------------------------------------------
Summary: Add support for compressed snapshot
Key: ZOOKEEPER-1651
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1651
Project: ZooKeeper
Issue Type: Improvement
Components: server
Reporter: Thawan Kooburat
Assignee: Thawan Kooburat
We want to keep many copies of snapshots on disk so that we can debug the
problem afterward. However, the snapshot can be large, so we added a feature
that allow the server to dump/load snapshot in a compressed format (snappy or
gzip). This also benefit db loading and snapshotting time as well.
This is also depends on client workload. In one of our deployment where clients
don't compress its data, we found that snappy compression work best. The
snapshot size is reduced from 381M to 65MB. Db loading/and snapshotting time is
also reduced by 20%.
