Hello,
approx. how long does it take your big query to run as it is now? Are
these queries appending a table? or are they buiding a result (from a
chain of queries)? Have you tried separating them out? Any difference?

Hi,
you have to play with explain to see which index is used in your queries.
Since you defined only mono-column indexes, i think they are not used in
queries with multi-criteria search.
Consider adding indexes with all used columns and eventually drop the not used
ones to not slow updates
We did something similar for our large statistic tables. The older data
that no longer changes would get shipped off into a very fast read only
table with a cron job and then that is the table we would generate the
reports on. Even with millions of entries it is incredibly fast.

If 3.23.22 gave (NULL != 1) = TRUE, that was a bug, because in
SQL, (NULL != 1) is NULL.
