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

@hnyoumfk 接上条没打完。。。
使用如下命令：
./rct -f mem -s ~/Desktop/redis-recommend-20180531-0001.rdb -o ~/Desktop/dump_ddd.mem -l 500

1.使用 Release 版本出现下列错误：
Unsupported field: YearOfEra

2.使用源码编译版本出现下列错误：
Exception in thread "main" java.lang.NullPointerException
