Activation
This is the description your AI agent reads to decide when to run this skill — the better it matches your request, the more reliably it fires.
Prevent race conditions across multiple instances. Only one instance can hold a lock at a time. Automatic expiration prevents deadlocks.Key capabilities
- →Acquire mutual exclusion locks across instances
- →Enforce automatic TTL expiration for deadlocks
- →Extend lock duration for long-running tasks
- →Support blocking and non-blocking acquisition
- →Track lock ownership via unique holder IDs
How it works
It uses a shared storage mechanism to atomically record lock ownership, ensuring only one process holds the lock at any time.
Inputs & outputs
When to use distributed-lock
- →Synchronize tasks across service instances
- →Prevent race conditions in database updates
- →Manage job queues with single-worker constraints
About distributed-lock
Manages mutual exclusion across distributed services. It uses expiration timers to ensure resources are never locked indefinitely if a process fails.
Prevent race conditions across multiple instances. Only one instance can hold a lock at a time. Automatic expiration prevents deadlocks.
When not to use it
- →When single-instance synchronization is sufficient
- →When the system cannot support a shared state store
Limitations
- →Requires a shared storage backend for multi-instance support
- →TTL must be carefully tuned to match operation duration
How it compares
It provides a distributed-safe locking mechanism that handles process failures via expiration timers, unlike local mutexes.
