org.apache.tinkerpop.gremlin.driver.Client.PinnedClient

All Implemented Interfaces:

RequestSubmitter, RequestSubmitterAsync

Enclosing class:

Client

public static class Client.PinnedClient
extends Client

A Client that pins all requests of a single transaction to one Host. Used internally by transactions; obtain one indirectly via Cluster.transact() or Cluster.transact(String) rather than directly.

This is a lightweight routing view that owns no connection pools. All transactions share a single Client.ClusteredClient (one per Cluster) and borrow a connection per request from the pinned host's pool, returning it once the response completes. Those pools are closed when the Cluster closes, never by this client.
