Hi,

Can any one help me out in understanding the below terminology of the EXPLAIN plan

"sliding-window merge join (contexts = 1, 16)"


What kind of join makes the above sense? Is it a SI-SI join or any other combination of index? How the performance will be with such a kind of join?


Thanks a lot in Advance.
