# Adoption

Oban Pro is designed as a drop-in enhancement to Oban. Once you've [installed](installation.md) the
package and schema, your application automatically benefits from Pro's optimizations without any
code changes.

## Automatic Improvements

Pro replaces several internal operations with optimized implementations that are enabled when you
install the package:

- **Bulk Inserts** — Enqueueing multiple jobs with `enqueue_many` uses a single optimized database
  operation rather than inserting jobs one at a time.

- **Bulk Acking** — Completing, cancelling, snoozing, etc. uses batched updates instead of
  individual queries per job.

- **Accurate Rescue** — Orphaned jobs from node restarts or crashed queues are rescued immediately
  (~60 seconds) rather than waiting for a fixed timeout (5+ minutes). Long-running jobs won't be rescued
  prematurely.

These optimizations reduce database round-trips and improve throughput, especially under high load
or when processing large batches of jobs.

## Multi-Process Execution

For CPU-intensive workloads, switch from `oban start` to `obanpro start` to run jobs across
multiple Python processes. This bypasses the GIL and enables true parallelism utilizing multiple
cores, while respecting your queue's concurrency limits:

```diff
- oban start
+ obanpro start
```

See [Multi-Process](multi_process.md) for configuration options and performance details.

## Next Steps

With Pro installed, you can start using its advanced features:

- [Smart Concurrency](smart_concurrency.md) — Global limits, rate limiting, and partitioned queues
- [Unique Jobs](unique_jobs.md) — Prevent duplicate jobs based on configurable constraints
- [Workflows](workflow.md) — Compose jobs with dependencies for complex pipelines
