Subject [jira] Updated: (CASSANDRA-1614) Only create IColumnIterators for matching sstables
Date Wed, 13 Oct 2010 04:22:33 GMT


Stu Hood updated CASSANDRA-1614:

    Attachment: 0001-Only-create-IColumnIterators-for-matching-sstables-a.patch

Adds factory functions to SSTable*Iterators that perform the filter and index checks and return
null for a miss. Also skips decoding the row key when assertions are disabled.

> We currently perform bloom filter and index checks in the constructor for SSTable*Iterators,
which means that the object gets created even if we miss. Using a factory function for this
step would save object creation time.
