per-request timeout for scripts is
with bytecode may try `g.with(EVALUATION_TIMEOUT, 500)` within a script.
Scripts with multiple traversals and multiple
timeouts will be interpreted as a sum of all timeouts identified in the script
for that request.

+==== Processing results as they are returned from the Gremlin server
+
+
+The Gremlin JavaScript driver maintains a WebSocket connection to the Gremlin
server and receives messages according to the `batchSize` parameter on the per
request settings or the `resultIterationBatchSize` value configured for the
Gremlin server. When submitting scripts the default behavior is to wait for the
entire result set to be returned from a query before allowing any processing on
the result set.
+
+The following examples assume that you have 100 vertices in your graph.
+
+[source,javascript]
+----
+const result = await client.submit("g.V()");
+console.log(result.toArray()); // 100 - all the vertices in your graph
+----
+
+When working with larger result sets it may be beneficial for memory
management to process each chunk of data as it is returned from the gremlin
server. The Gremlin JavaScript driver can accept an optional callback to run on
each chunk of data returned.
+
+[source,javascript]
+----
+
+await client.submit("g.V()", {}, { batchSize: 25 }, (data) => {
Review comment:
I think an async iterator is harder to implement in this case given that
the tinkerpop protocol doesn't allow to fetch the next page (it will continue
to serve the next "partial content").
I think an event emitter (emitter of result items) or a stream fit better in
this case.
