As the amount of data grows, the need for efficient data compression becomes increasingly important to save storage space, reduce I/O overhead, and improve query performance. Block compression can improve performance by allowing data to be read and written in smaller chunks. Snappy is a compression library developed by Google.

Sometimes developers only care about speed. Some will claim that any type of RPC communication ends up being faster (meaning it has lower latency) than any equivalent invocation using asynchronous messaging. It’s less of an apples-to-oranges comparison and more like apples-to-orange-sherbet. So we’ll just use “RPC” for short.
