[jira] [Updated] (FLINK-19494) Adjust
"StreamExecutionEnvironment.generateSequence()" to new API Sources
[ https://issues.apache.org/jira/browse/FLINK-19494?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Nicholas Jiang updated FLINK-19494:
-----------------------------------
Description:
The utility method {{StreamExecutionEnvironment.generateSequence(()}} should instantiate the new {{NumberSequenceSource}} rather than the existing {{StatefulSequenceSource}}.
We should also deprecate the {{StatefulSequenceSource}} as part of this change, because
- it is based on the legacy source API
- it is not scalable, because it materializes the sequence
