class cassandra.pool.Host[source]¶

Represents a single Cassandra node.

is_up = None¶

True if the node is considered up, False if it is considered down, and None if it is not known if the node is up or down.

The IP address of the node. This is the RPC address the driver uses when connecting to the node

conviction_policy = None¶

A ConvictionPolicy instance for determining when this node should be marked up or down.
