Constants ¶

(000001, 000002, 000003). SegmentsFormat1Based6Digits = "1b6d" )
const (

Variables ¶
var ( ErrIndexNotFound = errors.New("bucket index not found") ErrIndexCorrupted = errors.New("bucket index corrupted") )
var ( ErrBlockMetaNotFound = block.ErrorSyncMetaNotFound ErrBlockMetaCorrupted = block.ErrorSyncMetaCorrupted ErrBlockDeletionMarkNotFound = errors.New("block deletion mark not found") ErrBlockDeletionMarkCorrupted = errors.New("block deletion mark corrupted") )
Functions ¶
func BlockDeletionMarkFilepath ¶
BlockDeletionMarkFilepath returns the path, relative to the tenant's bucket location, of a block deletion mark in the bucket markers location.
func BucketWithGlobalMarkers ¶
BucketWithGlobalMarkers wraps the input bucket into a bucket which also keeps track of markers in the global markers location.
Types ¶
type Block ¶
type Block struct {
// Block ID.
ID ulid.ULID `json:"block_id"`
// MinTime and MaxTime specify the time range all samples in the block are in (millis precision).
MinTime int64 `json:"min_time"`
MaxTime int64 `json:"max_time"`
// SegmentsFormat and SegmentsNum stores the format and number of chunks segments
// in the block, if they match a known pattern. We don't store the full segments
// files list in order to keep the index small. SegmentsFormat is empty if segments
// are unknown or don't match a known format.
SegmentsFormat string `json:"segments_format,omitempty"`
SegmentsNum int `json:"segments_num,omitempty"`
// UploadedAt is a unix timestamp (seconds precision) of when the block has been completed to be uploaded
// to the storage.
UploadedAt int64 `json:"uploaded_at"`
}
Block holds the information about a block in the index.
func BlockFromThanosMeta ¶
func (*Block) GetUploadedAt ¶
type BlockDeletionMark ¶
type BlockDeletionMark struct {
// Block ID.
ID ulid.ULID `json:"block_id"`
// DeletionTime is a unix timestamp (seconds precision) of when the block was marked to be deleted.
DeletionTime int64 `json:"deletion_time"`
}
BlockDeletionMark holds the information about a block's deletion mark in the index.
func BlockDeletionMarkFromThanosMarker ¶
func BlockDeletionMarkFromThanosMarker(mark *metadata.DeletionMark) *BlockDeletionMark
type Blocks ¶
type Blocks []*Block
Blocks holds a set of blocks in the index. No ordering guaranteed.
type Index ¶
type Index struct {
// Version of the index format.
Version int `json:"version"`
// List of complete blocks (partial blocks are excluded from the index).
Blocks []*Block `json:"blocks"`
// List of block deletion marks.
BlockDeletionMarks []*BlockDeletionMark `json:"block_deletion_marks"`
// UpdatedAt is a unix timestamp (seconds precision) of when the index has been updated
// (written in the storage) the last time.
UpdatedAt int64 `json:"updated_at"`
}
Index contains all known blocks and markers of a tenant.
type Writer ¶
type Writer struct {
// contains filtered or unexported fields
}
Writer is responsible to generate and write a bucket index.
func (*Writer) GenerateIndex ¶
GenerateIndex generates the bucket index and returns it, without storing it to the storage. If the old index is not passed in input, then the bucket index will be generated from scratch.
