We encode variable-length integers in little-endian order +** using seven bits * per byte as follows: +** +** KEY: +** A = 0xxxxxxx 7 bits of data and one flag bit +** B = 1xxxxxxx 7 bits of data and one flag bit +** +** 7 bits - A +** 14 bits - BA +** 21 bits - BBA +** and so on. +** +** This is identical to how sqlite encodes varints (see util.c). +** +** +**** Document lists **** +** A doclist (document list) holds a docid-sorted list of hits for a +** given term. Doclists hold docids, and can optionally associate +** token positions and offsets with docids. +** +** A DL_POSITIONS_OFFSETS doclist is stored like this: +** +** array { +** varint docid; +** array { (position list for column 0) +** varint position; (delta from previous position plus POS_BASE) +** varint startOffset; (delta from previous startOffset) +** varint endOffset; (delta from startOffset) +** } +** array { +** varint POS_COLUMN; (marks start of position list for new column) +** varint column; (index of new column) +** array { +** varint position; (delta from previous position plus POS_BASE) +** varint startOffset;(delta from previous startOffset) +** varint endOffset; (delta from startOffset) +** } +** } +** varint POS_END; (marks end of positions for this document. +** } +** +** Here, array { X } means zero or more occurrences of X, adjacent in +** memory. A "position" is an index of a token in the token stream +** generated by the tokenizer, while an "offset" is a byte offset, +** both based at 0. Note that POS_END and POS_COLUMN occur in the +** same logical place as the position element, and act as sentinals +** ending a position list array. +** +** A DL_POSITIONS doclist omits the startOffset and endOffset +** information. A DL_DOCIDS doclist omits both the position and +** offset information, becoming an array of varint-encoded docids. +** +** On-disk data is stored as type DL_DEFAULT, so we don't serialize +** the type. Due to how deletion is implemented in the segmentation +** system, on-disk doclists MUST store at least positions. +** +** +**** Segment leaf nodes **** +** Segment leaf nodes store terms and doclists, ordered by term. Leaf +** nodes are written using LeafWriter, and read using LeafReader (to +** iterate through a single leaf node's data) and LeavesReader (to +** iterate through a segment's entire leaf layer). Leaf nodes have +** the format: +** +** varint iHeight; (height from leaf level, always 0) +** varint nTerm; (length of first term) +** char pTerm[nTerm]; (content of first term) +** varint nDoclist; (length of term's associated doclist) +** char pDoclist[nDoclist]; (content of doclist) +** array { +** (further terms are delta-encoded) +** varint nPrefix; (length of prefix shared with previous term) +** varint nSuffix; (length of unshared suffix) +** char pTermSuffix[nSuffix];(unshared suffix of next term) +** varint nDoclist; (length of term's associated doclist) +** char pDoclist[nDoclist]; (content of doclist) +** } +** +** Here, array { X } means zero or more occurrences of X, adjacent in +** memory. +** +** Leaf nodes are broken into blocks which are stored contiguously in +** the %_segments table in sorted order. This means that when the end +** of a node is reached, the next term is in the node with the next +** greater node id. +** +** New data is spilled to a new leaf node when the current node +** exceeds LEAF_MAX bytes (default 2048). New data which itself is +** larger than STANDALONE_MIN (default 1024) is placed in a standalone +** node (a leaf node with a single term and doclist). The goal of +** these settings is to pack together groups of small doclists while +** making it efficient to directly access large doclists. The +** assumption is that large doclists represent terms which are more +** likely to be query targets. +** +** TODO(shess) It may be useful for blocking decisions to be more +** dynamic. For instance, it may make more sense to have a 2.5k leaf +** node rather than splitting into 2k and .5k nodes. My intuition is +** that this might extend through 2x or 4x the pagesize. +** +** +**** Segment interior nodes **** +** Segment interior nodes store blockids for subtree nodes and terms +** to describe what data is stored by the each subtree. Interior +** nodes are written using InteriorWriter, and read using +** InteriorReader. InteriorWriters are created as needed when +** SegmentWriter creates new leaf nodes, or when an interior node +** itself grows too big and must be split. The format of interior +** nodes: +** +** varint iHeight; (height from leaf level, always >0) +** varint iBlockid; (block id of node's leftmost subtree) +** optional { +** varint nTerm; (length of first term) +** char pTerm[nTerm]; (content of first term) +** array { +** (further terms are delta-encoded) +** varint nPrefix; (length of shared prefix with previous term) +** varint nSuffix; (length of unshared suffix) +** char pTermSuffix[nSuffix]; (unshared suffix of next term) +** } +** } +** +** Here, optional { X } means an optional element, while array { X } +** means zero or more occurrences of X, adjacent in memory. +** +** An interior node encodes n terms separating n+1 subtrees. The +** subtree blocks are