### Context I need to create topics on the fly from database table names (cdc) and I'm replacing all `_` with `-`. With current RegexRouter I can't do this in one call (actually if I don't know the number of `_` I don't know how many times I need to call the transformer). That's the reason why I implemented a new flag to allow replaceAll on RegexRouter. ### Change applied I added a new flag `replaceAll` of type `Boolean` with default value `false` which allows to apply a regex replacement in all occurencces of the topic name. I updated the description of the transformer and added 2 tests to cover previous and new behaviour. ### Testing strategy (Unit test) I created a new topic name with two `_` symbols (`sample_table_name`). I called a regex with current implementation expecting only the first `_` to be substituted. I called a regex with new flag expecting all `_` to be replaced with `-`. ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
