Aljoscha Krettek closed FLINK-4205.
-----------------------------------
Resolution: Abandoned
I'm closing this as "Abandoned", since there is no more activity and the code
base has moved on quite a bit. Please re-open this if you feel otherwise and
work should continue.
> Implement stratified sampling for DataSet
> -----------------------------------------
>
> Key: FLINK-4205
> URL: https://issues.apache.org/jira/browse/FLINK-4205
> Project: Flink
> Issue Type: New Feature
> Components: API / DataSet
> Reporter: Do Le Quoc
> Priority: Major
>
> Since a Dataset might consist of data from disparate sources. As such, every
> data source should be considered fairly to have a representative sample. For
> this, stratified sampling is needed to ensure that data from every source
> (stratum) is selected and none of the minorities are excluded.
