Apache Tomcat

Apache Tomcat down

Key Features and Benefits: Simple Implementation: The core of the connection pool is relatively small, with a lower source file count compared to other connection pools. Customizable Interceptors: JDBC Interceptors allow for flexible customization of the pool, query execution, and result set handling. Asynchronous Connection Retrieval: Users can queue requests for connections and receive a Future. Validation Intervals: Connections are validated periodically, but not more frequently than a configured interval, reducing unnecessary validation. Run-Once Query: A configurable SQL query can be executed only once when a connection is established. Fair Queue: The fairQueue feature ensures thread fairness when retrieving connections. Abandoned Connection Handling: Connections can be marked as abandoned based on pool usage or a timeout threshold. High Concurrency Support: The pool is designed to handle high concurrency and multi-core/CPU systems. Integration with JNDI: Tomcat's JDBC pool can be configured and accessed through JNDI (Java Naming and Directory Interface).
