Dear Wiki user, You have subscribed to a wiki page or wiki category on "Couchdb Wiki" for change notification.
The following page has been changed by JasonDavies: http://wiki.apache.org/couchdb/History New page: = Proposal for CouchDB history support = * We will use a separate database to store history documents. * The main change will be at the couch_db level in the document update functions, so that *any* change to a document will be recorded in the history database. * Changes to documents will result in a new document being written to the history database, of the form: {{{{ _id: <uuid>, doc: { <original document> } } }}} * The history database is an ordinary CouchDB database that can be manipulated as normal e.g. views can be added to organise the history docs as required. * If people need to add meta-data to the history, e.g. "last changed by", "last changed date/time", then the recommended way would be to use a custom _update handler to add these fields to the doc being saved, and these would propagate to the history database.
