Presto connector development 1
One of the very good design decisions Presto designers made is that it's loosely coupled from storages.
Presto is a distributed SQL executor engine, and doesn't manager schema or metadata of tables by itself. It doesn't manage read data from storage by itself. Those businesses are done by plugins called Connector. Presto comes with Hive connector built-in, which connects Hive's metastore and HDFS to Presto.
We can connect any storages into Presto by writing connector plugins.
