--compress参数对tokudb表有作用吗?

[Fanduzi]

innobackupex --defaults-file=/data/mysqldata/3306/my.cnf --user=root --password="x'x" --parallel=10 --compress --compress-threads=10 \ --stream=xbstream ./ > /data3/backup/full.xbstream

数据文件399G 备份完了居然389G, 完全没压缩一样

'--compress' flag has almost no effect here, since TokuDB data files are already compressed, it just waste your CPU and slowing down the backup.
