As a follow up to the MongoDB positioning itself as Big Data and development agile environment, I’ve found this bit of data on Curt Monash’s blog:
The biggest clusters they came up with weren’t much over 100 nodes, but clusters an order of magnitude bigger were under development. The 100 node one we talked the most about had 33 replica sets, each with about 100 gigabytes of data, so that’s in the 3-4 terabyte range total. In general, the largest MongoDB databases are 20-30 TB; I’d guess those really do use the bulk of available disk space.
I guess neither of Wordnik or Foursquare which were mentioned in the comments are the largest deployments.
