Alex Auvolat	413ab0eaed	Small change to partition assignation algorithm ... This change helps ensure that nodes for each partition are spread over all datacenters, a property that wasn't ensured previously when going from a 2 DC deployment to a 3 DC deployment	2022-03-24 15:27:10 +01:00
Alex Auvolat	c94406f428	Improve how node roles are assigned in Garage ... - change the terminology: the network configuration becomes the role table, the configuration of a nodes becomes a node's role - the modification of the role table takes place in two steps: first, changes are staged in a CRDT data structure. Then, once the user is happy with the changes, they can commit them all at once (or revert them). - update documentation - fix tests - implement smarter partition assignation algorithm This patch breaks the format of the network configuration: when migrating, the cluster will be in a state where no roles are assigned. All roles must be re-assigned and commited at once. This migration should not pose an issue.	2021-11-16 16:05:53 +01:00
