[jira] [Updated] (MADLIB-1039) Pivoting - Phase 3
[ https://issues.apache.org/jira/browse/MADLIB-1039?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Frank McQuillan updated MADLIB-1039:
------------------------------------
Description:
Follow on to these JIRAs
https://issues.apache.org/jira/browse/MADLIB-908
https://issues.apache.org/jira/browse/MADLIB-1004
this capability is to carry over some good ideas from
https://issues.apache.org/jira/browse/MADLIB-1038
Candidate improvements:
* output column naming options
* adding an ‘*’ option and list of features to exclude
* pivot more than 1600 column limit, i.e., most MADlib algos take array input so pivot should support array output
* Support non-STRICT functions in Greenplum and HAWQ; this was removed in 1.9.1 since it is not handled correctly. Does work OK for Postgres.
* others???
