Puddle

Puddle is a tiny generic resource pool library for Go that uses the standard context library to signal cancellation of acquires. It is designed to contain the minimum functionality a resource pool needs that cannot be implemented without concerrency concerns. For example, a database connection pool may use puddle internally and implement health checks and keep-alive behavior without needing to implement any concurrent code of its own.

Features

• Acquire cancellation via context standard library
• Statistics API for monitoring pool pressure
• No dependencies outside of standard library
• High performance
• 100% test coverage
