Subject Re: Downsides of Spark-Ignite for extended cache management and access?
Date Wed, 25 May 2016 13:11:21 GMT
Hi,

IgniteRDD is useful when you already have a Spark application and want to
use Ignite as an underlying storage to share the state between different
Spark jobs (which is not possible with plain Spark) and to get advantage of
fast indexed SQL queries provided by Ignite (there are no indexes in Spark).

IgniteRDD provides full RDD API, but cache API is limited. For example, it
doesn't expose transactions. If you're creating an application from scratch,
I would recommend to use Ignite API directly with all its features (cache,
compute, streaming, etc.).

Makes sense?
