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]  [--input=INPUT]  [--output=OUTPUT]

• RESTORE rdb file to target redis

redis-port restore  [--ncpu=N]  [--input=INPUT]   --target=TARGET  [--extra]

• DUMP rdb file from master redis

redis-port dump     [--ncpu=N]   --from=MASTER   [--output=OUTPUT] [--extra]

• SYNC data from master to slave

redis-port sync     [--ncpu=N]   --from=MASTER    --target=TARGET  [--sockfile=FILE [--filesize=SIZE]] [--filterdb=DB]

Options

• -n N, --ncpu=N

set runtime.GOMAXPROCS to N

• -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)

• -e, --extra

dump or restore following redis backlog commands

• --filterdb=DB

filter specifed db number, default is '*'

Examples

• DECODE

$ cat dump.rdb | ./redis-port decode 2>/dev/null
