	// remove itself from the CommandQueue without executing.
	CommandQueueCancellation
	// CommandQueueBeginExecuting represents the state of a batchCmdSet when it
	// has finished waiting for all prereqs to finish execution and is now free
	// to execute itself.

type RaftCommand 

type RaftCommand struct {
	// proposer_replica is the replica which proposed this command, to be
	// used for lease validation.
	ProposerReplica cockroach_roachpb.ReplicaDescriptor `protobuf:"bytes,2,opt,name=proposer_replica,json=proposerReplica" json:"proposer_replica"`
	// proposer_lease is provided to verify at raft command apply-time that
	// the lease under which the command was proposed remains in effect.
	//
	// To see why lease verification downstream of Raft is required, consider the
	// following example:
	// - replica 1 receives a client request for a write
	// - replica 1 checks the lease; the write is permitted
	// - replica 1 proposes the command
	// - time passes, replica 2 commits a new lease
	// - the command applies on replica 1
	// - replica 2 serves anomalous reads which don't see the write
	// - the command applies on replica 2
	ProposerLease cockroach_roachpb1.Lease `protobuf:"bytes,5,opt,name=proposer_lease,json=proposerLease" json:"proposer_lease"`
	// When the command is applied, its result is an error if the lease log
	// counter has already reached (or exceeded) max_lease_index.
	//
	// The lease index is a reorder protection mechanism - we don't want Raft
	// commands (proposed by a single node, the one with proposer_lease) executing
	// in a different order than the one in which the corresponding KV requests
	// were evaluated and the commands were proposed. This is important because
	// the CommandQueue does not fully serialize commands - mostly when it comes
	// to updates to the internal state of the range (this should be re-evaluated
	// once proposer-evaluated KV is completed - see #10413).
	// Similar to the Raft applied index, it is strictly increasing, but may have
	// gaps. A command will only apply successfully if its max_lease_index has not
	// been surpassed by the Range's applied lease index (in which case the
	// command may need to be retried, that is, regenerated with a higher
	// max_lease_index). When the command applies, the new lease index will
	// increase to max_lease_index (so a potential later replay will fail).
	//
	// This mechanism was introduced as a simpler alternative to using the Raft
	// applied index, which is fraught with complexity due to the need to predict
	// exactly the log position at which a command will apply, even when the Raft
	// leader is not colocated with the lease holder (which usually proposes all
	// commands).
	//
	// Pinning the lease-index to the assigned slot (as opposed to allowing gaps
	// as we do now) is an interesting venue to explore from the standpoint of
	// parallelization: One could hope to enforce command ordering in that way
	// (without recourse to a higher-level locking primitive such as the command
	// queue). This is a hard problem: First of all, managing the pending
	// commands gets more involved; a command must not be removed if others have
	// been added after it, and on removal, the assignment counters must be
	// updated accordingly. Managing retry of proposals becomes trickier as
	// well as that uproots whatever ordering was originally envisioned.
	MaxLeaseIndex uint64 `protobuf:"varint,4,opt,name=max_lease_index,json=maxLeaseIndex" json:"max_lease_index"`
	// testing_batch_request is the KV request that generated this Raft command.
	//
	// TODO(bdarnell): This used to be a pre-proposer-evaluated-kv field; we're
	// now exclusively proposer-evaluated, but it is still needed by certain tests
	// that use TestingEvalFilter. See #10493.
	TestingBatchRequest  *cockroach_roachpb3.BatchRequest `protobuf:"bytes,3,opt,name=testing_batch_request,json=testingBatchRequest" json:"testing_batch_request,omitempty"`
	ReplicatedEvalResult ReplicatedEvalResult             `protobuf:"bytes,13,opt,name=replicated_eval_result,json=replicatedEvalResult" json:"replicated_eval_result"`
	WriteBatch           *WriteBatch                      `protobuf:"bytes,14,opt,name=write_batch,json=writeBatch" json:"write_batch,omitempty"`
}

RaftCommand is the message written to the raft log. It contains some metadata about the proposal itself, then either a BatchRequest (legacy mode) or a ReplicatedEvalResult + WriteBatch (proposer-evaluated KV mode).

type ReplicaApplyFilter 

type ReplicaApplyFilter func(args ApplyFilterArgs) *roachpb.Error

A ReplicaApplyFilter can be used in testing to influence the error returned from proposals after they apply.

type ReplicaCommandFilter 

type ReplicaCommandFilter func(args FilterArgs) *roachpb.Error

ReplicaCommandFilter may be used in tests through the StoreTestingKnobs to intercept the handling of commands and artificially generate errors. Return nil to continue with regular processing or non-nil to terminate processing with the returned error.

type ReplicaResponseFilter 

type ReplicaResponseFilter func(roachpb.BatchRequest, *roachpb.BatchResponse) *roachpb.Error

