Spent the last month creating a really scalable chat application, with fast front end, all kinds of neat functions such as polls, and a really efficient database structure in Apache Cassandra.. Everything is built to use NoSQL, and even the front-end is using all kinds of features to speed up itself... Now, guess what... The company I'm doing an internship decided that everything needs to be done in MariaDB, and I can basically remove 1/3 of my program, event the front end will get a huge purge of code, and as much as I explained that MariaDB IS NOT FUCKING USABLE FOR A CHAT APPLICATION, and when there are many messages, the access times will get realllllyyy sloow, and that the whole structure there currently is based on NoSQL... Now I can remove all the clustering, custom data types, and bucketing of messages... And store FUCKING JSON IN 'TEXT' FIELDS IN A STUPID SQL DATABASE. FUCK ME

Marketing department sometimes are so Fucking annoying in the context of they " just found out certain technology" and try to enforce us to implement.

For example recently this guys just found out firebase(Firestore thingy ) and keep asking us to implement into the app (E wallet app) which our software architect refuse to use firebase( I agree with him) because in the long run , the project will definitely get surprising prices in the invoice.

Also, our DBA had started to implement Apache Cassandra .....

So dear marketing department, why don't you guys shut up and let us do our job and let our software architect do his job? Fuck off!

FUCK AWS KeySpaces pretending to be Apache Cassandra Compatible!

One of the things that gives me a lot of satisfaction is doing integrations. One customer has a good architecture, and they chose to put their metrics database with billions of records in Apache Cassandra. Which is pretty cool! A business consultancy that is helping them grow a lot, has implemented PowerBI and the dashboards are really good, but the most important reports will be based on this gigantic Cassandra database. We just delivered a quick integration using Apache Spark. Small project, fast delivery and everyone happy. Is so good. Mission accomplished feeling.

Thoughts on Apache Cassandra? Seems awesome, but are there any gotchas we should know about before diving in? Currently we use Postgresql for most things.
