-----------------------------------------
Summary: normSack doesn't work in OLAP
Key: TINKERPOP-1336
URL: https://issues.apache.org/jira/browse/TINKERPOP-1336
Project: TinkerPop
Issue Type: Bug
Components: process
Affects Versions: 3.2.0-incubating
Reporter: Daniel Kuppitz
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.
