compression.zstd.workers¶

In zstd mode, this enables to configure zstd-internal compression worker threads.

This parameter applies to omfile: File Output Module.

Name:: compression.zstd.workers
Scope:: module
Type:: positive-integer
Default:: module=zlib library default
Required?:: no
Introduced:: 8.2208.0

Description¶

In zstd mode, this enables to configure zstd-internal compression worker threads. This setting has nothing to do with rsyslog workers. The zstd library provides an enhanced worker thread pool which permits multithreaed compression of serial data streams. Rsyslog fully supports this mode for optimal performance.

Please note that for this parameter to have an effect, the zstd library must be compiled with multithreading support. As of this writing (2022), this is not the case for many frequently used distros and distro versions. In this case, you may want to custom install the zstd library with threading enabled. Note that this does not require a rsyslog rebuild.
