:) np

We love Cassandra, and hate it at the same time.

Check out this nasty bug we got. https://issues.apache.org/jira/browse/CASSANDRA-13004

Two things are true about Cassandra:

It is by far the best at doing what it does

It has plenty of room for improvement

You are 100% right that it is the best at what it does.

And thank you again with helping us with that bug :) we really appreciate it.

I'm currently far down the database rabbit-hole and have to ask: What's so great about Cassandra that you can't get with CouchDB or other AP (yeah, I know...) databases?

Solid ingestion story. Very very good write throughout. Linear scaling. Easy expansion / contraction. Complete flexibility in consistency vs availability tradeoff.

And most importantly:

It actually works at scale. Huge scale. Thousand node cluster and hundreds of thousands of instances scales.

Because a good chunk of the active maintainers actually run this shit in prod.
