------------------------------
Summary: What's the progress of vectorized execution for spark?
Key: SPARK-37034
URL: https://issues.apache.org/jira/browse/SPARK-37034
Project: Spark
Issue Type: New Feature
Components: Spark Core
Affects Versions: 3.2.0
Reporter: xiaoli
Spark has support vectorized read for ORC and parquet. What's the progress of
other vectorized execution, e.g. vectorized write, join, aggr, simple operator
(string function, math function)?
Hive support vectorized execution in [early
version|[https://cwiki.apache.org/confluence/display/hive/vectorized+query+execution]|https://cwiki.apache.org/confluence/display/hive/vectorized+query+execution].]
As we know, Spark is replacement of Hive. I guess the reason why Spark does
not support vectorized execution maybe the difficulty of design or
implementation in Spark is larger. What's the main issue for Spark to support
vectorized execution?
