Subject Re: Query Execution Error when changing the cache from PARTITIONED to REPLICATED
Date Mon, 11 Dec 2017 14:36:00 GMT
Hello,

I see in attached files the following "Caused by:
java.lang.OutOfMemoryError: Java heap space" error. It means that one node
can't handle whole resultset of this query. You need to increase JVM heap
size (via -Xmx/-Xms vm properties) or add node in cluster. Look at the
following doc pages:

1. https://apacheignite.readme.io/docs/preparing-for-production
2. https://apacheignite.readme.io/docs#garbage-collection-tuning
