Hi @ahid_002 ,
we also ran into an Out of Memory error (heap space) within our team with a similar setup (K8s). We addressed this issue in Retry for RDB Stream Transformer - #2 by capchriscap and Snowplow team is currently investigating. But I am pretty happy that we are not the only ones facing this issue 
We also have the heap space error within our Enricher v3.2.x, do you face there the same issue?
