Cassandra Database Crash Course

In this video, I will go over the basics of one of the most popular NoSQL databases, Cassandra. Cassandra is an always available, distributed, NoSQL database.

At first I will go over the features of Cassandra. From there, we are going to dive deeper and see how a read and write path works in Cassandra. Finally, we are going to go over how to design data models in Cassandra effectively. Then, we will wrap up with some good use cases of Cassandra.

I talk about all the different features of Cassandra and how they are beneficial. It’s a good introduction to Cassandra, if you want to use this database in your next application.

Here are some good resources that I wrote that will help you understand Cassandra better:

I link this video to anyone who is beginning with Cassandra. You have the most clear and concise explanations available online. Thank you very much for your work!

11:50 let me clarify, this is a very compound PRIMARY KEY <PARTITION KEY, league, kit_number, position, goals> with a PARTITION KEY <name, club>?

Thanks for your work. To be true the commit log (who acts like a REDO log) resides on disk and not in memory. Thanks again! :)

I am now on course to crash a Cassandra database.

6:47 so a write goes to all partitions or just one? You didn't mention this. If only one partition receives the write, is it written to disk before committed back as successful to the caller or how does this work?

When the data is still in Memtable and not yet sent to SSTable and server crashes (or say power goes off), we loose data right? What happens in those cases? Any way to recover data?

[mpaltanwale]

Commitlog is on disk and not in memory, if you want to make correction in the video.

It was so easy to understand! Thank you!

[tianqizhang]

Great explanation, easy to understand!

[josedamianjimenezn]

Very clear your explanation!, Now I can see that cassandra is a good option to consider as DB in my project, thanks a lot for this useful content!

[dineshkuruba]

great video, please do a video on how the data is stored on disk with different column families

[unujjwal]

Mentioning the consistent hash ring should be a necessity for intro to cassandra videos

[breaknbroke]

Is a distributed database all you need for a system to be distributed?

[Entertainment_Zone]

Bro can you please make video on zipkin traces Store in Cassandra database
