Ok. ILLEGAL INSTRUCTION somewhere inside openssl file generated by perl script https://github.com/ClickHouse-Extras/openssl/blob/master/crypto/arm64cpuid.pl#L73 I think I cannot debug this. You can try to build without ssl support, like `cmake -DENABLE_SSL=OFF`

Culprit: `SELECT isConstant(multiIf('dict1' = 'dict1', 'dictName1', 'dictName2'))` It is the implementation detail of `multiIf`. Yes, it's possible to make it return constant expression in this case.

The test does not work even with infinite retries. Something is wrong with consistency of these metrics? BTW, I don't like the idea to maintaining the consistency manually. Maybe better to move them to AsynchronousMetrics?

Originally, we needed elapsed time in `X-ClickHouse-Progress` HTTP headers for our platform (at Altinity.) It could be probably grafted in an ad-hoc manner somewhere around that code, but that wouldn't be the right way to do it. @alex-zaitsev may provide more details for when we needed this.

this draft can only optimize bitmap copy and join action during the same block. if there are same bitmap in different blocks,this draft has no optimization. On the other way , search for same bitmap on every row will cost some time ,this will slow the query without duplicated bitmap somehow.

Unfortunately, the problem is deeper. We get marks bigger than fixed granularity during the horizontal merge. Vertical merge error is a consequence. The additional check will fail before this bad horizontal merge, but I hope to figure out the error earlier. https://github.com/ClickHouse/ClickHouse/pull/19123

Why don't measure elapsed time on client (clickhouse-client does it to calculate speed)? Another question - how elapsed times are merged from multiple servers in distributed query execution?

They will be published. Currently check status will be green, but individual test results will be written to CI database correctly. And it is currently not committed and I run them manually for debug purposes.

Have no idea what was the reason of the failure, it looks like some network / CI issue (may be smth happened during iptables manipulations).I've did rebase to fresh master, let's see what will happen this time.

More details: Suppose you want to calculate scalar product of two vectors. You can treat first vector as row and second vector as column and do matrix multiplication: `vec1_row * vec2_column` You can also calculate the length of the vector: `sqrt(scalar_product(vec, vec))` But in some coordinate systems you ...

Thanks, @den-crane I think the example I posted, might have been too simple. I know it will fail, would be great to have an alias to be computed only if included on the query.
