How does sync work?

Collaborate using Channels

•For each document, you specify a set of channels it belongs to

•For each user or device, you control which channels they can access

•Replicate only a subset of documents down to the device­ User-defined filter functions

­ Simply lets you know whether a document should be replicated

•And you can authenticate users

各ドキュメントにチャネルを設定

ユーザまたはモバイル端末に対し、チャネルへのアクセスを制限

全ドキュメントの中から（チャネルに関連付けられた）ドキュメントのみを複製
