¶A TraversalBatch is used to execute multiple graph traversals in a single transaction. If any traversal in the batch fails, the entire batch will fail to apply.
If a TraversalBatch is bounded to a DSE session, it can be executed using traversal_batch.execute().
session – (Optional) A DSE session
execution_profile – (Optional) The execution profile to use for the batch execution
Add a traversal to the batch.
traversal – A gremlin GraphTraversal
Adds a sequence of traversals to the batch.
traversals – A sequence of gremlin GraphTraversal
Execute the traversal batch if bounded to a DSE Session.
Return the traversal batch as GraphStatement.
graph_protocol – The graph protocol for the GraphSONWriter. Default is GraphProtocol.GRAPHSON_2_0.
Clear a traversal batch for reuse.
