-----------------------------------------
Summary: JDBC URL completer uses outdated topology
Key: IGNITE-21989
URL: https://issues.apache.org/jira/browse/IGNITE-21989
Project: Ignite
Issue Type: Improvement
Components: cli
Reporter: Vadim Pakhnushev
Assignee: Vadim Pakhnushev
{{JdbcUrlRegistryImpl}} uses {{NodeNameRegistry}} in order to get all nodes
URLs. These registries are updated periodically and it so happens that the
order is {{JdbcUrlRegistry}} then {{NodeNameRegistry}} so {{JdbcUrlRegistry}}
always uses outdated topology information.
For example, after the first connect valid JDBC URL completion happens only
after second update which by default happens every 5 seconds.
When node leaves the cluster, this could lead to unwanted delays in updates
where {{JdbcUrlRegistry}} tries to connect to the already left node.
This was found when running the
{{ItIgnitePicocliCommandsTest#startStopNodeWhenCompleteNodeName}} on Windows,
where connect attempt takes a lot of time if the node is stopped.
