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]]- -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 '*'
- DECODE
