-----------------------------------------
[~vkulichenko], we almost reached code freeze for AI 2.7. Will you be able to
complete it by 30 Sept 2018?
> Add joins to Spark Dataframe examples
> -------------------------------------
>
> Key: IGNITE-9732
> URL: https://issues.apache.org/jira/browse/IGNITE-9732
> Project: Ignite
> Issue Type: Improvement
> Components: examples, spark
> Affects Versions: 2.6
> Reporter: Valentin Kulichenko
> Priority: Major
> Fix For: 2.7
>
>
> {{IgniteDataFrameExample}} creates two tables - {{city}} and {{person}}, but
> only {{person}} is actually used. Need to add join examples.
> Would also be great to demonstrate the fact that optimization is working and
> joins are executed in Ignite, not Spark (using {{explain()}}, maybe?).
