UR::DataSource::RDBMS::BitmapIndex(3pm)

NAME
UR::DataSource::RDBMS::BitmapIndex - metadata about a data source's bitmap indexes

DESCRIPTION
This class represents instances of bitmap indexes in a data source. They are maintained by 'ur update classes' and stored in the namespace's MetaDB.

The existence of bitmap indexes in a datasource affects SQL generation during a Context commit. Oracle's implementation requires a table covered by a bitmap index to be locked while it is being updated.
