Reynold Xin commented on SPARK-6624: ------------------------------------ [~cloud_fan] interested in doing this one also? > Convert filters into CNF for data sources > ----------------------------------------- > > Key: SPARK-6624 > URL: https://issues.apache.org/jira/browse/SPARK-6624 > Project: Spark > Issue Type: Sub-task > Components: SQL > Reporter: Reynold Xin > > We should turn filters into conjunctive normal form (CNF) before we pass them > to data sources. Otherwise, filters are not very useful if there is a single > filter with a bunch of ORs. > Note that we already try to do some of these in BooleanSimplification, but I > think we should just formalize it to use CNF. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
