Class BulkTableScanResultSet

  • All Implemented Interfaces:
    java.lang.Cloneable, CursorResultSet, NoPutResultSet, ResultSet, RowLocationRetRowSource, RowSource

    class BulkTableScanResultSet
    extends TableScanResultSet
    implements CursorResultSet
    Read a base table or index in bulk. Most of the work for this method is inherited from TableScanResultSet. This class overrides getNextRowCore (and extends re/openCore) to use a row array and fetch rows from the Store in bulk (using fetchNextGroup).

    Since it retrieves rows in bulk, locking is not as is usual -- locks may have already been released on rows as they are returned to the user. Hence, this ResultSet is not suitable for a query running Isolation Level 1, cursor stability.

    Note that this code is only accessable from an optimizer override. If it makes sense to have the optimizer select bulk reads, then this should probably be rolled into TableScanResultSet.
