Zhenghua Gao commented on FLINK-17067:
--------------------------------------
Seems we didn't expose [OR REPLACE] out yet.
Most invoking of CatalogManager#createTemporaryTable use "[OR REPLACE] =
false", which is compatible with "[IF NOT EXISTS] = false".
The only two exceptions are TableEnvironmentImpl#registerTableSourceInternal()
and TableEnvironmentImpl#registerTableSinkInternal() which are called in
deprecated APIs (registerTableSource/Sink).
> CatalogManager#createTable and createTemporaryTable should provide consistent
> semantics

> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / API
> Affects Versions: 1.10.0
> Reporter: Zhenghua Gao
> Priority: Major
> 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].
> I prefer [IF NOT EXISTS] since we didn't support [OR REPLACE] in table
> DDL(and view DDL) currently.
