[jira] [Updated] (FLINK-24697) Kafka table source cannot change the
auto.offset.reset setting for 'group-offsets' startup mode
[ https://issues.apache.org/jira/browse/FLINK-24697?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Hang Ruan updated FLINK-24697:
------------------------------
Summary: Kafka table source cannot change the auto.offset.reset setting for 'group-offsets' startup mode (was: Kafka table source cannot change the auto.offset.reset setting)
> Kafka table source cannot change the auto.offset.reset setting for 'group-offsets' startup mode

> Issue Type: Improvement

> Because Flink 1.13 SQL does not use the new Source API in FLIP-27, the behavior to start from group offsets in flink 1.13 will use the kafka 'auto.offset.reset' default value(latest), when the 'auto.offset.reset' configuration is not set in table options. But in flink 1.13 we could change the behavior by setting 'auto.offset.reset' to other values. See the method {{setStartFromGroupOffsets in the class FlinkKafkaConsumerBase.}}
> Flink 1.14 uses the new Source API, but we have no ways to change the default 'auto.offset.reset' value when use 'group-offsets' startup mode. In DataStream API, we could change it by `kafkaSourceBuilder.setStartingOffsets(OffsetsInitializer.committedOffsets(OffsetResetStrategy))`.
> So we need the way to change auto offset reset configuration.
> The design is that when 'auto.offset.reset' is set, the 'group-offsets' startup mode will use the provided auto offset reset strategy, or else 'none' reset strategy in order to be consistent with the DataStream API.
