Hi Nils, I am using Python to have 2 separate background process that: 1) Replication connections are working/ restart/ fix if needed (including wrapper SSH tunnels). 2) Conflict resolution that is triggered by the _changes feed, asynchronous and parallelized.
I've also used CouchDBKit to manage CouchDB from Python. Doing the response/fix logic in a cron triggered script proved problematic for me, so I went and added my own scheduling bits, on the way enabling sub-minute precision quite easily, attributing to the fun and ease of Python. (Scheduling being mostly while loops with configurable sleep intervals, at its simplest form, and time/date based sleeps) Being able to suspend interval triggered execution until a previous run came back, without having to use locking or flag files and such as when using cron, was a breeze. I guess that is "different" not better perhaps. -Sivan On Mon, Jul 26, 2010 at 11:57 PM, Nils Breunese <[email protected]> wrote: > Python is a programming language, not a scheduler.
