Github user decibel commented on the pull request: https://github.com/apache/incubator-madlib/pull/44 Has consideration been given to allowing for the creation of a view instead of a table? If you only needed session info once, or only for a subset of values in the input table, that could be significantly faster than materializing it. Related to that... it could also be faster to only materialize the partition columns, series number and timespan for each series. You would need to join the base data against that, but in some cases it could be faster. A variation on this would be to specify the exact columns you want materialized. So perhaps add "create_view = False, materialize_columns = None" parameters, where materialize_columns == None means materialize the whole shebang, while materialize_columns = [] means only materialize the partition clause, session and timestamp.
