Feature: Sessionize funtion - Phase 2
JIRA: MADLIB-1001
This contains the phase 2 implementation of the sessionize function.
This commit adds two new optional parameters: output_cols and
create_view. output_cols is a comma separated list of columns to
be projected into the output, while create_view indicates if the
output is a view or a table. The default values of output_cols
and create_view are '*' and True respectively.
These two parameters are for performance reasons. A view is
generally faster when compared to materializing the results to an
actual table, while having to include all columns when not necessary
can be avoided with the output_cols parameter.
