Document

Install

Binary package

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

Compile from source

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

sh build.sh

Usage

1. Edit redis-shake.toml and modify the source and target configuration items in it.
2. Start redis-shake.

./bin/redis-shake redis-shake.toml

3. Check data synchronization status.

Configure

The redis-shake configuration file refers to redis-shake.toml. In order to avoid ambiguity, it is mandatory that each configuration in the configuration file needs to be assigned a value, otherwise an error will be reported.

Data filtering

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

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

Some following filter templates are provided in filter directory:

1. filter/print.lua：print all commands
2. 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

Contribution

Lua script

Welcome to share more creative lua scripts.

1. Add lua scripts under filters/.
2. Add description to README.md.
3. Submit a pull request.

Redis Module support

1. Add code under internal/rdb/types.
2. Add a command file under scripts/commands, and use the script to generate a table.go file and move it to the internal/commands directory.
3. Add test cases under test/cases.
4. Submit a pull request.

redis-shake 旧版是阿里云基于豌豆荚开源的 redis-port 进行二次开发的一个支持 Redis 异构集群实时同步的工具。 redis-shake v3 在 redis-shake 旧版的基础上重新组织代码结构，使其更具可维护性的版本。

redis-shake v3 参考借鉴了以下项目：
