![]() The abandon connection timer will reset upon a statement/query activity.You can decide at what moment connections are considered abandoned, is it when the pool is full, or directly at a timeout.Instead of closing connections directly, it can still pool connections and sizes the idle pool with a smarter algorithm. Asynchronous connection retrieval - you can queue your request for a connection and receive a Future back.Complexity reduction has been a focus from inception. As bugs may occur, they will be faster to track down, and easier to fix. That has over 200 source files(last time we checked), Tomcat jdbc has a core of 8 files, the connection pool itself is about half Extremely simple, due to the very simplified implementation, the line count and source file count are very low, compare with c3p0.High performance - we will show some differences in performance later on.Your options are endless and the interceptors are dynamic, not tied to a JDK version of a You can use interceptors to gather query stats,Ĭache session states, reconnect the connection upon failures, retry queries, cache query results, and so on. This allows you to write custom interceptors to enhance the functionality. Ability to configure custom interceptors.Very useful to setup session settings, that you want to exist during the entire time the connection is established. Run-Once query, a configurable query that will be run only once, when the connection to the database is established.When we borrow or return the connection, just not more frequent than an interval we can configure. Validation intervals - we don't have to validate every single time we use the connection, we can do this.Your runtime environment (as long as your JDBC driver does the same), even when compiled with a lower version of the JDK. Dynamic implementation of interface, will support java.sql and javax.sql interfaces for.Support for highly concurrent environments and multi core/cpu systems.Most pools will simply starve.įeatures added over other connection pool implementations If a pool is empty, and threads are waiting for aĬonnection, when a connection is returned, the pool will awake theĬorrect thread waiting. ![]() Retrieve the underlying connection using the.Simplified logging framework used in Tomcat. ![]()
