SingleStore and TDV: Make queries on tables that are on different databases but on the same SingleStore cluster run in push down

Use or support Zing JVM for better GC and server performance

We currently use large heap sizes >16gb and running into frequent client timeout issues caused by "Long GC pauses". We tried jvm fine-tuning with CMS and G1 GC. Other JVMs such as Azul's Zing/Zulu JVM would help in this case with true parallel ...
