-# Yjs Internals
-
-This document roughly explains how Yjs works internally. There is a complete
-walkthrough of the Yjs codebase available as a recording:
-https://youtu.be/0l5XgnQ6rB4
-
-The Yjs CRDT algorithm is described in the [YATA
-paper](https://www.researchgate.net/publication/310212186_Near_Real-Time_Peer-to-Peer_Shared_Editing_on_Extensible_Data_Types)
-from 2016. For an algorithmic view of how it works, the paper is a reasonable
-place to start. There are a handful of small improvements implemented in Yjs
-which aren't described in the paper. The most notable is that items have an
-`originRight` as well as an `origin` property, which improves performance when
-many concurrent inserts happen after the same character.
-
-At its heart, Yjs is a list CRDT. Everything is squeezed into a list in order to
-reuse the CRDT resolution algorithm:
-
-- Arrays are easy - they're lists of arbitrary items.
-- Text is a list of characters, optionally punctuated by formatting markers and
-  embeds for rich text support. Several characters can be wrapped in a single
-linked list `Item` (this is also known as the compound representation of
-CRDTs). More information about this in [this blog
-article](https://blog.kevinjahns.de/are-crdts-suitable-for-shared-editing/).
-- Maps are lists of entries. The last inserted entry for each key is used, and
-  all other duplicates for each key are flagged as deleted.
-
-Each client is assigned a unique *clientID* property on first insert. This is a
-random 53-bit integer (53 bits because that fits in the javascript safe integer
-range \[JavaScript uses IEEE 754 floats\]).
-
-## List items
-
-Each item in a Yjs list is made up of two objects:
-
-- An `Item` (*src/structs/Item.js*). This is used to relate the item to other
-  adjacent items.
-- An object in the `AbstractType` hierarchy (subclasses of
-  *src/types/AbstractType.js* - eg `YText`). This stores the actual content in
-the Yjs document.
-
-The item and type object pair have a 1-1 mapping. The item's `content` field
-references the AbstractType object and the AbstractType object's `_item` field
-references the item.
-
-Everything inserted in a Yjs document is given a unique ID, formed from a
-*ID(clientID, clock)* pair (also known as a [Lamport
-Timestamp](https://en.wikipedia.org/wiki/Lamport_timestamp)). The clock counts
-up from 0 with the first inserted character or item a client makes. This is
-similar to automerge's operation IDs, but note that the clock is only
-incremented by inserts. Deletes are handled in a very different way (see
-below).
-
-If a run of characters is inserted into a document (eg `"abc"`), the clock will
-be incremented for each character (eg 3 times here). But Yjs will only add a
-single `Item` into the list. This has no effect on the core CRDT algorithm, but
-the optimization dramatically decreases the number of javascript objects
-created during normal text editing. This optimization only applies if the
-characters share the same clientID, they're inserted in order, and all
-characters have either been deleted or all characters are not deleted. The item
-will be split if the run is interrupted for any reason (eg a character in the
-middle of the run is deleted).
-
-When an item is created, it stores a reference to the IDs of the preceding and
-succeeding item. These are stored in the item's `origin` and `originRight`
-fields, respectively. These are used when peers concurrently insert at the same
-location in a document. Though quite rare in practice, Yjs needs to make sure
-the list items always resolve to the same order on all peers. The actual logic
-is relatively simple - its only a couple dozen lines of code and it lives in
-the `Item#integrate()` method. The YATA paper has much more detail on this
-algorithm.
-
-### Item Storage
-
-The items themselves are stored in two data structures and a cache:
-
-- The items are stored in a tree of doubly-linked lists in *document order*.
-  Each item has `left` and `right` properties linking to its siblings in the
-document. Items also have a `parent` property to reference their parent in the
-document tree (null at the root). (And you can access an item's children, if
-any, through `item.content`).
-- All items are referenced in *insertion order* inside the struct store
-  (*src/utils/StructStore.js*). This references the list of items inserted by
-for each client, in chronological order. This is used to find an item in the
-tree with a given ID (using a binary search). It is also used to efficiently
-gather the operations a peer is missing during sync (more on this below).
