Enzo Mar commented on MADLIB-1028:
----------------------------------
I think a good use case for madlib could be for clickstream analysis: too much
data to keep in memory.
Hence it is a good idea to beef up all functionalities around clickstream
analysis (e.g. I'm going to report a bug on apriori related to this).
I haven't used the Aster functionality directly, but it seems interesting to be
able to spot automatic clicking etc.
As a side note, to do a sessionization in sql, thanks to window functions, is
not that difficult (and there are examples on the web). Starting to add
features like rapid_fire is more complex...

> Key: MADLIB-1028
> URL: https://issues.apache.org/jira/browse/MADLIB-1028
> Project: Apache MADlib
> Issue Type: Improvement
> Components: Module: Utilities
> Reporter: Enzo Mar
> Priority: Minor
>
> The recent implementation of sessionization could benefit from adding a
> "rapid_fire" field (a sort of min_filed in comparison to the existing
> max_field).
> Aster Data implementation of sessionization has this field.
> Basically it is used to flag and potentially exclude events too close to each
> other. This helps to detect / eliminate either errors or robotic type of
> access.
> To see it in action have a look at the Aster video on sessionize:
