Low latency message queue

With Chronicle Queue you are able to persist every single event and message, It records each event to a memory mapped file.

What is Chronicle Queue Enterprise?

This memory mapped file is also used for exceptionally fast interprocess communication (IPC) without affecting your system performance. This is especially useful when there is a need to transfer large amounts of data, its ideal for transferring data between processes very quickly on the same server or across the network. There is no Garbage Collection (GC) as everything is done off heap.

TCP replication ensures that data is kept in sync. TCP replication also provides further resilience and failover, our low latency message queue is ideal for distributed architectures especially when you wish to spread the processing over more than one machine and achieve a High level of Availability (HA).

Chronicle Queue Enterprise Features

No data loss; stores every value instead of replacing them

No GC as everything is done off-heap

Persistence to disk through memory mapped files

IPC between Java processes or between threads in a Java process

Simple API for ease of use

Replay-ability of all your inputs and outputs

Concurrent writers across processes on the same machine

Concurrent readers across machines on your network using TCP replication

Exclusive feature of Enterprise

Embedded performance in all processes

All data stored off-heap, to reduce GC impact

Data is written synchronously to ensure no data is lost

Data is read less than a microsecond after it is written

Low latency message queue, durable, interprocess communication (IPC)

How does it work?

Our low latency message queue 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.

We also have a version which offers a cut down feature set but delivers even lower latencies. Click here to learn more.
