-----------------------------------
Summary: Add Internal DATE/TIME/TIMESTAMP as internal
representation of DATE/TIME/TIMESTAMP
Key: FLINK-8045
URL: https://issues.apache.org/jira/browse/FLINK-8045
Project: Flink
Issue Type: Improvement
Components: Table API & SQL
Reporter: Zhenghua Gao
Assignee: Zhenghua Gao
Currently DATE/TIME/TIMESTAMP have internal representation. Such as Date is
represented as Int internal. This feature may improve performance processing
DATE/TIME/TIMESTAMP data. But I found there is a LIMITATION: internal
representation exists only within one operator.
We transfer DATE/TIME/TIMESTAMP objects between operators.
I think we could treat DATE/TIME/TIMESTAMP as internal representation in
the whole job, and cast them to java.sql.* as needed(UDF/UDTF/OUTPUT)
