===========
Due to that cloud provider usually does not support live data migration of a cloud redis service, this tool aims to dump data from one redis-server and restore the dumped data into another redis-server.
- RESTORE import dumped file to target redis-server
redis-transmission -mode=restore -host=127.0.0.1:6379 [-password=Auth] [-input=/path/to/file]- DUMP export file from source redis-server
redis-transmission -mode=dump -host=127.0.0.1:6379 [-password=Auth] [-output=/path/to/file] [-database-count=16] [-thread-count=4]- SYNC synchronize data from source redis-server to destination redis-server
redis-transmission -mode=sync -source=127.0.0.1:6379 -destination=127.0.0.1:6378 [-source-password=Auth] [-destination-password=Auth] [-database-count=16] [-sync-times=Count] [-thread-count=4]- -mode=Mode
Select dump mode, or restore mode. Options: Dump, Restore.
- -host=HostAndPort
The redis instance (host:port).
- -password=PASSWORD
specify the redis auth password, if empty then no use this parameter.
- -input=INPUT
use INPUT as input file
- -output=OUTPUT
use OUTPUT as output file
- -database-count=DATABASE-COUNT
Specify the redis database count
- -source=NODE
The source redis instance (host:port).
- -destination=NODE
The destination redis instance (host:port).
- -source-password=PASSWORD
The source redis authorization password, if empty then no use this parameter.
- -destination-password=PASSWORD
The destination redis authorization password, if empty then no use this parameter.
- -sync-times=TIMES
synchronization times, default loop execution. Do not fill in this parameter if you need to execute it in a loop
- -thread-count=THREAD-COUNT
Number of concurrent executions, if emtpy then use cpu cores count.
- -replace-restore=[1|0]
If the destination-side not support restore command use replace option, please use 0 to off this feature, when off this feature, it will remove key before restore command executive, if empty then use replace option.
