AllPostingsKey returns the label key that is used to store the postings list of all existing IDs.

EmptyPostings returns a postings list that's always empty.

ErrPostings returns new postings that immediately error.

ExpandPostings returns the postings expanded as a slice.

Intersect returns a new postings list over the intersection of the input postings.

Merge returns a new iterator over the union of the input iterators.

NewFileReader returns a new index reader against the given index file.

NewMemPostings returns a memPostings that's ready for reads and writes.

NewReader returns a new index reader on the given byte slice.

Note: shardedPostings can technically return more series than just those that correspond to the requested shard.

ReadOffsetTable reads an offset table and at the given position calls f for each found entry.

Without returns a new postings list that contains all elements from the full list that are not in the drop list.

Chunks per page.

Minimum number of chunks present to use page based lookup instead of linear scan which performs better at lower n-values.

MagicIndex 4 bytes at the head of an index file.

ShardLabel is a reserved label referencing a cortex shard.

ShardLabelFmt is the fmt of the ShardLabel key.

Meta holds information about a chunk of data.

Decoder provides decoding methods It currently does not contain decoding methods for all entry types but can be extended by them if there's demand.

ListPostings implements the Postings interface over a plain list.

MemPostings holds postings list for series ID per label pair.

Metadata is TSDB-level metadata.

PostingsStats contains cardinality based statistics for postings.

Range marks a byte range.

ShardAnnotation is a convenience struct which holds data from a parsed shard label Of MUST be a power of 2 to ensure sharding logic works correctly.

Stat holds values for a single cardinality statistic.

TOC represents index Table Of Content that states where each section of index starts.

Writer implements the IndexWriter interface for the standard serialization format.

ByteSlice abstracts a byte slice.

Postings provides iterative access over a postings list.
