Summary: JDBC: update connection setup logic. Key: IGNITE-11258 URL: https://issues.apache.org/jira/browse/IGNITE-11258 Project: Ignite Issue Type: Task Components: sql Reporter: Alexander Lapin # On thin client startup it connects to *all* *nodes* provided by user by client configuration. # Upon handshake server returns its UUID to client. # By the end of the startup procedure, client have open connections to all available server nodes and the following mapping (*nodeMap*): [UUID => Connection]. Connection to all nodes helps to identify available nodes, but can lead to significant delay, when thin client is used on a large cluster with a long IP list provided by user. To lower this delay, asynchronous establishment of connections can be used.
