-------------------------------------
Summary: Support same timeout operations in mapGroupsWithState
function in batch queries as in streaming queries
Key: SPARK-20792
URL: https://issues.apache.org/jira/browse/SPARK-20792
Project: Spark
Issue Type: Sub-task
Components: Structured Streaming
Affects Versions: 2.2.0
Reporter: Tathagata Das
Assignee: Tathagata Das
Currently, in the batch queries, timeout is disabled (i.e.
GroupStateTimeout.NoTimeout) which means any GroupState.setTimeout*** operation
would throw UnsupportedOperationException. This makes it weird when converting
a streaming query into a batch query by changing the input DF from streaming to
a batch DF. If the timeout was enabled and used, then the batch query will
start throwing UnsupportedOperationException.
