Interface GraphExecutionInfo

Deprecated.

This interface is not used by any driver component anymore; the driver now exposes instances of ExecutionInfo for all Graph queries.

@Deprecated
public interface GraphExecutionInfo

Information about the execution of a graph statement.

Method Summary

Modifier and Type	Method and Description
Node	getCoordinator() Deprecated. The node that was used as a coordinator to successfully complete the query.
List<Map.Entry<Node,Throwable>>	getErrors() Deprecated. The errors encountered on previous coordinators, if any.
Map<String,ByteBuffer>	getIncomingPayload() Deprecated. The custom payload sent back by the server with the response, if any (otherwise the map will be empty).
int	getSpeculativeExecutionCount() Deprecated. The number of speculative executions that were started for this query.
GraphStatement<?>	getStatement() Deprecated. The statement that was executed.
int	getSuccessfulExecutionIndex() Deprecated. The index of the execution that completed this query.
List<String>	getWarnings() Deprecated. The server-side warnings for this query, if any (otherwise the list will be empty).

Method Detail

getStatement

GraphStatement<?> getStatement()

Deprecated.

The statement that was executed.

getCoordinator

Node getCoordinator()

Deprecated.

The node that was used as a coordinator to successfully complete the query.

getSpeculativeExecutionCount

int getSpeculativeExecutionCount()

Deprecated.

The number of speculative executions that were started for this query.

This does not include the initial, normal execution of the query. Therefore, if speculative executions are disabled, this will always be 0. If they are enabled and one speculative execution was triggered in addition to the initial execution, this will be 1, etc.

SpeculativeExecutionPolicy

getSuccessfulExecutionIndex

int getSuccessfulExecutionIndex()

Deprecated.

The index of the execution that completed this query.

0 represents the initial, normal execution of the query, 1 the first speculative execution, etc.

getErrors

List<Map.Entry<Node,Throwable>> getErrors()

Deprecated.

The errors encountered on previous coordinators, if any.

The list is in chronological order, based on the time that the driver processed the error responses. If speculative executions are enabled, they run concurrently so their errors will be interleaved. A node can appear multiple times (if the retry policy decided to retry on the same node).

getWarnings

List<String> getWarnings()

Deprecated.

The server-side warnings for this query, if any (otherwise the list will be empty).

This feature is only available with DefaultProtocolVersion.V4 or above; with lower versions, this list will always be empty.

getIncomingPayload

Map<String,ByteBuffer> getIncomingPayload()

Deprecated.

The custom payload sent back by the server with the response, if any (otherwise the map will be empty).

This method returns a read-only view of the original map, but its values remain inherently mutable. If multiple clients will read these values, care should be taken not to corrupt the data (in particular, preserve the indices by calling ByteBuffer.duplicate()).

This feature is only available with DefaultProtocolVersion.V4 or above; with lower versions, this map will always be empty.
