So what about our view on Cassandra vs MongoDB?
They both are enormously scalable, high-performance databases belonging to the NoSQL family. Yet, these two are radically different.

Cassandra database is designed to manipulate huge data arrays across multiple nodes.

MongoDB database stores data in the form of JSON-like documents instead of table records used in relational databases. It allows faster data integration.

What's your vision of Cassandra and MongoDB? Which one would you choose and why? 😏

[DataStaxDevs]

3:03 is not perfectly correct. Cassandra doesn't have "Multiple master nodes", Cassandra has no master nodes as it's masterless. Besides that, great comparison!

[paulkre]

2:17 is wrong. MongoDB is actually ACID-compliant by default. You can use MongoDB in a BASE-compliant way, but it requires configuration.

Cassandra is not columnar, it is column family, but it's NOT column-oriented, Cassandra organizes data by rows. Also columnar dbs can guarantee faster data retrieval in some cases, but in some cases it is not true. Way too many inaccuracies

I would have liked more in depth discussion on the write speed. Why would cassandra be a better option for writing huge amounts of data? Is it because of the no-master architecture of cassandra? Is it because all writes in mongo DB go to one leader node? Then it should also be mentioned that for high write throughput in cassandra it is important to select the correct write quorum.

In the comparison with sql you stated, that mongodb is horizontally scalable while sql databases aren't. That's just not true. If you see master-slave model as a horizontally scalable then a lot of sql databases are too, because they use the same model (postgres for instance).

Great video! But MongoDB 4.4 is ACID complaint :-)

Great Video was not sure whether I can understand in just 5 minutes, but boom..you make it

[SP-dbsh]

It's 2023, &high time to make a python implementation version of it !
Thank you....

This video is concise but informative!

So Cassandra is better for Facebook, Reddit, and Twitter. MongoDB for websites without comments.

Thanks. Short and excellent explanation.
