Re:Comparing Mongo DB and Couch DB

You don't need to worry about the versioning for a document that you never update. You can just blast the logfiles into the database and not worry about conflicts. Similarly, database compaction is really the biggest concern when you're updating documents, not just dumping new ones into the database. I would expect a very linear growth for a logging app.

The problem doesn't come with the inserts, it comes with the deletes, where CouchDB will keep some metadata and stubs around to support its replication use cases. In a pure logging setup this is perhaps less than ideal.
ok, my initial thought was one document per logfile, containing an increasing amount of loglines, but that's probably the worst approach possible. One document per logline which is appended to the database should be much better.
