             Summary: Add Memory gatekeepers for InMemoryResultSet to prevent any OOM on lens server
                 Key: LENS-981
                 URL: https://issues.apache.org/jira/browse/LENS-981
             Project: Apache Lens
          Issue Type: Improvement
            Reporter: Puneet Gupta
            Assignee: Puneet Gupta


In Some cases operations on InMemoryResultSet can result is high memory usage on LensServer 

1. InMemoryResultSet.toQueryResult()  is done for a huge result
2. lens.query.prefetch.inmemory.resultset.rows = Huge Number . 

In both cases we need to have some gate keeping as these features can be accessed/configured by users
