Eyal Allweil updated DATAFU-114:
--------------------------------
Attachment: FirstTupleFromBag.java
I wasn't able to test this patch because I can't get the build working on my
system (Ubuntu LTS) .. I'm getting the error described
[here|https://issues.apache.org/jira/browse/DATAFU-95]. I can't seem to make
Gradle use a different Java to get it to compile.
However, since the implementation of Accumulator is relatively straightforward,
I hopefully haven't made any mistakes and I would appreciate if someone whose
build is working tried it out and pulled the patch.
> Make FirstTupleFromBag implement Accumulator
> --------------------------------------------

> Key: DATAFU-114
> URL: https://issues.apache.org/jira/browse/DATAFU-114
> Project: DataFu
> Issue Type: Improvement
> Affects Versions: 1.3.0
> Environment: All
> Reporter: Eyal Allweil
> Priority: Minor
> Labels: easyfix, newbie, performance
> Attachments: FirstTupleFromBag.java
>
>
> FirstTupleFromBag only needs the first tuple from the bag, but because it
> doesn't implement Accumulator the entire bag needs to be passed to it
> in-memory. The fix is very minor and will make the UDF support large bags.