contiguous, so only the first subtree's blockid +** is encoded. The subtree at iBlockid will contain all terms less +** than the first term encoded (or all terms if no term is encoded). +** Otherwise, for terms greater than or equal to pTerm[i] but less +** than pTerm[i+1], the subtree for that term will be rooted at +** iBlockid+i. Interior nodes only store enough term data to +** distinguish adjacent children (if the rightmost term of the left +** child is "something", and the leftmost term of the right child is +** "wicked", only "w" is stored). +** +** New data is spilled to a new interior node at the same height when +** the current node exceeds INTERIOR_MAX bytes (default 2048). +** INTERIOR_MIN_TERMS (default 7) keeps large terms from monopolizing +** interior nodes and making the tree too skinny. The interior nodes +** at a given height are naturally tracked by interior nodes at +** height+1, and so on. +** +** +**** Segment directory **** +** The segment directory in table %_segdir stores meta-information for +** merging and deleting segments, and also the root node of the +** segment's tree. +** +** The root node is the top node of the segment's tree after encoding +** the entire segment, restricted to ROOT_MAX bytes (default 1024). +** This could be either a leaf node or an interior node. If the top +** node requires more than ROOT_MAX bytes, it is flushed to %_segments +** and a new root interior node is generated (which should always fit +** within ROOT_MAX because it only needs space for 2 varints, the +** height and the blockid of the previous root). +** +** The meta-information in the segment directory is: +** level - segment level (see below) +** idx - index within level +** - (level,idx uniquely identify a segment) +** start_block - first leaf node +** leaves_end_block - last leaf node +** end_block - last block (including interior nodes) +** root - contents of root node +** +** If the root node is a leaf node, then start_block, +** leaves_end_block, and end_block are all 0. +** +** +**** Segment merging **** +** To amortize update costs, segments are groups into levels and +** merged in matches. Each increase in level represents exponentially +** more documents. +** +** New documents (actually, document updates) are tokenized and +** written individually (using LeafWriter) to a level 0 segment, with +** incrementing idx. When idx reaches MERGE_COUNT (default 16), all +** level 0 segments are merged into a single level 1 segment. Level 1 +** is populated like level 0, and eventually MERGE_COUNT level 1 +** segments are merged to a single level 2 segment (representing +** MERGE_COUNT^2 updates), and so on. +** +** A segment merge traverses all segments at a given level in +** parallel, performing a straightforward sorted merge. Since segment +** leaf nodes are written in to the %_segments table in order, this +** merge traverses the underlying sqlite disk structures efficiently. +** After the merge, all segment blocks from the merged level are +** deleted. +** +** MERGE_COUNT controls how often we merge segments. 16 seems to be +** somewhat of a sweet spot for insertion performance. 32 and 64 show +** very similar performance numbers to 16 on insertion, though they're +** a tiny bit slower (perhaps due to more overhead in merge-time +** sorting). 8 is about 20% slower than 16, 4 about 50% slower than +** 16, 2 about 66% slower than 16. +** +** At query time, high MERGE_COUNT increases the number of segments +** which need to be scanned and merged. For instance, with 100k docs +** inserted: +** +** MERGE_COUNT segments +** 16 25 +** 8 12 +** 4 10 +** 2 6 +** +** This appears to have only a moderate impact on queries for very +** frequent terms (which are somewhat dominated by segment merge +** costs), and infrequent and non-existent terms still seem to be fast +** even with many segments. +** +** TODO(shess) That said, it would be nice to have a better query-side +** argument for MERGE_COUNT of 16. Also, it's possible/likely that +** optimizations to things like doclist merging will swing the sweet +** spot around. +** +** +** +**** Handling of deletions and updates **** +** Since we're using a segmented structure, with no docid-oriented +** index into the term index, we clearly cannot simply update the term +** index when a document is deleted or updated. For deletions, we +** write an empty doclist (varint(docid) varint(POS_END)), for updates +** we simply write the new doclist. Segment merges overwrite older +** data for a particular docid with newer data, so deletes or updates +** will eventually overtake the earlier data and knock it out. The +** query logic likewise merges doclists so that newer data knocks out +** older data. +** +** TODO(shess) Provide a VACUUM type operation to clear out all +** deletions and duplications.

A +dynamically typed language can be seen as a statically-typed language +with a very permissive type system under which any syntactically +correct program is well-typed; as long as its dynamic semantics +ensures that no such program ever "goes wrong" in an appropriate +sense, it satisfies the definition above and can be called type-safe. +</blockquote> + + + + +}
