Is there a way to turn of replica for serving distributed queries, and to stop consuming kafka table, in order to give to the database a chance to merge parts, and afterwards to continue digesting kafka topics and serving as replica.

That should work. Probably you did something wrong. Try to attach same materialized view to the regular table instead of Kafka and try to insert the data into that table.

I'm not expert either in DD, but seems like the Differential Dataflow is a whole another different engine, which is hardly related to our concept of materialized views. If you point out specific peformance or architectural differences between CH and DD approaches, we can try to discuss them in details.

Suppose we have a DateTime column 'created', toRelativeSecondNum(created, 'Europe/Moscow') will be same as toRelativeSecondNum(created, 'UTC'), so the meaning of the second parameter is unclear. The second prob...

This just shows that something wrong with the connection to ZooKeeper, it's not a bug in general. There are a lot of reasons why this can happen and some of them can be on ZooKeeper's side. Also you are using an obsolete version. Update to the latest stable.
