Enable compression for backups

There is a possibility to enable LZ4 compression for backups.

Note

This feature is available only with Percona XtraDB Cluster 8.0 and not Percona XtraDB Cluster 5.7.

To enable compression, use pxc.configuration key in the deploy/cr.yaml configuration file to supply Percona XtraDB Cluster nodes with two additional my.cnf options under its [sst] and [xtrabackup] sections as follows:

pxc:
  image: percona/percona-xtradb-cluster:8.0.19-10.1
  configuration: |
    ...
    [sst]
    xbstream-opts=--decompress
    [xtrabackup]
    compress=lz4
    ...

When enabled, compression will be used for both backups and SST .
