Subject [jira] [Updated] (IGNITE-9599) Add ability to manage compression level for compressed WAL archives
Date Fri, 14 Sep 2018 09:25:00 GMT

]

Andrey Kalinin updated IGNITE-9599:
-----------------------------------
    Description: 
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.
