Kurt Young closed FLINK-8045. ----------------------------- Resolution: Unresolved > 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 > Priority: Major > Labels: pull-request-available > Time Spent: 10m > Remaining Estimate: 0h > > 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) -- This message was sent by Atlassian JIRA (v7.6.3#76005)
