Hi guys, I am trying to test a job that should run a number of tasks to read from a RDBMS using an improved JDBC connector. The connection and the reading run smoothly, but I cannot seem to be able to move above the limit of 8 concurrent threads running. 8 is of course the number of cores of my machine.
I have tried working around configurations and settings, but the Executor within the ExecutionContext keeps on having a parallelism of 8. Although, of course, the parallelism of the execution environment is much higher (in fact I have many more tasks to be allocated). I feel it may be an issue of the LocalMiniCluster configuration that may just override/neglect my wish for higher degree of parallelism. Is there a way for me to work around this issue? please let me know. Thanks a lot for you help! :-) saluti, Stefano
