Expand description

Section kinds (discriminants are burned; do not renumber).

Variants§

§

Nodes = 1

Fixed 72-B node records sorted by url_key.

§

Segs = 2

Fixed 24-B segment records grouped per node in document order.

§

EdgeIndex = 3

CSR offsets: (node_count + 1) × u32 into Edges.

§

Edges = 4

Fixed 8-B edge records, per-node runs sorted by destination id.

§

Labels = 5

Length-prefixed UTF-8 label heap.

§

Lexicon = 6

Fixed 24-B token records sorted by token_hash.

§

Postings = 7

LEB128 delta-encoded ascending node-id postings.

§

Ranks = 8

Fixed 2-B per-node rank percentiles (parallel to Nodes).

§

InEdgeIndex = 9

CSR offsets: (node_count + 1) × u32 into InEdges.

§

InEdges = 10

Fixed 8-B inbound records (source id, type, flags, weight), per-node runs sorted by source id: the reverse of Edges.

§

AttrIndex = 11

CSR offsets: (node_count + 1) × u32 into Attrs.

§

Attrs = 12

Fixed 12-B attribute records, per-node runs sorted by key.

§

Blobs = 13

UTF-8 attribute values, addressed by (offset, length).

§

LexOrder = 14

token_count × u32 lexicon indices in token string order: prefix lookups are a binary search.

§

Trigrams = 15

Fixed 12-B trigram records sorted by trigram: substring lookups intersect the postings of a term’s trigrams.

§

TriPostings = 16

Ascending u32 lexicon indices per trigram.
