------------------------------
Summary: Vectorization: BytesBytes lookup capped count can be =0,
=1, >=2
Key: HIVE-14434
URL: https://issues.apache.org/jira/browse/HIVE-14434
Project: Hive
Issue Type: Improvement
Components: Vectorization
Affects Versions: 2.2.0
Reporter: Gopal V
Assignee: Gopal V
BytesBytesHashmap does not implement deep counters for the depth of a probe -
but however it does distinguish between 0, 1 and > 1 rows.
This information can be used in the vectorized hash join to avoid copying the
probe side keys.
