> Key: IGNITE-9599
> URL: https://issues.apache.org/jira/browse/IGNITE-9599
> Project: Ignite
> Issue Type: Improvement
> Reporter: Andrey Kalinin
> Assignee: Alexand Polyakov
> Priority: Minor
>
> In some cases, WAL compression performance is not sufficient, i.e. new
> archives accumulate faster than old ones are compressed.
> We did some tests: the file size of 1GB is compressed at the default
> compression level for 1 minute, the output file size is ~120MB.
> After that, the compression rate was tested with compression-level=-1: 1 GB
> file is compressed in 13 seconds, the output file size is ~125MB.
> So we need add an option to change the default compression level in the
> ignite configuration file.
