> URL: https://issues.apache.org/jira/browse/IGNITE-9732
> Project: Ignite
> Issue Type: Improvement
> Components: examples, spark
> Affects Versions: 2.6
> Reporter: Valentin Kulichenko
> Assignee: Aleksey Zinoviev
> Priority: Major
> Fix For: 2.8

> {{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?).
