Original topic: lightning完整配置参数中为什么没有routes了?

I remember that the configuration parameters used to include an explanation for routes. I just checked and found that from version 5.4 to version 7.5, the official documentation no longer includes this category of parameter configuration.

Is it possible that you remembered incorrectly? This parameter should belong to DM.

Lightning has routes, but the feature is hidden. It can be used but is not recommended.

Could you please explain the reasons for not recommending it?

| username: WalterWj | Original post link

Because the parameters are hidden. The hiding feature is rarely used.

There are new replacements, right?

| username: WalterWj | Original post link

There might be, depending on market demand.

Actually, you can use regular expressions to map filenames to database and table names here, but it’s not as flexible as DM.

Refer to the official documentation for using regular expressions to replace: TiDB Lightning 数据源 | PingCAP 文档中心

Version 6.5 can also be used.
