real-logic/agrona: High Performance data structures and utility methods for Java
- Buffers - Thread safe direct and atomic buffers for working with on and off heap memory with memory ordering semantics.
- Lists - Array backed lists of int/long primitives to avoid boxing.
- Maps - Open addressing and linear probing with int/long primitive keys to object reference values.
- Maps - Open addressing and linear probing with int/long primitive keys to int/long values.
- Sets - Open addressing and linear probing for int/long primitives and object references.
- Cache - Set Associative with int/long primitive keys to object reference values.
- Clocks - Clock implementations to abstract system clocks, allow caching, and enable testing.
- Queues - Lock-less implementations for low-latency applications.
- Ring/Broadcast Buffers - implemented off-heap for IPC communication.
- Simple Agent framework for concurrent services.
- Signal handling to support "Ctrl + c" in a server application.
- Scalable Timer Wheel - For scheduling timers at a given deadline with O(1) register and cancel time.
- Code generation from annotated implementations specialised for primitive types.
- Off-heap counters implementation for application telemetry, position tracking, and coordination.
- Implementations of InputStream and OutputStream that can wrap direct buffers.
- DistinctErrorLog - A log of distinct errors to avoid filling disks with existing logging approaches.
- IdGenerator - Concurrent and distributed unique id generator employing a lock-less implementation of the Twitter Snowflake algorithm.
