Hi Roman, Actually it does not work as I expect it. Please see https://github.com/hostettler/igniteParallelQueries Do mvn clean install and then java -jar target/ignite-parallel-query-1.0.0-SNAPSHOT-jar-with-dependencies.jar
This demonstrates that with or without the flag the query does not return the same result. I understand that it probably because I did not set an affinity but it is very counter-intuitive. Am I missing something? -----Original Message----- From: Roman Kondakov <kondako...@mail.ru.INVALID> Sent: Friday, November 15, 2019 11:46 AM To: dev@ignite.apache.org Subject: Re: New SQL execution engine Hi Steve, it is possible to execute queries in parallel even in the current engine, see docs here [1]. And of course this feature should also be available in the new engine, though it's architecture may be changed.
