Major Discussions

Writing many docs at once: bench marking a 10k write to a CouchDB server (see thread here)

A discussion around handling and measurements of bulk input in CouchDB.

Question about “complex” range queries (see thread here)

Requirements for sort orders of data views.

Is the revision field deterministic? (see thread here)

Quoting Robert Samuel Newson’s reply: “Yes, it’s deterministic. The same document with the same history will have the same _rev value. This is an optimization over the previous algorithm where _rev was a random UUID. […] The advantage is that two servers receiving the same update can more optimally replicate. They still have to check that the target has all _id/_rev pairs but will usually be able to skip actually transmitting document and attachment content.”
