配置文件
RedisShake 使用 TOML 语言书写，所有的配置参数在 all.toml 中均有说明。
配置文件的组成如下：
toml
function = "..."
[xxx_reader]
...
[xxx_writer]
...
[advanced]
...一般用法下，只需要书写 xxx_reader、xxx_writer 两个部分即可，function 和 advanced 部分为进阶用法，用户可以根据自己的需求进行配置。

# redis-shake gets key and value from rdb file, and uses RESTORE command to
# create the key in target redis. Redis RESTORE will return a "Target key name
# is busy" error when key already exists. You can use this configuration item
# to change the default behavior of restore:
# panic: redis-shake will stop when meet "Target key name is busy" error.
# rewrite: redis-shake will replace the key with new value.
# ignore: redis-shake will skip restore the key when meet "Target key name is busy" error.
