MongoDB CTO: How our new storage engine will earn its stripes

BDB... seriously?<p>At this point why not just:<p>apt-get install postgres psql &lt; &quot;CREATE TABLE mongodb (key varchar[1024] NOT NULL PRIMARY KEY,value jsonb);&quot;<p>then you get the best of both worlds.

I&#x27;m not a huge MongoDB fan, but I think it is great to see competition and evolution in this space.<p>From the article:<p>&quot;In addition to compression and record-level locking, WiredTiger also gives MongoDB multi-version concurrency control (MVCC), multi-document transactions, and support for log-structured merge-trees, or LSM trees, for very high insert workloads&quot;<p>I&#x27;d also love to see them add document joins at some point. That&#x27;s a a big differentiating feature for RethinkDB, although I&#x27;ve found Rethink&#x27;s syntax to be difficult to reason through.

Here is a link to some more &#x27;thorough&#x27; benchmarks that compare WiredTiger to many other database back-ends.<p><a href="http://symas.com/mdb/inmem/" rel="nofollow">http:&#x2F;&#x2F;symas.com&#x2F;mdb&#x2F;inmem&#x2F;</a>

But the old one is crap, right?

I am glad they finally introduced LSM trees and per document locking. But I think thats too little too late :-)

I have been waiting for this since a long time. Having implemented an OLTP application using MongoDB (luckily their write loads were low), I stopped using Mongo 2 years back because of the write bottleneck (it was still good for OLAP though). Good decision by the MongoDB team since they already have the market traction.
