Writeup on MongoDB Meetup at Jabong

IMG_1557Mongo Dilli (meetup url) held its meetup at Jabong on Aug 22, 2014. We started around 6:15 after initial introduction of participants. At least a quarter of them were using MongoDB in production, while few had just started looking at it. About half of them had not tried MongoDB yet, but were extremely interested in it.

The first talk was by the hosts at Jabong, Supreet Sethi and Apoorva Moghey. They had audaciously run MongoDB on Raspberry Pi running ARM processor. Since MongoDB runs on small Endian machines till MongoDB Inc fixes SERVER-1625, they had to use download a fork (github url) of MongoDB and compile it.

While they were presenting, I was frantically trying to finish up presentation. I tried rigging the raffle bucket, but it did not work, as I did not win it at the end just kidding :)!IMG_1558

After this, I started with my talk on Product Catalog: Retail Reference Architecture with MongoDB. After all, I was at Jabong, India’s leading e-tailer! On a serious note, the schema design in MongoDB due to its document structure is different compared with relational ER modeling, so I chose a sample domain to illustrate general points. I did spend quite few minutes on answering general and introductory questions on MongoDB, nosql; because 50% of audience was new to MongoDB and a few entirely fresh to nosql.

After this Anuvrat Prashar from product review portal, Zopper presented his journey of Python and MongoDB. It was really a pleasure to listen to the nerdy talk. Interestingly, he had ssh’ed to his box from his colleague’s over the internet, as his machine did not have a connector to the projector. His presentation was HTML5 and transitions were taking time after action, but things worked fine. We learnt a big deal about Python MongoDB driver and a few wrappers on it. The crawling produces semi-structured data, which is easily digestible by MongoDB. It would be a nightmare to do the same on a relational database.
