redis-port

parse redis rdb file, sync data between redis master and slave

DECODE dumped payload to human readable format (hex-encoding)

bash

redis-port decode    [--ncpu=N] [--parallel=M] \
    [--input=INPUT] \
    [--output=OUTPUT]

RESTORE rdb file to target redis

bash

redis-port restore   [--ncpu=N] [--parallel=M] \
    [--input=INPUT]  [--faketime=FAKETIME] [--extra] [--filterdb=DB] \
     --target=TARGET [--auth=AUTH] [--redis|--codis]

DUMP rdb file from master redis

bash

redis-port dump      [--ncpu=N] [--parallel=M] \
     --from=MASTER   [--password=PASSWORD] [--extra] \
    [--output=OUTPUT]

SYNC data from master to slave

bash

redis-port sync      [--ncpu=N] [--parallel=M] \
     --from=MASTER   [--password=PASSWORD] [--psync] [--filterdb=DB] \
     --target=TARGET [--auth=AUTH] [--redis|--codis] [--sockfile=FILE [--filesize=SIZE]]

Options

-n N, --ncpu=N

set runtime.GOMAXPROCS to N

-p M, --parallel=M

set number of parallel routines

-i INPUT, --input=INPUT

use INPUT as input file, or if it is not given, redis-port reads from stdin (means '/dev/stdin')

-o OUTPUT, --output=OUTPUT

use OUTPUT as output file, or if it is not given, redis-port writes to stdout (means '/dev/stdout')

-m MASTER, --master=MASTER

specify the master redis

-t TARGET, --target=TARGET

specify the slave redis (or target redis)

-P PASSWORD, --password=PASSWORD

specify the redis auth password

-A AUTH, --auth=AUTH

specify the auth password for target

-e, --extra

dump or restore following redis backlog commands

--redis

target is normal redis instance, default value is false.

--codis

target is codis proxy, default value is true.

--filterdb=DB

filter specifed db number, default value is '*'

Examples

DECODE

bash

$ cat dump.rdb | ./redis-port decode 2>/dev/null
 {"db":0,"type":"string","key":"a","value":"hello"}
 {"db":1,"type":"string","key":"a","value":"9"}
 {"db":0,"type":"hash","key":"c","field":"hello","value":"world"}
 {"db":0,"type":"expire","key":"c","expireat":1487663341422}
 {"db":0,"type":"list","key":"b","index":0,"value":"hello"}
 {"db":0,"type":"list","key":"b","index":1,"value":"world"}
 {"db":0,"type":"zset","key":"d","member":"hello","score":1}
 {"db":0,"type":"zset","key":"d","member":"world","score":1.8}
  ... ...
