func (p *Partition) EndTime() time.Time

func (*Partition) HasIndexShard ¶ added in v1.13.3

func (p *Partition) HasIndexShard(tenant string, shard uint32) bool

func (*Partition) HasTenant ¶

func (p *Partition) HasTenant(t string) bool

func (*Partition) Overlaps ¶

func (p *Partition) Overlaps(start, end time.Time) bool

func (*Partition) StartTime ¶

func (p *Partition) StartTime() time.Time

type PartitionKey ¶

type PartitionKey struct {
	Timestamp time.Time
	Duration  time.Duration
}

func NewPartitionKey ¶

func NewPartitionKey(timestamp time.Time, duration time.Duration) PartitionKey

func (PartitionKey) Bytes ¶

func (k PartitionKey) Bytes() []byte

func (*PartitionKey) EndTime ¶ added in v1.13.3

func (k *PartitionKey) EndTime() time.Time

func (PartitionKey) Equal ¶

func (k PartitionKey) Equal(x PartitionKey) bool

func (PartitionKey) MarshalBinary ¶

func (k PartitionKey) MarshalBinary() ([]byte, error)

func (*PartitionKey) Overlaps ¶ added in v1.13.3

func (k *PartitionKey) Overlaps(start, end time.Time) bool

func (*PartitionKey) StartTime ¶ added in v1.13.3

func (k *PartitionKey) StartTime() time.Time

func (PartitionKey) String ¶

func (k PartitionKey) String() string

func (*PartitionKey) UnmarshalBinary ¶

func (k *PartitionKey) UnmarshalBinary(b []byte) error

type Shard ¶ added in v1.13.3

type Shard struct {
	Partition PartitionKey
	Tenant    string
	Shard     uint32
	*metadata.StringTable
	ShardIndex
}

func (*Shard) Blocks ¶ added in v1.13.3

func (s *Shard) Blocks(tx *bbolt.Tx) *store.CursorIterator

func (*Shard) Delete ¶ added in v1.13.3

func (s *Shard) Delete(tx *bbolt.Tx, blocks ...string) error

func (*Shard) Find ¶ added in v1.13.3

func (s *Shard) Find(tx *bbolt.Tx, blocks ...string) []store.KV

func (*Shard) Overlaps ¶ added in v1.13.3

func (s *Shard) Overlaps(start, end time.Time) bool

func (*Shard) ShallowCopy ¶ added in v1.13.3

func (s *Shard) ShallowCopy() *Shard

ShallowCopy creates a shallow copy: no deep copy of the string table. The copy can be accessed safely by multiple readers, and it represents a snapshot of the string table at the time of the copy.

Strings added after the copy is made won't be visible to the reader. The writer MUST invalidate the cache before access: copies in-use can still be used (strings is a header copy of append-only slice).

func (*Shard) Store ¶ added in v1.13.3

func (s *Shard) Store(tx *bbolt.Tx, md *metastorev1.BlockMeta) error

type ShardIndex ¶ added in v1.13.3

type ShardIndex struct {
	MinTime int64
	MaxTime int64
}

func (*ShardIndex) MarshalBinary ¶ added in v1.13.3

func (i *ShardIndex) MarshalBinary() []byte

func (*ShardIndex) UnmarshalBinary ¶ added in v1.13.3

func (i *ShardIndex) UnmarshalBinary(data []byte) error
