Missing few mirrormaker basics

I have few issues :

1) **Topic metadata does not replicate** to destination when brooklin datastream is setup. And neither it replicate **modifications** in same. What I can configure to do same ?
2) How can I configure change in topic name in destination? Fo example, in source , I have a topic name **first-topic** and I have a datastream setup to mirror it in destination cluster with topic name as **first-topic.global** ?

Start by reviewing Brooklin datastream configuration and the mirroring path for topic metadata and destination naming. Confirm whether metadata replication, metadata updates, and source-to-destination topic renaming are supported; done requires a documented configuration or a clearly scoped change with expected behavior.
