    [ https://issues.apache.org/jira/browse/PHOENIX-5238?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16825714#comment-16825714 ] 

Karan Mehta commented on PHOENIX-5238:
--------------------------------------

[~swaroopa] [~neha.gupta] [~yanxinyi] useful to pickup. Some of our internal use cases fetch bulk records using phoenix-spark and this is impactful. HBase block cache is a precious resource.

> As a Spark developer, I want to query with NO_CACHE hint using PhoenixRDD, so I can prevent large one-time scans from affecting the block cache.
