Class RestRequest

java.lang.Object

net.snowflake.client.jdbc.RestRequest

public class RestRequest
extends Object

This is an abstraction on top of http client.

Currently it only has one method for retrying http request execution so that the same logic doesn't have to be replicated at difference places where retry is needed.
