-------------------------------------------
Summary: 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
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?).
