What is Chronicle Queue?
Chronicle Queue is a persisted low-latency messaging framework for high performance and critical applications, it can be used for low latency Interprocess communication (IPC) without affecting your system performance this can be useful when transferring large amounts of data between processes. It is a "record everything store" which can read with microsecond real-time latency and supports even the most demanding low latency trading systems.
Although it is not just limited to trading it can be used in any application where the recording and movement of information is a concern. There is also no Garbage Collection (GC) as everything is off heap.
Chronicle Queue Features
How does it work?
Chronicle uses a memory mapped file to continuously journal messages, Chronicle's file-based storage will slowly grow in size as more data is written to the queue, the size of the queue can exceed your available memory, you are only constrained by the amount of disk space you have on your server. Chronicle writes data directly into off-heap memory which is shared between java processes on the same server.
Chronicle is very fast, it is able to write and read a message in just two microseconds with no garbage. Typically at the end of each day, you archive the queue and start the next day with a fresh empty queue.
