使用
usage: rct -f <format> -s <source> -o <file> [-d <num num...>] [-e <escape>] [-k <regex regex...>] [-t <type type...>] [-b <bytes>] [-l <n>] [-r] options: -b,--bytes <bytes> limit memory output(--format mem) to keys greater to or equal to this value (in bytes) -d,--db <num num...> database number. multiple databases can be provided. if not specified, all databases will be included. -e,--escape <escape> escape strings to encoding: raw (default), redis. -f,--format <format> format to export. valid formats are json, dump, diff, key, keyval, mem and resp -h,--help rct usage. -k,--key <regex regex...> keys to export. this can be a regex. if not specified, all keys will be returned. -l,--largest <n> limit memory output(--format mem) to only the top n keys (by size). -o,--out <file> output file. -r,--replace whether the generated aof with <replace> parameter(--format dump). if not specified, default value is false. -s,--source <source> <source> eg: /path/to/dump.rdb redis://host:port?authPassword=foobar redis:///path/to/dump.rdb. -t,--type <type type...> data type to export. possible values are string, hash, set, sortedset, list, module, stream. multiple types can be provided. if not specified, all data types will be returned. -v,--version rct version. examples: rct -f dump -s ./dump.rdb -o ./appendonly.aof -r rct -f resp -s redis://127.0.0.1:6379 -o ./target.aof -d 0 1 rct -f json -s ./dump.rdb -o ./target.json -k user.* product.* rct -f mem -s ./dump.rdb -o ./target.aof -e redis -t list -l 10 -b 1024
usage: rmt -s <source> -m <uri> [-d <num num...>] [-k <regex regex...>] [-t <type type...>] [-r] options: -d,--db <num num...> database number. multiple databases can be provided. if not specified, all databases will be included. -h,--help rmt usage. -k,--key <regex regex...> keys to export. this can be a regex. if not specified, all keys will be returned. -m,--migrate <uri> migrate to uri. eg: redis://host:port?authPassword=foobar. -r,--replace replace exist key value. if not specified, default value is false. -s,--source <source> <source> eg: /path/to/dump.rdb redis://host:port?authPassword=foobar redis:///path/to/dump.rdb -t,--type <type type...> data type to export. possible values are string, hash, set, sortedset, list, module, stream. multiple types can be provided. if not specified, all data types will be returned. -v,--version rmt version. examples: rmt -s redis://120.0.0.1:6379 -m redis://127.0.0.1:6380 -d 0 rmt -s ./dump.rdb -m redis://127.0.0.1:6380 -t string -r
usage: rdt [-b <source> | -s <source> -c <file> | -m <file file...>] -o <file> [-d <num num...>] [-k <regex regex...>] [-t <type type...>] options: -b,--backup <source> backup <source> to local rdb file. eg: /path/to/dump.rdb redis://host:port?authPassword=foobar redis:///path/to/dump.rdb -c,--config <file> redis cluster's <nodes.conf> file(--split <source>). -d,--db <num num...> database number. multiple databases can be provided. if not specified, all databases will be included. -h,--help rdt usage. -k,--key <regex regex...> keys to export. this can be a regex. if not specified, all keys will be returned. -m,--merge <file file...> merge multi rdb files to one rdb file. -o,--out <file> if --backup <source> or --merge <file file...> specified. the <file> is the target file. if --split <source> specified. the <file> is the target path. -s,--split <source> split rdb to multi rdb files via cluster's <nodes.conf>. eg: /path/to/dump.rdb redis://host:port?authPassword=foobar redis:///path/to/dump -t,--type <type type...> data type to export. possible values are string, hash, set, sortedset, list, module, stream. multiple types can be provided. if not specified, all data types will be returned. -v,--version rdt version. examples: rdt -b ./dump.rdb -o ./dump.rdb1 -d 0 1 rdt -b redis://127.0.0.1:6379 -o ./dump.rdb -k user.* rdt -m ./dump1.rdb ./dump2.rdb -o ./dump.rdb -t hash rdt -s ./dump.rdb -c ./nodes.conf -o /path/to/folder -t hash -d 0 rdt -s redis://127.0.0.1:6379 -c ./nodes.conf -o /path/to/folder -d 0
过滤
rct, rdt 和 rmt 这3个命令支持type,db,key正则表达式数据过滤
举例如下:
rct -f dump -s /path/to/dump.rdb -o /path/to/dump.aof -d 0 rct -f dump -s /path/to/dump.rdb -o /path/to/dump.aof -t string hash rmt -s /path/to/dump.rdb -m redis://192.168.1.105:6379 -r -d 0 1 -t list
Redis大量数据插入
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
把rdb转换成dump格式
rct -f dump -s /path/to/dump.rdb -o /path/to/dump.aof
把rdb转换成json格式
rct -f json -s /path/to/dump.rdb -o /path/to/dump.json
找到占用内存最大的50个key
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
把rdb转换成RESP格式
rct -f resp -s /path/to/dump.rdb -o /path/to/appendonly.aof
同步rdb到远端redis
rmt -s /path/to/dump.rdb -m redis://192.168.1.105:6379 -r
备份远端redis的rdb
rdt -b redis://192.168.1.105:6379 -o /path/to/dump.rdb
过滤rdb
rdt -b /path/to/dump.rdb -o /path/to/filtered-dump.rdb -d 0 -t string
通过集群的nodes.conf把1个rdb分割成多个rdb
rdt -s ./dump.rdb -c ./nodes.conf -o /path/to/folder -d 0
合并多个rdb成1个
rdt -m ./dump1.rdb ./dump2.rdb -o ./dump.rdb -t hash
