Review Comment:
There are server side metrics and/or logs that can be asserted against when
a session is created/destroyed. This is a test that should be added but needs
to wait on https://github.com/apache/tinkerpop/pull/3258
> Add mechanism to close session without closing connection on server
> -------------------------------------------------------------------
>
> Key: TINKERPOP-3217
> URL: https://issues.apache.org/jira/browse/TINKERPOP-3217
> Project: TinkerPop
> Issue Type: Improvement
> Components: server
> Affects Versions: 3.8.0, 3.7.5
> Reporter: Ken Hu
> Priority: Major
>
> Currently, the Gremlin Server expects a closing of the underlying connection
> to signal that the corresponding Session tied to the connection should be
> closed. This is part of the [SessionOpProcessor
> reference|https://tinkerpop.apache.org/docs/current/dev/provider/#_session_opprocessor].
> An option should be added to the server so that alternative would be that
> the Session closes automatically if a successful commit or rollback occurs.
> This would only affect the Bytecode portion of the SessionOpProcessor that
> makes the Session act like a Transaction. This would allow connection re-use
> of connections for sessions and enable better performance for use cases that
> require large number of transactions to occur.
> This needs to be an option to prevent breaking changes in the server in 3.7.x
> and 3.8.x. In 4.x and later, this should probably be the default option.
