Amareshwari Sriramadasu created LENS-909:
--------------------------------------------
Summary: We should avoid sending email notification with inmemory
results
Key: LENS-909
URL: https://issues.apache.org/jira/browse/LENS-909
Project: Apache Lens
Issue Type: Improvement
Components: server
Reporter: Amareshwari Sriramadasu
Assignee: Sushil Mohanty
Fix For: 2.5
Right now, when result is not persisted , result will be available in memory.
And user would fetch the results inmemory.
With email notification being sent, only of them will be able to fetch results.
If email notifier already reads the results, then client cannot fetch and vice
versa.
