[Questions] Clustering

[ltagliamonte-dd]

Hello @sinkingpoint, i'd like to ask few questions about clustering:

• is this feature using any membership algorithm (like serf for example) so that if a node of the cluster is down the metric gets re-assigned to another node?
• is the metric proxy best effort? If a node is down or temp unavailable the data point just discarded?
• can the cluster be scaled in-out? is the data re-organized when this happens?

From what i'm reading the current clustering feature is just best-effort and depending on the requirements not production ready?

No

Yes

can the cluster be scaled in-out? is the data re-organized when this happens?

Yes, with some caveats. Currently we use a hash ring to decide which metrics push goes where. This means that if a node leaves and comes back then metrics will be assigned correct, and scaling out will in theory balance properly

Correct
