Summary: SPIP: Support MERGE in Data Source V2 Key: SPARK-35801 URL: https://issues.apache.org/jira/browse/SPARK-35801 Project: Spark Issue Type: Improvement Components: SQL Affects Versions: 3.2.0 Reporter: Anton Okolnychyi [MERGE INTO|https://en.wikipedia.org/wiki/Merge_(SQL)] is well suited to large-scale workloads because it can express operations to insert, update, or delete multiple rows in a single SQL command. Many updates can be expressed as MERGE INTO queries that would otherwise require much more SQL. Common patterns for updating partitions are to read, union, and overwrite or read, diff, and append. Using MERGE INTO, these operations are easier to express and can be more efficient to run. Hive supports [MERGE INTO|https://blog.cloudera.com/update-hive-tables-easy-way/] and Spark should implement similar support. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
