Prioritising Dashboard Queries

Not all queries are equal. A user waiting for a dashboard refresh needs faster results than a scheduled report running at midnight. Use Celery task routing to prioritise:

CELERY_TASK_ROUTES = {
    'superset.tasks.sql_lab_execute': {'queue': 'sql_lab'},
    'superset.tasks.async_query_manager': {'queue': 'dashboards'},
}

Run separate worker pools for each queue:

# Dashboard queries: 8 workers
celery -A superset.tasks worker -Q dashboards --concurrency=8

# SQL Lab queries: 4 workers
celery -A superset.tasks worker -Q sql_lab --concurrency=4

Dashboard queries get more resources and complete faster. SQL Lab queries (exploratory) get fewer resources but don’t block dashboards.

Pattern 5: Caching Query Results

Superset can cache results for subsequent requests. Configure query caching in superset_config.py:

SUPERSET_QUERY_RESULT_CACHE_CONFIG = {
    'CACHE_TYPE': 'redis',
    'CACHE_REDIS_URL': 'redis://redis-cache:6379/2',
    'CACHE_DEFAULT_TIMEOUT': 3600,  # 1 hour
}

When a user runs a query, Superset checks the cache first. If a result exists and is fresh, it’s returned immediately without re-executing. This dramatically speeds up dashboards with repeated queries.

Set cache TTL based on data freshness requirements. Financial dashboards might cache for 5 minutes. Marketing dashboards for 1 hour. Data warehouse snapshots for 24 hours.

---

Monitoring and Observability

Key Metrics to Track

Instrument your Superset deployment to understand what’s happening. Key metrics:

1. Task Queue Depth: Number of tasks waiting to be processed. If this grows, you need more workers.
2. Task Execution Time: How long queries take from submission to completion. Track p50, p95, p99.
3. Result Backend Latency: How long it takes to write/read results. Should be < 10ms for Redis.
4. Worker Utilisation: Percentage of worker capacity in use. Aim for 60–80%.
5. Cache Hit Rate: Percentage of queries served from cache. Higher is better.
6. Query Timeout Rate: Percentage of queries that exceed timeout. Should be < 1%.

Use Prometheus and Grafana to visualise these metrics. Superset exports metrics via StatsD; configure it:

STATS_LOGGER = [
    'superset.stats_logger.StatsdStatsLogger',
]
STATSD_HOST = 'statsd-server'
STATSD_PORT = 8125
STATSD_PREFIX = 'superset'

Logging and Debugging

Enable detailed logging to understand failures:

LOGGING_CONFIG = {
    'version': 1,
    'formatters': {
        'standard': {
            'format': '%(asctime)s [%(levelname)s] %(name)s: %(message)s'
        },
    },
    'handlers': {
        'console': {
            'class': 'logging.StreamHandler',
            'level': 'INFO',
            'formatter': 'standard',
        },
    },
    'loggers': {
        'superset': {'level': 'INFO'},
        'celery': {'level': 'INFO'},
    },
}

Log to a centralised system (e.g., Elasticsearch, Datadog, CloudWatch) to correlate events across services. When a query fails, you want to see the full trace: web server logs, Celery worker logs, database logs, and result backend logs.

Alerting

Set up alerts for production issues:

• Queue Depth > 100: Workers can’t keep up.
• Task Execution Time > 30s (p95): Queries are slower than expected.
• Result Backend Latency > 50ms: Storage backend is slow.
• Worker Availability < 2: Not enough redundancy.
• Cache Hit Rate < 20%: Cache isn’t helping; investigate why.

Common Pitfalls and Solutions

Pitfall 1: Redis Running Out of Memory

Symptom: Queries fail with “OOM command not allowed when used memory > maxmemory” errors.

Root Cause: Results and cache accumulate faster than they expire. Redis fills up and starts evicting data.

Solution: Set a memory limit and eviction policy in Redis:

maxmemory 8gb
maxmemory-policy allkeys-lru

The allkeys-lru policy evicts the least-recently-used keys when memory is full. Monitor Redis memory usage and increase the limit or add more workers to process queries faster.

Pitfall 2: Celery Workers Crashing

Symptom: Workers process a few queries, then crash. Queries start timing out.

Root Cause: Memory leak in a query or worker process. Long-running queries exhaust memory.

Solution: Set worker memory limits and enable auto-restart:

celery -A superset.tasks worker --max-memory-per-child=512000 --max-tasks-per-child=100

Workers restart after processing 100 tasks or using 512MB of memory. This prevents memory leaks from accumulating.

Pitfall 3: Slow Result Backend Writes

Symptom: Queries complete quickly, but results take minutes to appear.

Root Cause: Result backend is slow or overloaded. Could be Redis CPU saturation, database lock contention, or network latency.

Solution: Profile the backend. For Redis, use redis-cli --latency. For databases, enable slow query logging. Add more backend replicas or scale vertically.

Pitfall 4: Task Queue Backlog

Symptom: Queries queue for hours before executing.

Root Cause: More queries submitted than workers can process. Classic resource contention.

Solution: Add workers, or implement query prioritisation and SLA enforcement. Reject low-priority queries if queue depth exceeds a threshold.

