Abstract
Techniques are provided for maintaining and using row-level and column-level invalidation information for a copy of data items stored in-memory via a row-bitmap and column-bitmap. The row-bitmap and column-bitmap can be used to determine whether a database query can be processed using in-memory data or not. The row-bitmap and column-bitmap can thus improve the frequency with which database queries can be processed using in-memory data.
