Shawn, If you still need to use the on-heap caching by some reason make sure you enabled an eviction policy: https://apacheignite.readme.io/docs/evictions#section-java-heap-cache <https://apacheignite.readme.io/docs/evictions#section-java-heap-cache>
Otherwise the on-heap cache will grow endlessly. BTW, what kind of OOM you got? It might be off-heap or on-heap caching related.