Pitfall 5: Result Expiration Too Aggressive

Symptom: Users can’t retrieve results from earlier queries. Results disappear.

Root Cause: CELERY_RESULT_EXPIRES is too short. Results expire before users access them.

Solution: Increase expiration based on usage patterns. Monitor how long users wait before retrieving results, then set expiration to 2–3× that duration.

Scaling Async Workloads

Horizontal Scaling: Adding Workers

As query volume grows, add worker processes and hosts. Celery scales horizontally by design—each worker is independent and can run on a separate machine.

For Kubernetes, scale the worker deployment:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: superset-worker
spec:
  replicas: 8  # Increase this
  selector:
    matchLabels:
      app: superset-worker
  template:
    metadata:
      labels:
        app: superset-worker
    spec:
      containers:
      - name: worker
        image: superset:latest
        command: ["celery", "-A", "superset.tasks", "worker"]
        resources:
          requests:
            cpu: 2
            memory: 2Gi
          limits:
            cpu: 4
            memory: 4Gi

Start with 4 replicas. Monitor queue depth and scale up if queries queue for > 5 seconds. Scale down if workers are idle.

Vertical Scaling: More Powerful Hosts

If you’re already running many workers, vertical scaling (bigger machines) can help. More CPU cores mean more concurrent queries. More memory means larger datasets can be processed.

But vertical scaling has limits. A single machine can’t have infinite cores. Horizontal scaling is more reliable for large deployments.

Query Optimisation

The best way to scale is to make queries faster. Work with your data team to optimise queries:

• Add indexes on frequently filtered columns.
• Materialised views for common aggregations.
• Partition tables by date or region to reduce scan size.
• Pre-aggregate data in a data warehouse instead of aggregating on the fly.

Optimising queries is often 10× more effective than adding workers. A query that takes 30 seconds can often be optimised to 3 seconds with proper indexing.

For guidance on database and platform optimisation, consider engaging with teams experienced in platform development in Sydney or other major markets who can audit your data architecture and recommend changes.

Integration with Platform Engineering

Superset in a Modern Data Stack

Superset rarely runs in isolation. It’s part of a larger data platform that includes data warehouses (Snowflake, BigQuery, Redshift), data pipelines (dbt, Airflow), and data lakes. Async result storage is one piece of a larger architecture.

When designing your data platform, consider how Superset fits. If you’re building a platform development in Melbourne or platform development in Canberra for regulated industries, async result storage is critical for audit trails and compliance.

Integrate Superset with your data pipeline orchestration. Use Airflow to trigger Superset refreshes on a schedule. Use dbt to build the data models that power your dashboards. Use a data warehouse as the query backend instead of a transactional database.

SOC 2 and Compliance Considerations

If you’re pursuing SOC 2 compliance, async result storage introduces audit requirements. You need to track:

• Who ran which queries and when.
• What results were generated.
• When results were accessed or deleted.
• Whether results were modified.

Enable Superset’s audit logging:

SUPERSET_LOG_QUERY_EXECUTION = True
SUPERSET_SQLLAB_EXECUTION_HISTORY_UI_LIMIT = 100

Store audit logs in a tamper-proof location (e.g., a database with restricted access, or immutable cloud storage). Regularly review logs for anomalies.

For ISO 27001 compliance, ensure your result backend (Redis or database) is encrypted in transit and at rest. Use TLS for network traffic and encrypted volumes for storage.

Kubernetes and Container Orchestration

In modern deployments, Superset runs in Kubernetes. The web server, workers, and result backend are all containerised services. This adds complexity but improves reliability and scalability.

Key considerations:

• Service discovery: Workers need to find the message broker and result backend. Use Kubernetes DNS or a service mesh.
• Resource limits: Set CPU and memory limits to prevent one service from starving others.
• Health checks: Implement liveness and readiness probes so Kubernetes knows when a service is healthy.
• Persistent storage: Result backends need durable storage. Use persistent volumes for databases or managed services for Redis.

For teams building complex data platforms, working with experienced platform development in Toronto or platform development in Austin partners can accelerate time-to-production and ensure your infrastructure is production-ready from day one.

Common Configuration Patterns by Workload

Pattern A: Small Team (< 10 Users, < 100 Queries/Day)

Start simple. A single Redis instance and 2 Celery workers are sufficient.

CELERY_BROKER_URL = "redis://localhost:6379/0"
CELERY_RESULT_BACKEND = "redis://localhost:6379/1"
ASYNC_QUERY_JOB_TIMEOUT = 600
CELERY_RESULT_EXPIRES = 86400

Run workers on the same server as Superset. Monitor manually. This is good enough until you hit 50+ concurrent users.

Pattern B: Growth Phase (50–200 Users, 1000–5000 Queries/Day)

Separate workers from the web server. Use a managed Redis service (AWS ElastiCache, Azure Cache). Add monitoring.

CELERY_BROKER_URL = "redis://redis-broker.example.com:6379/0"
CELERY_RESULT_BACKEND = "redis://redis-results.example.com:6379/1"
ASYNC_QUERY_JOB_TIMEOUT = 300  # Stricter timeout
CELERY_RESULT_EXPIRES = 604800  # 7 days
SUPERSET_QUERY_RESULT_CACHE_CONFIG = {'CACHE_DEFAULT_TIMEOUT': 3600}

Run 4–8 workers on separate instances. Set up Prometheus and Grafana. Implement query prioritisation.

Pattern C: Enterprise (1000+ Users, 50,000+ Queries/Day)

High availability across the board. Redis Sentinel, database replication, multiple worker pools, comprehensive monitoring.

CELERY_BROKER_URL = "redis-sentinel://redis-sentinel:26379/0"
CELERY_RESULT_BACKEND = "redis-sentinel://redis-sentinel:26379/1"
CELERY_RESULT_BACKEND_TRANSPORT_OPTIONS = {
    'master_name': 'mymaster',
    'sentinels': [('sentinel-1', 26379), ('sentinel-2', 26379)],
}
ASYNC_QUERY_JOB_TIMEOUT = 120  # Very strict
CELERY_RESULT_EXPIRES = 2592000  # 30 days (audit requirement)

Run 20+ workers across multiple zones. Implement query routing, result archival, and comprehensive audit logging. Use a data warehouse as the query backend. Engage with experienced platform development in Dallas or platform development in Washington, D.C. teams for enterprise-grade architecture.

Real-World Case Study: D23.io Operational Patterns

D23.io is a data platform built on Superset, serving financial services clients. They process 10,000+ queries daily with < 5-second SLA for dashboards and < 60-second SLA for reports.

Their architecture:

• Message broker: RabbitMQ cluster (3 nodes, disk persistence).
• Result backend: Redis Sentinel (3 nodes, AOF persistence).
• Workers: 16 processes across 4 hosts, split into two queues (dashboards, reports).
• Query backend: Snowflake (optimised data warehouse).
• Monitoring: Prometheus + Grafana + custom alerting.

Key learnings:

1. Separate queues by workload: Dashboard queries get 12 workers, report queries get 4. Dashboards never queue.
2. Aggressive caching: 90% of dashboard queries are served from cache (1-hour TTL). Only 10% hit Snowflake.
3. Query timeouts are features: Dashboard queries timeout at 5 seconds. Users know to optimise slow queries or run them as reports.
4. Audit everything: All query execution is logged to a separate audit database for compliance. Results are archived after 30 days.
5. Invest in query optimisation: 80% of performance improvements came from optimising data models and adding indexes, not from infrastructure scaling.

See PADISO’s case studies for more examples of how teams have scaled analytics platforms.

Advanced Topics

WebSocket-Based Result Streaming

By default, Superset polls for results (client asks every second: “Is it done yet?”). For better UX, enable WebSocket-based result streaming. Results are pushed to the client as soon as they’re ready.

This requires configuring Superset’s WebSocket server and is more complex to operate, but it dramatically improves user experience for long-running queries.

Result Partitioning and Sharding

At extreme scale (100,000+ queries/day), a single result backend becomes a bottleneck. Partition results across multiple Redis instances or database shards. Use consistent hashing to route each result to the same backend.

This requires custom code but enables linear scaling of result storage.

Machine Learning and Predictive Query Routing

Advanced teams use ML to predict query execution time and route slow queries to dedicated workers before they block dashboards. This requires instrumenting historical query data and training a model, but it’s worth it for very large deployments.

Compliance and Security

If you’re planning a compliance audit (SOC 2, ISO 27001, or GDPR), Superset async result storage must be audit-ready. Key requirements:

• Encryption: Results encrypted in transit (TLS) and at rest.
• Access control: Only authorised users can retrieve results.
• Audit trails: All query execution logged with timestamps, user IDs, and outcomes.
• Data retention: Results retained for the required period (typically 30–90 days).
• Disaster recovery: Results can be recovered from backups.

For guidance on building audit-ready infrastructure, consider engaging with security audit specialists who can help you design and implement Superset with SOC 2 or ISO 27001 in mind from the start.

Engaging Platform Engineering Partners

If you’re building a data platform that includes Superset, consider working with experienced partners. Teams in platform development in Australia can help you design the full stack—data warehouse, pipelines, Superset, monitoring, and compliance. Similarly, if you’re in platform development in New York or other major markets, local expertise can accelerate your time-to-production.

Summary

Apache Superset async result storage is not a luxury—it’s essential for production deployments. The right configuration can mean the difference between a responsive, scalable analytics platform and one that times out and frustrates users.

Start with Redis and Celery. Enable async queries. Set reasonable timeouts and result expiration. Monitor relentlessly. Optimise queries. Scale workers as needed. And if you’re pursuing compliance, design for audit trails from day one.

The teams that win at analytics aren’t the ones with the fanciest dashboards—they’re the ones with the most reliable, fastest platforms. Async result storage is the foundation of that reliability.

For more information on building production-grade data platforms, explore PADISO’s platform development services across Australia and internationally. Whether you’re in Melbourne, Sydney, or beyond, the principles in this guide apply. Implement them rigorously, and you’ll have an analytics platform that scales.
