Labels: ignite-3 (was: )
> Thin 3.0: Cluster Discovery for Java thin client
> ------------------------------------------------
>
> Key: IGNITE-16609
> URL: https://issues.apache.org/jira/browse/IGNITE-16609
> Project: Ignite
> Issue Type: New Feature
> Components: thin client
> Affects Versions: 3.0.0-alpha4
> Reporter: Igor Sapego
> Priority: Major
> Labels: ignite-3
> Fix For: 3.0.0-alpha5
>
>
> We should design and implement a mechanism for thin clients that will provide
> them with ability to discover nodes in cluster.
> My thoughts on the matter:
> If we implement this approach (which should be a default I belive) then
> initial addresses provided to thin client by a user should only be used to
> establish the first connection to a node of the cluster. After that, thin
> client should request full list of active nodes of the cluster and use them
> instead of the initial list to establish new connections.
> The problems that should be considered during desing and implementation steps:
> - How should clients be notified about changes in cluster (should clients
> send requests for that or should server issue notifications);
> - How should clients handle a situation when they can not reach cluster nodes
> by addresses provided by server.
> - How should clients behave on connection to nodes from different clusters.
> - How should clients handle different states of the cluster lifecycle.
> These problems should be probably addressed in separate tickets. In this
> case, those ticket should be created and linked to the current ticket.
