goTRC

A DynamoDB backed distributed locking system written in go

goTRC (short for time-release capsule) is a distributed locking implementation for golang. It has a few qualities which differentiate it from some other implementations.

Reached Goals

• Uses golang-aws-sdk-v2
• Leveled, structured logging using the accepted [slog] package.
• Context native: can use context cancellation to implement automatic release of held locks
• Substantial test coverage
• Built-in lock expiration and lock heartbeats to avoid zombie locks

Future goals (Coming soon!)

• flock-style cli wrapper for commands, such as database migrations
• Automatic distributed testing suite
