Frank McQuillan updated MADLIB-973:
-----------------------------------
Description:
Story
As a user, I want to be able to define aggregates on pattern matches, so that I
can derive useful information from the patterns that I am interested in.
In addition, I want to be able to do richer subsequent queries on the pattern
matches, so I want need match_id and symbol added to the output table of
matched tuples.
Other:
1) This a progression from these stores
https://issues.apache.org/jira/browse/MADLIB-916
https://issues.apache.org/jira/browse/MADLIB-917
https://issues.apache.org/jira/browse/MADLIB-931
which were doing aggregates on partitions as opposed to pattern matches.
Sample data set(s) for acceptance to be added.

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) Limited to 1 match 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) Support multiple windows per partition.

> Path - make aggregate computation per pattern match (not per partition)
