Sync two Redis servers using dumps.
rump -from redis://1234.cache.amazonaws.com:6379/1 -to redis://127.0.0.1:6379/1
ElastiCache doesn't support any of the standard Redis backup commands.
Rump is able to transfer keys from an ElastiCache cluster or any Redis server to another Redis server, by only using SCAN, DUMP and RESTORE.
- Uses
SCANinstead ofKEYSto avoid DoS your own server. - Can sync any key type.
- Drops the TTL on purpose, since it wouldn't be in sync.
- Doesn't use any temp file.
- Uses buffered channels to optimize slow source servers.
- Uses pipelines to minimize network roundtrips.
