------------------------------------
Summary: CatalogManager#createTable and createTemporaryTable
should provide consistent semantics
Key: FLINK-17067
URL: https://issues.apache.org/jira/browse/FLINK-17067
Project: Flink
Issue Type: Improvement
Components: Table SQL / API
Affects Versions: 1.10.0
Reporter: Zhenghua Gao
Fix For: 1.11.0
Currently CatalogManager#createTable provides [IF NOT EXISTS] semantic and
CatalogManager#createTemporaryTable provides [OR REPLACE] semantic. IMO they
should provide consistent semantics: [IF NOT EXISTS] or [OR REPLACE] or BOTH.
I prefer [IF NOT EXISTS] since we didn't support [OR REPLACE] in table DDL(and
view DDL) currently.
