[jira] [Created] (TINKERPOP-2523) Allow registration of listeners for traversal iteration begin/end events

Clément de Groc created TINKERPOP-2523:
------------------------------------------

             Summary: Allow registration of listeners for traversal iteration begin/end events
                 Key: TINKERPOP-2523
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-2523
             Project: TinkerPop
          Issue Type: Improvement
          Components: server
    Affects Versions: 3.4.10
            Reporter: Clément de Groc


In order to improve observability/monitoring (e.g. distributed tracing, logging of traversals requests), it would be nice if users could register custom listeners for traversal iteration begin/end events.

Those begin/end events are actually already nicely exposed as protected methods in [TraversalOpProcessor|https://github.com/apache/tinkerpop/blob/master/gremlin-server/src/main/java/org/apache/tinkerpop/gremlin/server/op/traversal/TraversalOpProcessor.java#L262-L272]. Though, in 3.4.10, it is difficult to subclass TraversalOpProcessor to override those methods as the [OpLoader|https://github.com/apache/tinkerpop/blob/master/gremlin-server/src/main/java/org/apache/tinkerpop/gremlin/server/op/OpLoader.java#L47] ensures only one OpProcessor can be loaded with name "traversal".
