Highlights of Recent PR ​

A simple REPL for debugging purpose ​

Before removing SQL interface from Datanode, we need something as a substitute to mysql-cli. This REPL can serve the purpose. It's largely inspired by InfluxDB IOx . Simple, yet powerful, has history and hints, and can directly execute SQL via our grpc interface. Here is a screenshot:

Add memory profiling ​

Add memory profiling feature and HTTP handler to dump profiling data.

Support COPY FROM statement ​

COPY FROM is used to import data from a file into a table. Before this, we supported the COPY TO statement, when combined, could accomplish both data export and import.
