In this podcast, Sam Ramji of DataStax discusses how GRPC and Cassandra can optimize performance in distributed systems. He explains that consistency is a major concern when dealing with distributed systems, and the CAP theorem plays an important role in understanding the trade-offs between consistency and availability. The panel also talks about the value of open source projects like Stargate, which aims to provide a data gateway for modern data applications. They emphasize the importance of reducing developer and operator toil by automating certain tasks and letting robots do the work. ```