ReplicaResponseFilter is used in unittests to modify the outbound response returned to a waiting client after a replica command has been processed. This filter is invoked only by the command proposer.

type ReplicaState 

type ReplicaState struct {
	// The highest (and last) index applied to the state machine.
	RaftAppliedIndex uint64 `protobuf:"varint,1,opt,name=raft_applied_index,json=raftAppliedIndex,proto3" json:"raft_applied_index,omitempty"`

	LeaseAppliedIndex uint64 `protobuf:"varint,2,opt,name=lease_applied_index,json=leaseAppliedIndex,proto3" json:"lease_applied_index,omitempty"`
	// The Range descriptor.
	// The pointer may change, but the referenced RangeDescriptor struct itself
	// must be treated as immutable; it is leaked out of the lock.
	//
	// Changes of the descriptor should always go through one of the
	// (*Replica).setDesc* methods.
	Desc *cockroach_roachpb.RangeDescriptor `protobuf:"bytes,3,opt,name=desc" json:"desc,omitempty"`
	// The latest range lease.
	//
	// Note that this message is both sent over the network and used to model
	// replica state in memory. In memory (storage.Replica.mu.state), the lease
	// is never nil (and never zero-valued), but it may be nil when sent over
	// the network as part of ReplicatedEvalResult.
	//
	// TODO(tamird): consider changing the type of storage.Replica.mu.state to
	// avoid the nullability there.
	Lease *cockroach_roachpb1.Lease `protobuf:"bytes,4,opt,name=lease" json:"lease,omitempty"`
	// The truncation state of the Raft log.
	TruncatedState *cockroach_roachpb4.RaftTruncatedState `protobuf:"bytes,5,opt,name=truncated_state,json=truncatedState" json:"truncated_state,omitempty"`
	// gcThreshold is the GC threshold of the Range, typically updated when keys
	// are garbage collected. Reads and writes at timestamps <= this time will
	// not be served.
	//
	// TODO(tschottdorf): should be nullable to keep ReplicaState small as we are
	// sending it over the wire. Since we only ever increase gc_threshold, that's
	// the only upshot - fields which can return to the zero value must
	// special-case that value simply because otherwise there's no way of
	// distinguishing "no update" to and updating to the zero value.
	GCThreshold cockroach_util_hlc.Timestamp                `protobuf:"bytes,6,opt,name=gc_threshold,json=gcThreshold" json:"gc_threshold"`

	// txn_span_gc_threshold is the (maximum) timestamp below which transaction
	// records may have been garbage collected (as measured by txn.LastActive()).
	// Transaction at lower timestamps must not be allowed to write their initial
	// transaction entry.
	//
	// TODO(tschottdorf): should be nullable; see gc_threshold.
	TxnSpanGCThreshold cockroach_util_hlc.Timestamp `protobuf:"bytes,9,opt,name=txn_span_gc_threshold,json=txnSpanGcThreshold" json:"txn_span_gc_threshold"`
}

ReplicaState is the part of the Range Raft state machine which is cached in memory and which is manipulated exclusively through consensus.

The struct is also used to transfer state to Replicas in the context of proposer-evaluated Raft, in which case it does not represent a complete state but instead an update to be applied to an existing state, with each field specified in the update overwriting its counterpart on the receiving ReplicaState.

For the ReplicaState persisted on the Replica, all optional fields are populated (i.e. no nil pointers or enums with the default value).

ReplicatedEvalResult is the structured information which together with a RocksDB WriteBatch constitutes the proposal payload in proposer-evaluated KV. For the majority of proposals, we expect ReplicatedEvalResult to be trivial; only changes to the metadata state (splits, merges, rebalances, leases, log truncation, ...) of the Replica or certain special commands must sideline information here based on which all Replicas must take action.

	CRC32 uint32 `protobuf:"varint,2,opt,name=crc32" json:"crc32"`
}

AddSSTable is a side effect that must execute before the Raft application is committed. It must be idempotent to account for an ill-timed crash after applying the side effect, but before committing the batch.

TODO(tschottdorf): additionally, after the crash, the node must not serve traffic until the persisted committed log has fully applied. Otherwise, we risk exposing data created through such a side effect whose corresponding Raft command hasn't committed yet. This isn't so much an issue with AddSSTable since these Ranges are not user-visible, but it is a general concern assuming other such side effects are added.

Split is emitted when a Replica commits a split trigger. It signals that the Replica has prepared the on-disk state for both the left and right hand sides of the split, and that the left hand side Replica should be updated as well as the right hand side created.

WriteBatch is the serialized representation of a RocksDB write batch. A wrapper message is used so that the absence of the field can be distinguished from a zero-length batch, and so structs containing pointers to it can be compared with the == operator (we rely on this in storage.EvalResult)
