Eugene Koifman created HIVE-14947: ------------------------------------- Summary: Add support for Acid 2 in Merge Key: HIVE-14947 URL: https://issues.apache.org/jira/browse/HIVE-14947 Project: Hive Issue Type: Sub-task Components: Transactions Reporter: Eugene Koifman Assignee: Eugene Koifman
HIVE-14035 etc introduced a more efficient data layout for acid tables Additional work is needed to support Merge for these tables Need to make sure we generate unique ROW__IDs in each branch of the multi-insert statement. StatementId was introduced in HIVE-11030 but it's not surfaced from storage layer. It needs to be made part of ROW__ID to ensure unique ROW__ID from concurrent writes from the same query. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
