Proxy Power: Boosting Java App Performance with Open J Proxy

Please note that registration via EventBrite is required for in-person attendance. Also, we will not be livestreaming this meeting, but the recording will be available afterwards.

We are happy to announce that Rogério Robetti will be our special guest for this second (of two) meetings in December.

Abstract

Open J Proxy (OJP) is an open-source project that rethinks JDBC data source interactions for Java applications. By providing built-in backpressure through controlled connection handling and a built-in circuit breaker, also introducing slow query segregation - ensuring long-running queries cannot monopolize the pool resources - OJP delivers predictable performance, improved fault tolerance, and stronger reliability.

With seamless integration into modern Java stacks, OJP empowers developers to build database-driven systems that remain responsive under heavy load.
