Ok, I'll try increasing the heap size. One more question here, from the log it says the full table scan query is taking 30s. And I wonder is there any way to speed the query up? I found this article https://apacheignite.readme.io/v2.2/docs/sql-performance-and-debugging#section-query-parallelism
And my question is if I set CacheConfiguration.queryParallelism parameter when I ingest the data, will it take effect when I query the data by ODBC? Or is it only effective querying the data by Java API with CacheConfiguration.queryParallelism specified? Thanks -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
