---------------------------------------
Summary: Support DSv2 Join pushdown for DB2 connector
Key: SPARK-59030
URL: https://issues.apache.org/jira/browse/SPARK-59030
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 4.3.0
Reporter: Shrirang Mhalgi
Join pushdown was introduced in SPARK-52187 and is enabled for Oracle
(SPARK-52823), PostgreSQL (SPARK-52906), and MySQL/MSSQL (SPARK-52929). DB2 was
not included in that batch.
DB2 supports ANSI standard join syntax (INNER, LEFT/RIGHT/FULL OUTER, CROSS)
and can handle pushed-down joins using the shared
{{JdbcSQLQueryBuilder.withJoin()}} framework without any dialect-specific SQL
generation.
This Jira adds join pushdown for DB2.
