Interface Summary

Interface	Description
AsyncInitSession	A Session that can be initialized asynchronously.
Authenticator	Handles SASL authentication with Cassandra servers.
AuthProvider	Provides Authenticator instances for use when connecting to Cassandra nodes.
Cluster.Initializer	Initializer for Cluster instances.
GettableData	Collection of (typed) CQL values that can be retrieved by index (starting at 0), or by name.
Host.StateListener	Interface for listeners that are interested in hosts added, up, down and removed events.
LatencyTracker	Interface for objects that are interested in tracking the latencies of the driver queries to each Cassandra nodes.
PreparedStatement	Represents a prepared statement, a query with bound variables that has been prepared (pre-parsed) by the database.
ResultSet	The result of a query.
ResultSetFuture	A future on a ResultSet.
Row	A CQL Row returned in a ResultSet.
SchemaChangeListener	Interface for objects that are interested in tracking schema change events in the cluster.

Class Summary

Class	Description
AbstractSession	Abstract implementation of the Session interface.
BatchStatement	A statement that group a number of Statement so they get executed as a batch.

CloseFuture	A future on the shutdown of a Cluster or Session instance.
Cluster	Information and known state of a Cassandra cluster.
Cluster.Builder	Helper class to build Cluster instances.
ColumnDefinitions	Metadata describing the columns returned in a ResultSet or a PreparedStatement.
ColumnDefinitions.Definition	A column definition.
ColumnMetadata	Describes a Column.
ColumnMetadata.IndexMetadata	Metadata on a column index.
Configuration	The configuration of the cluster.
DataType	Data types supported by cassandra.
DefaultPreparedStatement
DelegatingCluster	Base class for custom Cluster implementations that wrap another instance (delegate / decorator pattern).
ExecutionInfo	Basic information on the execution of a query.
Host	A Cassandra node.
KeyspaceMetadata	Describes a keyspace defined in this cluster.
Metadata	Keeps metadata on the connected cluster, including known nodes and schema definitions.
Metrics	Metrics exposed by the driver.
MetricsOptions	Metrics options.
NettyOptions	A set of hooks that allow clients to customize the driver's underlying Netty layer.
PagingState	The paging state of a query.
PerHostPercentileTracker	A LatencyTracker that records latencies for each host over a sliding time interval, and exposes an API to retrieve the latency at a given percentile.

QueryLogger.ConstantThresholdQueryLogger	A QueryLogger that uses a constant threshold in milliseconds to track slow queries.
QueryLogger.DynamicThresholdQueryLogger	A QueryLogger that uses a dynamic threshold in milliseconds to track slow queries.
QueryOptions	Options related to defaults for individual queries.
QueryTrace	The Cassandra trace for a query.
QueryTrace.Event	A trace event.
RegularStatement	A regular (non-prepared and non batched) CQL statement.
SimpleStatement	A simple RegularStatement implementation built directly from a query string.
SocketOptions	Options to configure low-level socket options for the connections kept to the Cassandra hosts.
SSLOptions	Options to provide to enable SSL connections.
Statement	An executable query.
StatementWrapper	Base class for custom Statement implementations that wrap another statement.
