> If we run the test, in which we would create a lot of tables (mare than 200? for example), we soon start seeing a degradation in table creation time.
> In particular, handling of corresponding Catalog update might take literal seconds.
> One of the reasons is described here: https://issues.apache.org/jira/browse/IGNITE-19913
> It explains why table creation might be slow, but it does not explain why it degrades when we create more tables. So there are basically two issues:
>  * watch processing waits for unnecessary operations to complete
>  * those operations are too slow for some reason
> We need to investigate and fix both issues
