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.
