Index access using multi-column indices
Started by Hiroshi Inoueover 26 years ago2 messages
Hello all,
Currently,only the first column of multi-column indices
is used to find start scan position of Indexscan-s.
To speed up finding scan start position,I have changed
_bt_first() to use as many keys as possible.
I'll attach the patch here.
Regards.
