Your Question (问题描述)

raft模式，且开启snapshot功能，发现每次执行snapshot的时候耗时都很长
2023-02-22 00:56:26 [store-snapshot-executor2] [INFO] o.a.h.b.s.r.StoreSnapshotFile - Compressed dir '/xxx/snapshot_rocksdb_data' to '/xxx/raft-log/snapshot/temp/snapshot_rocksdb_data.zip', took 1575.661 seconds

数据大小15G左右，耗时近半小时（解压同）。

有没有什么办法可以提高snapshot的效率吗，线上数据量几百G，snapshot的时间估计无法接受了。
