Subject Introducing Iron Cushion, a benchmark and load test for CouchDB
Date Sat, 31 Mar 2012 21:42:07 GMT
Hi all,

Last week I searched for CouchDB benchmark and load testing suites. I
only came up with three-year old blog posts containing one-off scripts
or tests for read performance using ab, and the Definitive Guide
itself ( didn’t allude
to anything good.

So I went ahead and wrote one called Iron Cushion, which you can find
available at It proceeds in two
steps: First, documents are bulk inserted using CouchDB's Bulk
Document API. Second, documents are individually created, read,
updated, and deleted with random ordering of operations using
CouchDB's Document API. Detailed statistics for both steps are printed
at the end.

You can specify the number of concurrent connections to the database,
a “schema” for documents inserted and updated, how many documents to
bulk insert, how many CRUD operations to perform, and lots more. More
information can be found on the GitHub page.

(Disclaimer: Absolutely no warranty, don’t accidentally bulk insert a
million documents into your production DB, etc.)

All sorts of feedback is welcome!
