MongoDB 1.4 Ready for Production
The MongoDB team is very excited to announce the release of MongoDB 1.4.0. This is the culmination of 3 months of work in the 1.3 branch and has a large number of very important changes.
Many users have been running 1.3 in production, so this release is already very thoroghly vetted both by our regressions systems and by real users.
Some highlights:
Core server enhancements

MongoDB 1.4 Performance
We generally avoid posting benchmarks and suggest people create their own targeting their use cases. However, we have decided to publish a few of our internal micro-benchmarks comparing 1.2 with 1.4RC2 (aka 1.3.5) to show that in almost all cases performance is the same or better (sometime significantly so), even though we’ve added many new features.
The test works by spawning N threads and...

Check out the 10gen blog for a good recap of NoSQL Live Boston.
Should MongoDB Use SQL as a Query Language?
MongoDB does not use SQL as a query language. Why not? This is a very good question and we have discussed it on the project for a long time. There are a few reasons for this.
Given the document-oriented nature of the storage, if we were to do SQL, it really world be a variant, not true SQL. There would be no joins, and we would need extensions to handle the nested constructs involved in JSON...
State of MongoDB March, 2010
Every once in a while, I think its important for us (the core MongoDB team) to give a broad picture of where we think MongoDB is and where we’re hoping to take it. This is useful both as a gut check for us, to give the community some insight into what we’re thinking, and to make sure we’re all on the same page.
MongoDB has made great strides in the last year. The first public...

2d geospatial indexing

Would love to get some feedback on features people would like to see, how its working, etc…
