7 Concurrency – BeaverDB: The Complete Guide

# 7 Concurrency

Chapter Outline:

- 7.1. Inter-Process Locks (`db.lock`)
  - Creating a critical section: `with db.lock("my_task", timeout=10): ...`
  - Guarantees: Fair (FIFO) and Deadlock-Proof (via TTL).
- 7.2. Atomic Operations on Data Structures
  - Locking a specific manager: `with db.dict("config") as config: ...`
  - Use Case: Atomically getting and processing a batch of items from a queue.
