Summary: Provide method for provider plugins to get notified on
script/query processing
Key: TINKERPOP-2806
URL: https://issues.apache.org/jira/browse/TINKERPOP-2806
Project: TinkerPop
Issue Type: Bug
Components: server
Affects Versions: 3.6.1
Reporter: Tom Kolanko
Fix For: 3.6.2
What happens in the gremlin-server is more or less a black box for provider
plugins. This ticket proposes a change to the GraphManager interface to allow
providers to opt into receiving notifications for GremlinExecutor lifecycles.
The following items could be added to the GraphManager interface:
default void beforeQueryStart(String requestID, Map<String, Object> args) {}
default void onQueryError(String requestID, String error) {}
default void onQuerySuccess(String requestID) {}
default void onQueryTimeout(String requestID, long evaluationTimeout) {}
In AbstractEvalOpProcessor where the GremlinExector.LifeCycle is created the
graphManager can be accessed through the Context and those methods called at
each stage of the lifecycle.
In TraversalOpProcessor the graphManager can also be accessed through context.
Similar methods exist to the GremlinExecutor.LifeCycle, those can call the
graphManager methods as needed.
