MongoDB's 2.5 GB limitation
Just as I was about do a test project using MongoDB, I am
informed by my host Webfaction that data on MongoDB will be limited to
~2.5GB only. It is not a limitation set by Webfaction, rather it is a
limitation in the 32bit version of MongoDB. What the hell?!
The MongoDB guys explains the reason thus:
"By not supporting more than 2gb on 32-bit, we’ve been
able to keep our code much simpler and cleaner. This greatly reduces the
number of bugs, and reduces the time that we need to release a 1.0
product. The world is moving toward all 64-bit very quickly. Right now
there aren’t too many people for whom 64-bit is a problem, and in the
long term, we think this will be a non-issue."
Whatever be the reason, I really wish MongoDB would remove
this limitation on the 32bit version, I don't think Webfaction is going
to upgrade ALL its servers to 64bit anytime soon. So conclusion is,
MongoDB is definitely not an option if you are looking to develop a data
extensive website - on a 32bit platform. So sad.
