Class DelegatingAuroraConnection

java.lang.Object

org.threadly.db.AbstractDelegatingConnection

org.threadly.db.aurora.DelegatingAuroraConnection

All Implemented Interfaces:

java.lang.AutoCloseable, java.sql.Connection, java.sql.Wrapper

public class DelegatingAuroraConnection
extends AbstractDelegatingConnection
implements java.sql.Connection

Implementation of Connection which under the hood delegates to one of several connections to an Aurora server. This uses the AuroraClusterMonitor to monitor the provided cluster, and intelligently choose which connection to delegate to.

From an external perspective this is just a single connection doing some magic to fairly distribute load if possible, and to handle fail over conditions with minimal impact.
