Sean Owen commented on SPARK-20203:
-----------------------------------
There's no value in splitting the conversation since it's about exactly the
same question. This retained no context about the performance question, for
example, which is the central issue.
> Change default maxPatternLength value to Int.MaxValue in PrefixSpan
> -------------------------------------------------------------------
>
> Key: SPARK-20203
> URL: https://issues.apache.org/jira/browse/SPARK-20203
> Project: Spark
> Issue Type: Wish
> Components: MLlib
> Affects Versions: 2.1.0
> Reporter: Cyril de Vogelaere
> Priority: Trivial
> Original Estimate: 0h
> Remaining Estimate: 0h
>
> I think changing the default value to Int.MaxValue would be more user
> friendly. At least for new users.
> Personally, when I run an algorithm, I expect it to find all solution by
> default. And a limited number of them, when I set the parameters to do so.
> The current implementation limit the length of solution patterns to 10.
> Thus preventing all solution to be printed when running slightly large
> datasets.
> I feel like that should be changed, but since this would change the default
> behavior of PrefixSpan. I think asking for the communities opinion should
> come first. So, what do you think ?
