Oban Pro - Durable Background Job Processing for Elixir and Python

Oban Pro layers enterprise-grade features on top of Oban's open-source foundation to help you scale complex background job systems with confidence. Backed entirely by Postgres, Oban Pro delivers durable workflows, smart concurrency control, and a real-time dashboard - all without additional infrastructure.

Background job systems are the backbone of modern applications. Whether you are orchestrating AI pipelines, processing billing events, managing media transformations, or running ETL workloads, Oban Pro gives you the tools to build reliable, high-throughput async systems that survive crashes, restarts, and deploys.

• Compose jobs with arbitrary dependencies for sequential, fan-out, and fan-in execution
• Every step is checkpointed in Postgres and execution resumes from the last completed step
• Saga-style compensations automatically reverse completed jobs when a workflow is cancelled
• Cascading functions flow results into downstream jobs without manual threading
• Sub-workflows enable reuse and composition of complex pipeline patterns

• Global concurrency limits coordinated across your entire cluster
• Rate limiting with fixed, leaky-bucket, or token-bucket algorithms
• Granular queue partitioning with independent budgets per tenant or account
• Burst mode to maximize throughput when capacity is available
• 92% fewer queries and 96% fewer transactions compared to the open-source engine

• Decorators: Turn any function into a background job without a separate worker module
• Relay: Insert a job and await its result synchronously from any node in the cluster
• Chains: Force strict sequential execution across related jobs
• Batches: Group jobs and fire callbacks on transitions like completion or cancellation
• Chunks: Execute multiple jobs within a single function, triggered by availability or timeout
• Encrypted Args: Transparently encrypt sensitive data at rest in the database
• Awaiting Signals: Pause jobs mid-execution to wait for human approval or external events
• Structured Args: Define typed args with validation so malformed payloads fail fast
• Recorded Output: Capture and persist job return values for downstream consumption

• Dynamic queue management with changes persisted across restarts
• Runtime-editable pruning rules matching any combination of queue, worker, and state
• Job archiving to retain pruned jobs in a separate table for auditing
• Dynamic prioritizer to automatically promote aging low-priority jobs
• Dynamic scaler for horizontal scaling based on predictive throughput

The Pro Smart Engine dramatically reduces database load while increasing job throughput:

• 92% fewer queries through batched, parameterized inserts
• 96% fewer transactions with async tracking
• Accurate job retry after shutdown without waiting for timeouts

Oban Pro supports both Elixir and Python runtimes, giving teams flexibility regardless of their language stack. The same workflow patterns, concurrency controls, and operational tools are available on both platforms.

For organizations requiring dedicated support, private Slack or Teams channels, video call support, priority access to new features, and ongoing configuration review, Oban Pro offers enterprise licensing with volume options and multi-year agreements.

Oban Web brings your entire cluster into one real-time dashboard. Monitor every job, queue, schedule, and workflow streaming live. Pause queues, retry or cancel jobs, and trigger crons on demand - all without a deploy. Built-in metrics cover throughput, queue depth, and execution time with no extra infrastructure required.
