Suppose you have a PARTITIONed table with 1000 partitions (nearly the limit).
PARTITION likes to open all the sub-tables, correct?
So, you should probably have table_open_cache > 1000, correct?
But, then that leads to the 'bug' where that cache is (was?) linearly (that is, inefficiently) searched, correct?
Conclusion: PARTITION with 1000 tables is likely to be less efficient than you might think.
