Types

type DMap

type DMap struct {
	Name   string
	Length int

	// Statistics about memory representation of the dmap.
	SlabInfo SlabInfo
}

dmap denotes a distributed map instance on the cluster.

type Partition

type Partition struct {
	Owner          discovery.Member
	PreviousOwners []discovery.Member
	Backups        []discovery.Member
	Length         int
	DMaps          map[string]DMap
}

Partition denotes a partition and its metadata in the cluster.

type Runtime

type Runtime struct {
	GOOS         string
	GOARCH       string
	Version      string
	NumCPU       int
	NumGoroutine int
	MemStats     runtime.MemStats
}

Runtime exposes memory stats and various metrics from Go runtime.

type SlabInfo

type SlabInfo struct {
	// Total allocated space by the append-only log files.
	Allocated int

	// Total inuse memory space in the append-only log files.
	Inuse int

	// Total garbage(deleted key/value pairs) space in the append-only log files.
	Garbage int
}

SlabInfo denotes memory usage of the storage engine(a hash indexed append only log file).

type Stats

type Stats struct {
	Cmdline        []string
	ReleaseVersion string
	Runtime        Runtime
	Partitions     map[uint64]Partition
	Backups        map[uint64]Partition
}

Stats includes some metadata information about the cluster. The nodes add everything it knows about the cluster.
