Kira,

I also wanted to mention that probably the most obvious way you can gain
performance benefit from Ignite compared to Spark is using indexing for SQL
queries. Last time I checked, spark did not have indexes, so each SQL query
in Spark implies a full scan of the data set. In Ignite you can index a
particular entry field, so a query against this field can be significantly
faster. You can also use indexed entities via IgniteRDD.

Please refer to the following section in documentation:
