TITLE: Viewing Collaborative Editing Through a Databases Lens
ABSTRACT:
Software that allows several users to collaboratively edit a document, such as Google Docs, has traditionally been ignored by the databases community. This is surprising, because managing the edits to a text document, spreadsheet, vector graphics file, etc. is very much a data management problem, albeit with a data model that is very different from that supported by most databases. Collaboration software needs replication, concurrency control, and data layouts for efficient storage and retrieval.
In our work on Automerge, a CRDT library for building collaborative software, we have been taking concepts from databases and applying them to the domain of collaborative editing. In this talk I will show how column-oriented data formats, multi-version concurrency control, log-structured storage, and other ideas from databases can be used to make collaboration software better.
