# Oban Pro

Oban Pro is a licensed add-on for the Oban job orchestration framework. It provides extensions
that expand what Oban is capable of while making complex workflows possible.

Get started with [installation](installation.md), learn how to transition from OSS to Pro
with [adoption](adoption.md), then explore the features below.

## Features

### Drop-In Optimizations

Install Pro and your application automatically benefits from bulk inserts, bulk acking, and
accurate orphan rescue—no code changes required. [Learn more →](adoption.md)

### Multi-Process Execution

Bypass the GIL and utilize multiple CPU cores for CPU-intensive workloads. Just switch from
`oban start` to `obanpro start`. [Learn more →](multi_process.md)

### Smart Concurrency

Control job execution with global concurrency limits across all nodes, rate limiting
(e.g., 60 jobs/minute), and partitioned queues that apply limits per worker, tenant, or
any argument. [Learn more →](smart_concurrency.md)

### Unique Jobs

Prevent enqueueing duplicate jobs based on worker, args, queue, or specific keys. Configure
time windows and detect conflicts. [Learn more →](unique_jobs.md)

### Relay

Dispatch jobs and wait for their results with synchronous-style semantics. Perfect for
request/response workflows and service coordination. [Learn more →](relay.md)

### Workflows

Compose jobs with dependencies for sequential, fan-out, and fan-in execution patterns.
Supports sub-workflows, cascading functions for automatic result passing, and runtime
grafting for dynamic pipelines. [Learn more →](workflow.md)
