Craigslist replaces MySQL with MongoDB

According to foreign media reports, Craigslist, the world's largest classified information website, is using the MongoDB database to archive data. Previously, the website used a MySQL database cluster. This is perhaps the largest website using NoSQL data storage.

 

The following is the MongoDB cluster for Craigslist, Zawodny, a software engineer from the website:

We are calculating the space for installing about 5 billion documents, from the first 2 billion documents, and adding the space needed in the next few years. The average size of a document is 2 kb and 10 TB in total ). We are exploring MongoDB in practice. This special task is not about high throughput or unpredictable growth.
Importing data to MongoDB during migration is faster than exporting data from MySQL.
