The core API of the driver, that deals with query execution and cluster metadata.

Interface Summary

Interface	Description
AsyncAutoCloseable	An object that can be closed in an asynchronous, non-blocking manner.
AsyncPagingIterable<ElementT,SelfT extends AsyncPagingIterable<ElementT,SelfT>>	An iterable of elements which are fetched asynchronously by the driver, possibly in multiple requests.
ConsistencyLevel	The consistency level of a request.
CqlSession	The default session type built by the driver.
MappedAsyncPagingIterable<ElementT>	The result of calling AsyncPagingIterable.map(Function) on another async iterable.
MavenCoordinates
PagingIterable<ElementT>	An iterable of elements which are fetched synchronously by the driver, possibly in multiple requests.
ProtocolVersion	A version of the native protocol used by the driver to communicate with the server.

Class Summary

Class	Description
CqlIdentifier	The identifier of CQL element (keyspace, table, column, etc).
CqlSessionBuilder	Helper class to build a CqlSession instance.
DriverTimeoutException.NodeDiagnostics	Per-node diagnostic snapshot captured at timeout time.
Version	A structured version number.

Enum Summary

Enum	Description
CQL4SkipMetadataResolveMethod
DefaultConsistencyLevel	A default consistency level supported by the driver out of the box.
DefaultProtocolVersion	A protocol version supported by default by the driver.
RequestRoutingType	The type of routing for a given request.

Exception Summary

Exception	Description
AllNodesFailedException	Thrown when a query failed on all the coordinators it was tried on.
DriverException	Base class for all exceptions thrown by the driver.
DriverExecutionException	Thrown by synchronous wrapper methods (such as SyncCqlSession.execute(Statement), when the underlying future was completed with a checked exception.
DriverTimeoutException	Thrown when a driver request timed out.
InvalidKeyspaceException	Thrown when a session gets created with an invalid keyspace.
NodeUnavailableException	Indicates that a Node was selected in a query plan, but it had no connection available.
NoNodeAvailableException	Specialization of AllNodesFailedException when no coordinators were tried.
RequestThrottlingException	Thrown if the session uses a request throttler, and it didn't allow the current request to execute.
UnsupportedProtocolVersionException	Indicates that we've attempted to connect to a Cassandra node with a protocol version that it cannot handle (e.g., connecting to a C* 2.1 node with protocol version 4).
