Terry Kim created SPARK-45784:
---------------------------------
Summary: Introduce clustering mechanism to Spark
Key: SPARK-45784
URL: https://issues.apache.org/jira/browse/SPARK-45784
Project: Spark
Issue Type: New Feature
Components: SQL
Affects Versions: 4.0.0
Reporter: Terry Kim
This proposes to introduce CLUSTER BY clause to CREATE/REPLACE SQL syntax:
{code:java}
CREATE TABLE tbl(a int, b string) CLUSTER BY (a, b){code}
There will not be an implementation, but it's up to the catalog implementation
to utilize the clustering information (e.g., Delta, Iceberg, etc.).
Note that specifying CLUSTER BY will throw an exception if the table being
created is for v1 source or session catalog (e.g., v2 source w/ session
catalog).
