Limitation of MongoDB in 32 bit OS
Fellas, There are many limitations of 32 bit OS, if you want to install MongoDB on that machine. This situation has been faced by many people and later on they realise they need to upgrade their system or use MongoDB in Development/Test Environment only for that machine.
Limitation of 32 bit OS for MongoDB installation
1. Max Database size can be of ~2 GB.
2. Your data will be in inconsistent state, if your database crash untimely. Since, By Default Journal is disabled in MMAP Storage engine with 32 bit OS, so that you will have enough space to store your database. If you enable Journal, it will take ~1 GB of size and data directory of your database will have ~1 GB of size only, which will be another limit of database size.
Though now all the systems are coming with 64 bit OS, so you won’t have problem like this.
But if you have 32 bit OS, then use MongoDB in that machine for Development/Testing purpose only.
