Jark Wu commented on FLINK-6966: -------------------------------- The key problem is how to generate a deterministic UID for the same query. We can learn from {{StreamGraphHasherV1#generateDeterministicHash}} which generates the default UID for operators. What should we take into account to generate the UID? The aggs, the window types? > Add maxParallelism and UIDs to all operators generated by the Table API / SQL > ----------------------------------------------------------------------------- > > Key: FLINK-6966 > URL: https://issues.apache.org/jira/browse/FLINK-6966 > Project: Flink > Issue Type: Improvement > Components: Table API & SQL > Affects Versions: 1.4.0 > Reporter: Fabian Hueske > Assignee: sunjincheng > > At the moment, the Table API does not assign UIDs and the max parallelism to > operators (except for operators with parallelism 1). > We should do that to avoid problems when rescaling or restarting jobs from > savepoints. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
