BootstrappingException	Indicates that the contacted host was bootstrapping when it received a read query.
BusyConnectionException	Indicates that a connection has run out of stream IDs.
BusyPoolException	Indicates that a connection pool has run out of available connections.

FunctionExecutionException	Error during the execution of a function.
InvalidConfigurationInQueryException	A specific invalid query exception that indicates that the query is invalid because of some configuration problem.
InvalidQueryException	Indicates a syntactically correct but invalid query.
InvalidTypeException	Thrown when a TypeCodec is unable to perform the requested operation (serialization, deserialization, parsing or formatting) because the object or the byte buffer content being processed does not comply with the expected Java and/or CQL type.
NoHostAvailableException	Exception thrown when a query cannot be performed because no host is available.
OperationTimedOutException	Thrown on a client-side timeout, i.e. when the client didn't hear back from the server within SocketOptions.getReadTimeoutMillis().
OverloadedException	Indicates that the contacted host reported itself being overloaded.
PagingStateException	Indicates an error while deserializing a (previously serialized) PagingState object, or when a paging state does not match the statement being executed.
ProtocolError	Indicates that the contacted host reported a protocol error.
QueryConsistencyException	A failure to reach the required consistency level during the execution of a query.
QueryExecutionException	Exception related to the execution of a query.
QueryValidationException	An exception indicating that a query cannot be executed because it is syntactically incorrect, invalid, unauthorized or any other reason.
ReadFailureException	A non-timeout error during a read query.
ReadTimeoutException	A Cassandra timeout during a read query.
ServerError	Indicates that the contacted host reported an internal error.
SyntaxError	Indicates a syntax error in a query.
TraceRetrievalException	Exception thrown if a query trace cannot be retrieved.
TransportException	A connection exception that has to do with the transport itself, i.e. that suggests the node is down.

UnresolvedUserTypeException	Thrown when a user type cannot be resolved.
UnsupportedFeatureException	Exception thrown when a feature is not supported by the native protocol currently in use.
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* 1.2 node with protocol version 2).
WriteFailureException	A non-timeout error during a write query.
