Hey, Chefs –
As we’ve rolled out Chef to larger and larger sites, I’ve discovered that
CouchDB is a significant scaling problem. The time to compact the database
and views has risen (and risen, and risen), and search performance has
declined. I’ve heard rumblings that Hosted Chef is no longer using Couch
as it’s backend, which suggests that Opscode might have hit this pain as
well.
There’s obviously some tuning that we could do to Couch which would make it
behave better, but I need to scale it to approx. 40x what it’s currently
doing in order to roll out Chef to the remaining sites in my environment,
and I’m extremely skeptical that anything – even the most aggressive
tuning – will make that work.
I’m wondering a few things:
-
Are there existing branches of Chef (within Opscode or otherwise) that
aim to replace CouchDB with another database (be it a document-based store
or something more relational)? -
Are any of those branches public, or are there plans to roll those
changes into the open source version? -
If those branches don’t exist, how much interest is there on the list
in removing the dependency on CouchDB? Would other people be interested in
participating in a project like that? -
