Document

Install

Binary package

Download from Release: https://github.com/alibaba/RedisShake/releases

Compile from source

After downloading the source code, run the sh build.sh command to compile.

git clone https://github.com/alibaba/RedisShake
cd RedisShake
sh build.sh

Usage

Edit sync.toml or restore.toml.
Start redis-shake.

./bin/redis-shake redis-shake.toml
# or
./bin/redis-shake restore.toml

Check data synchronization status.

Configure

The redis-shake configuration file refers to sync.toml or restore.toml.

Data filtering

redis-shake supports custom filtering rules using lua scripts. redis-shake can be started with the following command:

./bin/redis-shake sync.toml filter/xxx.lua

Some following filter templates are provided in filter directory:

filter/print.lua：print all commands
filter/swap_db.lua：swap the data of db0 and db1

Custom filter rules

Refer to filter/print.lua to create a new lua script, and implement the filter function in the lua script. The arguments of the function are:

id: command id
is_base: is the command read from the dump.rdb file
group: command group, see the description file under redis/src/commands
cmd_name: command name
keys: keys in command
slots: slots in command
db_id: database id
timestamp_ms: timestamp of the command in milliseconds. The current version does not support it.

The return value is:

code
- 0: allow this command to pass
- 1: this command is not allowed to pass
- 2: this command should not appear, and let redis-shake exit with an error
db_id: redirected db_id
