Biao Ma commented on IGNITE-2538:
---------------------------------
Like blow?
override def isEmpty(): Boolean = {
val cache = ensureCache()
return cache.size() <= 0
}
If my understanding is not biased, I' ll have a try.
> RDD.isEmpty method should be overriden in IgniteRDD to use IgniteCache API

> Currently calling {{IgniteRDD.isEmpty}} ends up in execution of 1024 Spark
> jobs, which is not fast. We should override this method and use native
> {{IgniteCache}} API there. Other methods should be also revisited.
