low-gc-membuffers

Stores data in direct ByteBuffers outside the Java heap, significantly reducing garbage collection overhead, as emphasized in the project's core philosophy for performance-critical systems.

All buffer accesses are synchronized, enabling safe use by multiple producer and consumer threads, which is explicitly stated in the README's thread-safety section.

Used in production since 2012 by companies like Salesforce, with a stable 1.0 release in 2013, indicating reliability for high-throughput applications.

Supports both chunky (discrete entries) and streamy (coalesced entries) buffers for bytes and longs, allowing optimization for different data patterns, as detailed in the buffer variations.

Enables buffer groups to share underlying segment allocators, facilitating memory reuse and strict bounds, which is highlighted in the 'Fancier stuff: multiple buffers' section.