-
-When a local insert happens, Yjs needs to map the insert position in the
-document (eg position 1000) to an ID. With just the linked list, this would
-require a slow O(n) linear scan of the list. But when editing a document, most
-inserts are either at the same position as the last insert, or nearby. To
-improve performance, Yjs stores a cache of the 80 most recently looked up
-insert positions in the document. This is consulted and updated when a position
-is looked up to improve performance in the average case. The cache is updated
-using a heuristic that is still changing (currently, it is updated when a new
-position significantly diverges from existing markers in the cache). Internally
-this is referred to as the skip list / fast search marker.
-
-### Deletions
-
-Deletions in Yjs are treated very differently from insertions. Insertions are
-implemented as a sequential operation based CRDT, but deletions are treated as
-a simpler state based CRDT.
-
-When an item has been deleted by any peer, at any point in history, it is
-flagged as deleted on the item. (Internally Yjs uses the `info` bitfield.) Yjs
-does not record metadata about a deletion:
-
-- No data is kept on *when* an item was deleted, or which user deleted it.
-- The struct store does not contain deletion records
-- The clientID's clock is not incremented
-
-If garbage collection is enabled in Yjs, when an object is deleted its content
-is discarded. If a deleted object contains children (eg a field is deleted in
-an object), the content is replaced with a `GC` object (*src/structs/GC.js*).
-This is a very lightweight structure - it only stores the length of the removed
-content.
-
-Yjs has some special logic to share which content in a document has been
-deleted:
-
-- When a delete happens, as well as marking the item, the deleted IDs are
-  listed locally within the transaction. (See below for more information about
-transactions.) When a transaction has been committed locally, the set of
-deleted items is appended to a transaction's update message.
-- A snapshot (a marked point in time in the Yjs history) is specified using
-  both the set of (clientID, clock) pairs *and* the set of all deleted item
-IDs. The deleted set is O(n), but because deletions usually happen in runs,
-this data set is usually tiny in practice. (The real world editing trace from
-the B4 benchmark document contains 182k inserts and 77k deleted characters. The
-deleted set size in a snapshot is only 4.5Kb).
-
-## Transactions
-
-All updates in Yjs happen within a *transaction*. (Defined in
-*src/utils/Transaction.js*.)
-
-The transaction collects a set of updates to the Yjs document to be applied on
-remote peers atomically. Once a transaction has been committed locally, it
-generates a compressed *update message* which is broadcast to synchronized
-remote peers to notify them of the local change. The update message contains:
-
-- The set of newly inserted items
-- The set of items deleted within the transaction.
-
-## Network protocol
-
-The network protocol is not really a part of Yjs. There are a few relevant
-concepts that can be used to create a custom network protocol:
-
-* `update`: The Yjs document can be encoded to an *update* object that can be
-  parsed to reconstruct the document. Also every change on the document fires
-an incremental document update that allows clients to sync with each other.
-The update object is a Uint8Array that efficiently encodes `Item` objects and
-the delete set.
-* `state vector`: A state vector defines the known state of each user (a set of
-  tuples `(client, clock)`). This object is also efficiently encoded as a
-Uint8Array.
-
-The client can ask a remote client for missing document updates by sending
-their state vector (often referred to as *sync step 1*). The remote peer can
-compute the missing `Item` objects using the `clocks` of the respective clients
-and compute a minimal update message that reflects all missing updates (sync
-step 2).
-
-An implementation of the syncing process is in
-[y-protocols](https://github.com/yjs/y-protocols).
-
-## Snapshots
-
-A snapshot can be used to restore an old document state. It is a `state vector`
-\+ `delete set`. A client can restore an old document state by iterating through
-the sequence CRDT and ignoring all Items that have an `id.clock >
-stateVector[id.client].clock`. Instead of using `item.deleted` the client will
-use the delete set to find out if an item was deleted or not.
-
-It is not recommended to restore an old document state using snapshots,
-although that would certainly be possible. Instead, the old state should be
-computed by iterating through the newest state and using the additional
-information from the state vector.
