LOW-LATENCY MESSAGING FRAMEWORK

Chronicle Queue Enterprise

Chronicle Queue is a leading choice for organisations seeking a low-latency, high-performance messaging framework.

The Chronicle Queue Enterprise version eliminates compatibility issues and allows for the seamless integration and sharing of data between Java, Rust, Python and C++ libraries.

"I am an admirer of all things Chronicle, I can honestly say, Chronicle Queue changed my entire perspective"

Eliminate Compatibility Issue with Chronicle Queue Enterprise

  • Build your queue messaging system with the flexibility to use Java, Python, C++, or Rust and leverage the strengths of each.
  • Ensure efficient interoperability whilst minimising development time and enhancing system performance.
  • Chronicle Queue supports throughputs of millions of events per second, with stable, sub microsecond latencies.  
  • Compared against Chronicle’s original open-source Java Queue, the C++ and Rust variants show lower latencies and tighter jitter, with Python queue a little higher reflecting the fact that it is an interpreted language.

Reducing Tail Latencies with Chronicle Queue Enterprise

Persistent queue solutions are frequently used when designing low-latency applications. The problem is that high sustained message rates, or bursty workloads, can lead to delays caused by the OS or hardware which are challenging to mitigate. In this article, we will describe how Chronicle Queue Enterprise solves this. Background When benchmarking Java low-latency persistent queue…

Chronicle Queue storing 1TB in virtual memory on a 128GB machine

If you use a standard JVM like the Oracle JVM or the OpenJDK, you might find that as the heap size grows the performance of your JVM can drop as GC pause time escalates. This tends to be a problem around 32 GB of heap, but it often depends on the application at which point…
