Work around a keep-alive bug in clients earlier than 3.3.4

Only for client versions 3.3.3 and below:

There is a bug in earlier version of the Gremlin client causing a new KeepAlive request to be sent to the server with every query instead of once per websocket connection. This consumes precious server resources as the server processes unnecessary keep-alive requests. For more information, see TINKERPOP-2030.

You can avoid this problem by upgrading to Gremlin Java Client version 3.3.4 or above.

A workaround is to disable the keep-alive from the client by setting its interval to 0:

Cluster.Builder readerBuilder = Cluster.build()
          .port(8182)
          ...
          .keepAliveInterval(0)
