Logging document changes to file system

[Robert Labrie]

I might have to make this, but I decided to ask first. Is there any way to write out a document to the file system every time it changes? So if I had something like "people/robert" whenver it changed, it'd get written out to "C:\docs\people\robert.yyyyMMddhhmmssfff.json"?

What is the goal for doing this?

Would the versioning bundle be more appropriate?

The best way to achieve this would be to use Subscription 

see:

http://ravendb.net/docs/article-page/3.0/csharp/client-api/data-subscriptions/how-to-create-data-subscription

and add the writes to the FS in the handler.

I think forking the versioning or replication bundles would likely be a better starting point.

[Robert Labrie]

Hi, thanks for your replies. The purposes are mainly for troubleshooting applications which are backed by Raven, so that we can see the shape of documents that change when users report issues. Currently I use a scheduled task to just grab the document once a minute. So there is no existing feature, but you say the replication bundle would be a good starting point? I'm guessing there is some sort of hook mechanism I can get whenever a document is written?

[Kijana Woodard]

You could say that the versioning bundle is such a feature.

Every version of the document is kept.

Except for the requirement to write on a filesystem the changed documents, I'd say it sounds very much like versioning bundle.

Is there a reason to write them on a filesystem, and not store their revisions in a database as separate documents?

Best regards,
