pub fn upgrade(
snapshot: Vec<StateUpdateKind>,
) -> Vec<MigrationAction<StateUpdateKind, StateUpdateKind>>Expand description
Adds the arrangement_compression flag to managed clusters and cluster
replicas, backfilling it as false. The flag also appears on a managed
cluster’s in-flight reconfiguration target, backfilled the same way.
Managed Cluster and ClusterReplica records gained a new field, so their
stored JSON is no longer readable as the v90 type. Every such record is
rewritten. Unmanaged clusters and all other records are unchanged and pass
through untouched.
