Puneet Gupta created LENS-978:
---------------------------------
Summary: Default value of "lens.client.query.poll.interval" is
very small
Key: LENS-978
URL: https://issues.apache.org/jira/browse/LENS-978
Project: Apache Lens
Issue Type: Improvement
Reporter: Puneet Gupta
Assignee: Puneet Gupta
Priority: Trivial
The poll interval is kept at 10 ms as of now . This causes excessive polling
on the server (as most clients do not set the property to an optimum value).
One use case for such small value could be in a case where user wants
realtime/interactive response for queries that spend very small time in
execution. But in this case the user has better options available in form of
"EXECUTE_WITH_TIMEOUT" rather than using async query execution followed by
continuous polling for state.
Further the EXECUTE_WITH_TIMEOUT will also be made available on CLI (which was
not the case earlier) via LENS-915
Propose to increase the value to 5 secs ( for specific use cases, users can
override this value if required)
