FlexyPool is a Java library that wraps existing JDBC connection pools (HikariCP, DBCP, C3P0, Tomcat CP, Vibur, Druid, Atomikos) to add metrics collection and dynamic resizing strategies. It gathers histograms of connection usage, acquisition times, and pool sizes, and can adjust pool size on demand with failover strategies.
Use cases
- monitor jdbc connection pool metrics
- auto-resize database connection pool on demand
- collect connection acquisition time histograms
- add failover strategies to hikaricp
- diagnose connection pool sizing issues
- track concurrent database connections in java app
When to choose
- you use a Java connection pool and need runtime metrics or dynamic resizing
- you want histogram statistics on connection usage without switching pools
- you need pool failover strategies across multiple pool implementations
When to avoid
- you use a non-JVM language
- your pool already provides sufficient metrics and you don't need dynamic resizing
- you want a standalone connection pool rather than a wrapper
