Recommended number of concurrent writer threads

[jaisins]

My use case requires writing several thousand messages per sec. 

I use a threadpool, where each thread writes to CQ, in response a prior step. There are about 20-100 threads. 

In order to make things threadsafe, each thread does a createappender(), writes, calls finish() and then close(). 

This overhead consumes most of the resources, ends up with thousands of files (presumably each thread creates a new file on every write operation). The time to write to queue increases from 2- 2000 ms within a few seconds. It is nowhere near ns rates that I assume are normal.

What is the safe number of threads for concurrent writes to ChronicleQueue to achieve a ns rate.

Is my use case, not suitable for ChronicleQueue.

Pardon me, but as i understand you're in the same java process, wouldn't it be more efficient if you used submit all writable stuff to a single thread pool that would write it all to queue? several thousand is not that much as i know...

Anyway as far as i understand you want to have only one writer per process per queue... if you have multiple writer threads you better synchronize inside your java app...
