DFEGroupByHashIndex – This is a blocking operation that organizes the rows of a relation according to a set of variables, outputting a single group identifier column that is one-to-one with the rows of the input relation. Groups here are defined by the join variables used to build the has...
This is how many blocks you processed in "consistent read" mode. This will include counts of blocks read from the rollback segment in order to roll back a block. This is the mode you read blocks in with a SELECT, for example. Also, when you do a searched UPDATE/DELETE, you read the...

The optimizer determined 1) that at mostone row should be returned, and 2) that to produce this row, a deterministicset of rows must be read. When the rows to be read can be read during theoptimization phase (for example, by reading index rows), there is no need toread any tables du...
