What version of mysql is this again?
My explain output looks like this:
+----------------------+--------+-----------------------------
+---------+---------+-------------------------------+------
+-----------------------------------------------------------+
| table | type | possible_keys |
key | key_len | ref | rows |
Extra |
+----------------------+--------+-----------------------------
+---------+---------+-------------------------------+------
+-----------------------------------------------------------+
| Groups_3 | ref | PRIMARY,Groups1,Groups2 |
Groups1 | 65 | const | 108 | Using
where; Using index; Using temporary; Using filesort |
| CachedGroupMembers_2 | ref | DisGrouMem,GrouMem,MemberId |
GrouMem | 5 | Groups_3.id | 1 | Using
where; Using index |
| Principals_1 | eq_ref | PRIMARY |
PRIMARY | 4 | CachedGroupMembers_2.MemberId | 1 | Using
where |
| ACL_4 | range | ACL1 |
ACL1 | 50 | NULL | 36 | Using
where; Using index |
| main | eq_ref | PRIMARY,Users3 |
PRIMARY | 4 | Principals_1.id | 1
| |
+----------------------+--------+-----------------------------
+---------+---------+-------------------------------+------
+-----------------------------------------------------------+
You'll note that it's starting on the Groups table rather than the
Users table, which I suspect is a lot less expensive (and yes, we have
a smaller RT database than you)
I sort of wonder whether that "member1" key is causing your RT to make
a bad call about join ordering.
