----------------------------------
Summary: Build BytesToBytesMap in HashedRelation
Key: SPARK-14052
URL: https://issues.apache.org/jira/browse/SPARK-14052
Project: Spark
Issue Type: Improvement
Components: SQL
Reporter: Davies Liu
Assignee: Davies Liu
Currently, for the key that can not fit within a long, we build a hash map for
UnsafeHashedRelation, it's converted to BytesToBytesMap after serialization and
deserialization.
We should build a BytesToBytesMap directly to have better memory efficiency.
