One particular query type is about count. But it is not to count every row in the table. One count example is: SELECT COUNT(ID) FROM some-table PREWHERE CREATION_DATE BETWEEN '2021-03-22 22:48:15' AND '2021-03-22 23:18:15' I will run the same test on the latest stable release along with the perf tool installed.

It's relatively recent (since 21.1) so maybe it's OK.... How did you fix the sharding, just copied it all with clickhouse-copier, or there is some simpler way?

@alesapin Maybe merge this PR now and implement CRTP for data types later? However, it will not avoid of saving precomputied pointers to serializations in some cases, when dynamic serializations will be ready, because they anyway will give overhead for choosing serialization and creating a new object.

Yeah that makes sense. We'll move to a similar approach, calculating client time at ingest rather than query time. It's simpler and has additional benefits like making our indexes better aligned with queries.

By the way, what did it return before for 3+ level custom top-level domains? Just didn't find them and defaulted to second-level? Maybe this should be "Bugfix" and not "Backwards-incompatible", if the previous behavior was just wrong.
