Types

type CmdIDKey

type CmdIDKey string

CmdIDKey is a Raft command id.

type FilterArgs

type FilterArgs struct {
	Ctx   context.Context
	CmdID CmdIDKey
	Index int
	Sid   roachpb.StoreID
	Req   roachpb.Request
	Hdr   roachpb.Header
}

FilterArgs groups the arguments to a ReplicaCommandFilter.

func (*FilterArgs) InRaftCmd

func (f *FilterArgs) InRaftCmd() bool

InRaftCmd returns true if the filter is running in the context of a Raft command (it could be running outside of one, for example for a read).

type ReplicaCommandFilter

type ReplicaCommandFilter func(args FilterArgs) *roachpb.Error

ReplicaCommandFilter may be used in tests through the StorageTestingMocker 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. Note that in a multi-replica test this filter will be run once for each replica and must produce consistent results each time.
