https://github.com/leonchen83/redis-cli-tool

Redis mass insertion

 rct -f dump -s /path/to/dump.rdb -o /path/to/dump.aof -r cat /path/to/dump.aof | /redis/src/redis-cli -p 6379 --pipe 

Convert rdb to dump format

rct -f dump -s /path/to/dump.rdb -o /path/to/dump.aof 

Convert rdb to json format

rct -f json -s /path/to/dump.rdb -o /path/to/dump.json 

Find top 50 largest keys

rct -f mem -s /path/to/dump.rdb -o /path/to/dump.mem -l 50 

Diff rdb

rct -f diff -s /path/to/dump1.rdb -o /path/to/dump1.diff rct -f diff -s /path/to/dump2.rdb -o /path/to/dump2.diff diff /path/to/dump1.diff /path/to/dump2.diff 

Convert rdb to RESP

rct -f resp -s /path/to/dump.rdb -o /path/to/appendonly.aof 

Migrate rdb to remote redis

rmt -s /path/to/dump.rdb -m redis://192.168.1.105:6379 -r 

Backup remote redis's rdb

rdt -b redis://192.168.1.105:6379 -o /path/to/dump.rdb 

Filter rdb

rdt -b /path/to/dump.rdb -o /path/to/filtered-dump.rdb -d 0 -t string 

Split rdb via cluster's nodes.conf

rdt -s ./dump.rdb -c ./nodes.conf -o /path/to/folder -d 0 

Merge multi rdb to one

rdt -m ./dump1.rdb ./dump2.rdb -o ./dump.rdb -t hash
