Agrona provides a library of data structures and utility methods that are a common need when building high-performance applications in Java and C++. It supports Buffers, Map, Sets, Cache, Queues and lot more.
<ul>
<li>Buffers - Thread safe direct and atomic for working with on and off heap memory with memory ordering semantics.</li>
<li>Lists - Array backed lists of int/long primitives to avoid boxing.</li>
<li>Maps - Open addressing and linear probing with int/long primitive keys to object reference values.</li>
<li>Maps - Open addressing and linear probing with int/long primitive keys to int/long values.</li>
<li>Sets - Open addressing and linear probing for int/long primitives and object references.</li>
<li>Cache - Set Associative with int/long primitive keys to object reference values.</li>
<li>Clocks - Clock implementations to abstract system clocks, allow caching, and enable testing.</li>
<li>Queues - Lock-less implementations for low-latency applications.</li>
<li>Ring/Broadcast Buffers - implemented off-heap for IPC communication.</li>
<li>Basic Agent framework.</li>
<li>Signal handling to support "Ctrl + c" in a server application.</li>
<li>Scalable Timer Wheel.</li>
<li>Basic code generation from annotated implementations that can vary on primitive types.</li>
<li>Off-heap counters implementation for application telemetry and position tracking.</li>
<li>Implementations of InputStream and OutputStream that can wrap direct buffers.</li>
<li>DistinctErrorLog: A log of distinct errors to avoid filling disks with existing logging approaches.</li>
</ul>
