public interface ClientManager

Client represents a connection to a database, cache, or API endpoint. The Client might send requests to an external datastore like MySQL or it might contain an in-memory datastructure like a cache namespace that contains individual caches for each Node. A Client must know the location of its backing datastore and any authentication information. It will manage connections to the datastore and usually contains a connection pool. Connecting over the network to external datastores is the slowest part of Datarouter startup. JDBC necessitates that connections are assigned to a single "schema" in an RDBMS. Because we want to pool these connections, we create one Client per database, even though many databases may reside in the same MySQL instance.
