Encoded vector index scan icon

Encoded Vector Index Scan

The Encoded Vector Index Scan icon indicates that the entire encoded vector index will be scanned causing all of the distinct values represented in the index to be processed. Any selection criteria, whose predicates match the key columns of the encoded vector index, can then be applied against the distinct values represented in the index. Only those distinct values that match the specified key selection will then be used to process the vector and generate either a temporary row number list or temporary row number bitmap.
