github.com/jackc/puddle/v2 (go): Package puddle is a generic resource pool with type-parametrized api.  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 concurrency 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.
