Hi All, I am new to calcite. I need help to implement an "Exchange operator" in calcite.
I read the Research Paper " Apache Calcite:A Foundational Framework for Optimized Query Processing Over Heterogeneous Data Sources " for a mere understanding of calcite. An Exchange operator basically divides a query into plan fragments which are executed parallelly. I got an minimal estimation of how a query optimizer works in calcite with the help of adapters. I need help to understand how a Query is executed in calcite and If possible can I get a basic implementation idea. Can some body point me to Hello world of Exchange operator. Thanks and Regards, Amey Ladewar.
