public static final class Client.ClusteredClient extends Client
Client implementation that does not operate in a session. Requests are sent to multiple servers
given a LoadBalancingStrategy. Transactions are automatically committed
(or rolled-back on error) after each request.Client.AliasClusteredClient, Client.ClusteredClient, Client.SessionedClient, Client.SessionSettings, Client.Settings| Modifier and Type | Field and Description |

Client |
alias(Map<String,String> aliases)
Creates a
Client that supplies the specified set of aliases, thus allowing the user to re-name
one or more globally defined Graph or TraversalSource server bindings for the context of
the created Client. |
Client |
alias(String graphOrTraversalSource)
Create a new
Client that aliases the specified Graph or TraversalSource name on the
server to a variable called "g" for the context of the requests made through that Client. |
protected org.apache.tinkerpop.gremlin.driver.Connection |
chooseConnection(RequestMessage msg)
Uses a
LoadBalancingStrategy to choose the best Host and then selects the best connection
from that host's connection pool. |
CompletableFuture<Void> |
closeAsync()
Closes all the connection pools on all hosts.
|
protected void |
initializeImplementation()
Initializes the connection pools on all hosts.

boolean |
isClosing() |
ResultSet |
submit(String gremlin,
String graphOrTraversalSource)
Submits a Gremlin script to the server and returns a
ResultSet once the write of the request is
complete. |
ResultSet |
submit(String gremlin,
String graphOrTraversalSource,
Map<String,Object> parameters)
Submits a Gremlin script and bound parameters to the server and returns a
ResultSet once the write of
the request is complete. |

ResultSet once the write of
the request is complete. If a script is to be executed repeatedly with slightly different arguments, prefer
this method to concatenating a Gremlin script from dynamically produced strings and sending it to
Client.submit(String).
