Syntax
public abstract class Batch : Statement, IStatement

Fields

_batchType

Declaration
protected BatchType _batchType
Field Value
Type Description
BatchType

_session

Declaration
protected readonly ISession _session
Field Value
Type Description
ISession

_timestamp

Declaration
protected DateTimeOffset? _timestamp
Field Value
Type Description
DateTimeOffset?

Properties

IsEmpty

Declaration
public abstract bool IsEmpty { get; }
Property Value
Type Description
bool

Keyspace

Returns the keyspace this query operates on.

Note that not all Statement implementations specify on which keyspace they operate on so this method can return null. If null, it will operate on the default keyspace set during initialization (if it was set).

The keyspace returned is used as a hint for token-aware routing.

Declaration
public override string Keyspace { get; }
Property Value
Type Description
string
Overrides
Remarks

Consider using a ISession connected to single keyspace using Connect(string).

QueryAbortTimeout

Declaration
protected int QueryAbortTimeout { get; }
Property Value
Type Description
int

QueryTrace

Declaration
public QueryTrace QueryTrace { get; }
Property Value
Type Description
QueryTrace

RoutingKey

The routing key (in binary raw form) to use for token aware routing of this query.

The routing key is optional in the sense that implementers are free to return null. The routing key is an hint used for token aware routing (see

TokenAwarePolicy), and if provided should correspond to the binary value for the query partition key. However, not providing a routing key never causes a query to fail and if the load balancing policy used is not token aware, then the routing key can be safely ignored.
Declaration
public override RoutingKey RoutingKey { get; }
Property Value
Type Description
RoutingKey
Overrides
