Fabian Hueske updated FLINK-7548: --------------------------------- Priority: Blocker (was: Major) > Support watermark generation for TableSource > -------------------------------------------- > > Key: FLINK-7548 > URL: https://issues.apache.org/jira/browse/FLINK-7548 > Project: Flink > Issue Type: Bug > Components: Table API & SQL > Reporter: Jark Wu > Assignee: Fabian Hueske > Priority: Blocker > > As discussed in FLINK-7446, currently the TableSource only support to define > rowtime field, but not support to extract watermarks from the rowtime field. > We can provide a new interface called {{DefinedWatermark}}, which has two > methods {{getRowtimeAttribute}} (can only be an existing field) and > {{getWatermarkGenerator}}. The {{DefinedRowtimeAttribute}} will be marked > deprecated. > How to support periodic and punctuated watermarks and support some built-in > strategies needs further discussion. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
