We've expected that it would be hard to understand all the aspects at first
so created an explanation for it.
Please see the following readme which hopefully answers most of your
questions:

I don't quite understand, it's an abstraction over lots of concrete

The only example I saw in the Spark distribution was
ExampleJdbcConnectionProvider file in the examples directory. It

reader and writer, why such provider
There are 8 concrete implementations of it? OracleConnectionProvider, etc
