redis-port

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

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

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

• RESTORE rdb file to target redis

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

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

• SYNC data from master to slave

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

$ 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}
