Subject Re: Full table scan query by ODBC causing node shutdown
Date Wed, 27 Sep 2017 15:37:45 GMT
CacheConfiguration.queryParallelism parameter affects all queries which
perform under this cache. It doesn't matter which API you will use. I guess
that when you increase heap size and tune gc it will bring significant
performance improvement for the case.
