Tom Lane 787eba734b When creating a large hash index, pre-sort the index entries by estimated ... bucket number, so as to ensure locality of access to the index during the insertion step. Without this, building an index significantly larger than available RAM takes a very long time because of thrashing. On the other hand, sorting is just useless overhead when the index does fit in RAM. We choose to sort when the initial index size exceeds effective_cache_size. This is a revised version of work by Tom Raney and Shreya Bhargava.		2008-03-16 23:15:08 +00:00
