Alex Auvolat	c1d1646c4d	Change the way new layout assignations are computed. ... The function now computes an optimal assignation (with respect to partition size) that minimizes the distance to the former assignation, using flow algorithms.

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
