> Story
> As a user, I want to define symbols so that I can define a regular expression of symbols to identify sequences of events that I care about.
> Partition:
> 1) Multiple matches per partition in this story.
> 2) Note that the match in the data might not span the whole partition, that is, that matched rows could just be a subset of the rows in the partition.
> Window:
> 1) Limited to 1 window per partition.
> Other
> 1) Club rows together in the case where there are multiple matches per partition, when doing aggregate/window functions.  E.g., if doing sum of a revenue column, then sum all rows from all matches (as opposed to a separate sum for each match).
