39640: storage: unify replica addition and removal paths r=nvanbenschoten a=tbg This continues the reworking of the various replication change APIs with the goal of allowing a) testing of general atomic replication changes b) issuing replica swaps from the replicate queue (in 19.2). For previous steps, see: #39485 #39611 This change is not a pure plumbing PR. Instead, it unifies `(*Replica).addReplica` and `(*Replica).removeReplica` into a method that can do both, `(*Replica).addAndRemoveReplicas`. Given a slice of ReplicationChanges, this method first adds learner replicas corresponding to the desired new voters. After having sent snapshots to all of them, the method issues a configuration change that atomically - upgrades all learners to voters - removes any undesired replicas. Note that no atomic membership changes are *actually* carried out yet. This is because the callers of `addAndRemoveReplicas` pass in only a single change (i.e. an addition or removal), which the method also verifies. Three pieces are missing after this PR: First, we need to be able to instruct raft to carry out atomic configuration changes: https://github.com/cockroachdb/cockroach/blob/2e8db6ca53c59d3d281e64939f79d937195403d4/pkg/storage/replica_proposal_buf.go#L448-L451 which in particular requires being able to store the ConfState corresponding to a joint configuration in the unreplicated local state (under a new key). Second, we must pass the slice of changes handed to `AdminChangeReplicas` through to `addAndRemoveReplicas` without unrolling it first, see: https://github.com/cockroachdb/cockroach/blob/3b316bac6ef342590ddc68d2989714d6e126371a/pkg/storage/replica_command.go#L870-L891 and https://github.com/cockroachdb/cockroach/blob/3b316bac6ef342590ddc68d2989714d6e126371a/pkg/storage/replica.go#L1314-L1325 Third, we must to teach the replicate queue to issue the "atomic swaps"; this is the reason we're introducing atomic membership changes in the first place. Release note: None 39656: kv: init heartbeat txn log tag later r=nvanbenschoten a=tbg At init() time, the txn proto has not been populated yet. Found while investigating #39652. This change strikes me as clunky, but I don't have the bandwidth to dig deeper right now.
