Awesome to see progress on this! I had some trouble getting it to work
though. Here's what I id:
build it
```
git checkout TINKERPOP-575 #currently e01a71b
mvn clean install -DskipTests
```
start gremlin-server
```
unzip
$TP_SRC/gremlin-server/target/apache-gremlin-server-3.2.0-SNAPSHOT-distribution.zip
cd apache-gremlin-server-3.2.0-SNAPSHOT
bin/gremlin-server.sh conf/gremlin-server-modern.yaml
```
connect and run traversal
```
cd gremlin-console/target/apache-gremlin-console-3.2.0-SNAPSHOT-standalone
bin/gremlin.sh

==>graphtraversalsource[remotegraph[DriverServerConnection-localhost/127.0.0.1:8182

gremlin> g.V().valueMap(true)
```
No output :(
PS1: works fine for local TinkerGraph instance
PS2: Wireshark tells me that there is some communication between the REPL
and gremlin-server (three TCP packets).

> Key: TINKERPOP-575
> URL: https://issues.apache.org/jira/browse/TINKERPOP-575
> Project: TinkerPop
> Issue Type: Improvement
> Components: driver, process, server
> Affects Versions: 3.0.2-incubating
> Reporter: Bryn Cooke
> Assignee: stephen mallette
> Fix For: 3.2.0-incubating
>
>
> Consider implementing a graph that allows remote execution of portions of a
> gremlin query and locally executes steps that have lambda expressions.
> Graph r = new RemoteGraph("192.168.0.10") //Gremlin server
> r.V().has("age", 35).out().in().sideEffect(v->{do something});
> gets optimised to
> r.remoteStep("g.V().has("age", 35).out().in()").sideEffect(v->{do something});
> The remote step would be transmitted to the server for execution and the
> results pulled back allow the side effect to take place locally.
> All remote step optimisation is done via traversal strategy.
> Things to think about are:
> Transactions have to span multiple requests to the server.
> Strategies only work on the server side.
