如何指定目标redis的库号？

[sxlstevengit]

工作中遇到这样的场景：把源库中所有DB的数据， 全部同步到目标库DB 1中，需要怎么配置？
我查到redis-shake2.0.3具有这个功能，指定：target.db = 1即可。 但是最新版本没有这个配置选项，请问最新版如何实现？

参考交换 DB 的脚本，写一个符合你需求的脚本：https://tair-opensource.github.io/RedisShake/zh/filter/function.html#%E4%BA%A4%E6%8D%A2-db

我试过交换DB的配置，还是不能指定目标redis的库号，请问有最佳实践吗 @suxb201 @sxlstevengit
配置文件：
function = """
shake.log(DB)
local db1 = 0
local db2 = 9

if DB == db1 then
DB = db2
end
shake.call(DB, ARGV)
"""

[scan_reader]
cluster = false # set to true if source is a redis cluster
address = "127.0.0.1:6379" # when cluster is true, set address to one of the cluster node
username = "" # keep empty if not using ACL
password = "redis01pass" # keep empty if no authentication is required
ksn = false # set to true to enabled Redis keyspace notifications (KSN) subscription
tls = false

[redis_writer]
cluster = false # set to true if target is a redis cluster
address = "127.0.0.1:6380" # when cluster is true, set address to one of the cluster node
username = "" # keep empty if not using ACL
password = "redis01pass" # keep empty if no authentication is required
tls = false

运行结果：

function 在 filter 下面，你需要开头写 [filter]

https://github.com/tair-opensource/RedisShake/blob/v4/shake.toml 函数在filter下面，你需要写[filter]

可以了，你真棒
