[jira] [Commented] (HAWQ-453) Do not allocate query resource in prepare stage for prepared statement

    [ https://issues.apache.org/jira/browse/HAWQ-453?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15166922#comment-15166922 ] 

Ruilong Huo commented on HAWQ-453:
----------------------------------

The resolution is:
1. In SPI prepare, we generate plan, get and save query resource parameters
2. In SPI execute, we allocate query resource according to saved query resource parameters, and allocate datalocality

> Do not allocate query resource in prepare stage for prepared statement
