# Document Resource

A Sync Document is an object with these characteristics:

* It's a single JSON object, up to 16KiB in size.
* Its modification history is not maintained; however, documents are assigned a new revision number after each modification.
* Its concurrency control is based on an 'eventual' model and it uses revision numbers for conditional updates.
* It expires and is deleted automatically if its eviction is configured by setting the `ttl` parameter. By default, it is persisted permanently.

## Working with Sync Documents

A Sync Document is best suited for basic use cases, such as rudimentary publish/subscribe flows, or situations where history synchronization is not a requirement.

Documents can be created, updated, subscribed to, and removed via the client [JavaScript SDK](/docs/sync/quickstart/js). See the latest [JavaScript SDK](/docs/sync/javascript/changelog) documentation for full details. Servers wishing to manage these objects can do so via the REST API.

## Document Properties

The `mutate` function helps your JavaScript code respond to concurrent updates with versioned control. See the corresponding [JavaScript SDK](/docs/sync/javascript/changelog) documentation for details.
