------------------------------------
Summary: Avoid creating temporary tables for inline tables
Key: FLINK-25609
URL: https://issues.apache.org/jira/browse/FLINK-25609
Project: Flink
Issue Type: Sub-task
Components: Table SQL / API
Reporter: Timo Walther
Currently, inline tables such as {{fromDataStream}} or
{{from(TableDescriptor)}} as well as {{toChangelogStream}} or
{{Table.executeInsert(TableDescriptor)}} create an artifical temporary table
with object identifier.
This is due to Calcite that forces {{RelBuilder.scan}} to have an object
identifier.
Instead we should:
- Create an internal {{RelOptTable}} that wraps {{CatalogTable}}
- Various flavors of {{CatalogTable}} can store the {{DataStream}} object or
information of the {{TableDescriptor.}}
