* Used by Routing Driver to decide if a transaction should be routed to a write server or a read server in a cluster.
* When running a transaction, a write transaction requires a server that supports writes.
* A read transaction, on the other hand, requires a server that supports read operations.
* This classification is key for routing driver to route transactions to a cluster correctly.
*
* While any {@link AccessMode} will be ignored while running transactions via a driver towards a single server.
* As the single server serves both read and write operations at the same time.
