twalthr opened a new pull request #6897: [FLINK-9737] [FLINK-8880] [sql-client]
Support defining temporal tables in environment files
URL: https://github.com/apache/flink/pull/6897
## What is the purpose of the change
This PR introduces the definition of temporal tables also to the SQL Client.
Similar to table views, temporal table definitions need to reference a
different table source or table view. Thus, the definition order is important
which is why this code refactors the parsing of environment files. The recently
introduced top-level section `views` has been integrated into `tables`;
temporal tables are defined there as well. As a side effect of the refactoring,
properties are also validated for data type and value bounds now.
This PR depends on #6893.
## Brief change log
- Additional auxiliary methods for property handling
- Refactoring for similar treatment of table sources, sinks, source-sinks,
views, and temporal tables
- Introduction of a basic validation for all configuration entries
## Verifying this change
- `org.apache.flink.table.client.gateway.local.ExecutionContextTest` has
been extended
- Existing tests have been slightly refactored
