That's not true. Scylla does multi-threading. Scylla is a single process, single address space. It does pin the threads to individual hyper threads but there are additional other w…

Many need SVB, we (ScyllaDB) received a great service from them in the past. Later on we just used them as one of our banks, obviously, going forward, we're diversifying our servic…

ScyllaDB uses AGPL, a good and valid license

There is no magic behind Scylla, mainly lots of hard work, hundreds of years of engineering, based on the former C* design which is based on Dynamo/Bigtable. The JVM is part of the…

We (I'm a co-founder) run the following: - 1B (10^9) rows/sec with 86 servers https://www.scylladb.com/2019/12/12/how-scylla-scaled-to-one... - 1PB with 20 servers https://www.scyl…

Listening to SQLite creator podcast ( https://corecursive.com/066-sqlite-with-richard-hipp/# ), it does feel that Glauber is right about weird collaboration standards. The guy is a…

This is indeed what we (ScyllaDB) do, pretty much everywhere. It works great for 95% of our users. Discord wanted to add a level of guarantee since they observed a too high level o…

Am ScyllaDB but Marc did completely independent work. The client vcpus don't matter that much, the experiment compares the server side, the client shouldn't suck. When we test Scyl…

Good point. This is more of a tcp stack comparison between the kernel and userspace. Seastar has a sharded (per core) stack, which is very beneficial when the number of threads is …

What's amazing is that the seastar tcp stack hasn't been changed over the past 7 years, while the kernel received plenty of improvements (in order to close the gap vs kernel bypass…

ScyllaDB uses Seastar as an engine and the DynamoDB compatible API use HTTP parsing, so this use case is real. Of course the DB has much more to do than this benchmark with a stati…

Impressive stuff! Worth to try to run the OSv unikernel (one of my babies) in it.

Indeed quite a journey. If you love DynamoDB and like open source, give Scylla a try (disclosure me==founder): https://www.scylladb.com/alternator/

It's not the open source license which we can't forbid using, it's the enterprise version.

Hmm, AGPL is proprietary? This isn't aligned with the OSI.

Clickhouse and other solutions you mentioned are for analytics while Scylla and Cassandra are for real-time. You can't compare the two types of tech
