[jira] [Commented] (TINKERPOP-1336) normSack doesn't work in OLAP

["Marko A. Rodriguez (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TINKERPOP-1336?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15325908#comment-15325908 ] 

Marko A. Rodriguez commented on TINKERPOP-1336:
-----------------------------------------------

This is a known problem related to sideEffects (and thus, sack operators) being transient in OLAP. There is another ticket on this and there is a big TODO in the codebase as well as that these tests in the {{ProcessXXXSuite}} are {{@IgnoreEngine}}.

> When {{normSack}} is used in OLAP query, all sack values become the same. Maybe that's "expected"..? But then it should be mentioned in the docs.
