--------------------------------------
Summary: CLONE - Path - multiple symbol matches per row
Key: MADLIB-995
URL: https://issues.apache.org/jira/browse/MADLIB-995
Project: Apache MADlib
Issue Type: New Feature
Components: Module: Utilities
Reporter: Frank McQuillan
Fix For: v1.9.1
Story
As a data scientist, I want to be able to define multiple symbols per row for
pattern matching.
See
http://madlib.incubator.apache.org/docs/latest/group__grp__path.html
for a description of what a symbol is.
Currently in 1.9, a given row can only match one symbol. If a row matches
multiple symbols, the symbol that comes first in the symbol definition list
will take precedence. This story is about all matching symbols on a row being
used.
Acceptance
The attached data set and query should should produce the following output:
Event Timestamp User ID Age Group Income Group Gender Region
Household Size Click Event Purchase Event Revenue Margin
4/16/12 5:59 102871 3 4 Female Central 5 1 0
0 0
4/16/12 9:35 102871 3 4 Female Central 5 1 0
0 0
There are symbol matches for:
Gender=Female
Region=Central
Click Event=1
