ClickHouse achieved good (great) results. However, it's a bad comparison. Clickhouse is an analytics DB while Scylla is a realtime, random access one. /me am Scylla co-founder. We could stack 100k rows in a single partition and be

To some extent yes. It's not 100% protection. AGPL is just the right model, closes the loophole that GPL left. If you get to change the code, you must contribute the changes back. That's all

Kudos for AWS for the ability to launch so many services, many of them are competing with each other or complimentary. At first I (disclosure, ScyllaDB co-founder) called their serverless a bluff but I gave it a try and it's nice to cr

Pls let us know what you think about the results!

Agree it's annoying (I'm one of the co-founders) but it's the minimal 'eval' to make sure users succeed to maximize the value from their downloads. We mainly push them to slack and to share monitoring and logs with

My claim is only an assumption. However, after our experience with not reaching the reserve limit plus the example they provided that didn't scale to a million of iops lead my to this guesstimate. We on the other hand have plenty of ex

The benchmark was done as fair as possible but I'm the vendor, yes, don't take my word (despite good background in OSS and earlier achievements). Listen to our users: - Here's a webinar by one of our customers explaining how

There are tons of limitation on the on-demand, certainly it cannot go to extent of 120k ops. Check their example, they toy with a tiny workload.

True. In our brand new service offering we took it all into account. Networking is costly but doesn't change the game that much. Scylla is 4x-6x cheaper, depending whether it's on-demand (vs Dynamo on-demand) or reserved for a yea

It may work at the price of 4x which is already 7x higher, resulting in 28x total.. not to mention the hassle. Man, give us a try. Seen your comment about LWT, agree.. We knownly chose the first make MV/SI great before committing to an

I went and run a ping between 2 VMs, one on us-east1c and the other on a different AZ - us-east-1b As you can see, the ping latency is 0.5ms to 1ms on rare occasions. Of course that ping has a cost even within a single AZ so the above numbe

You're right, thanks

I don't think this is the case - check this link: https://knowledgebase.progress.com/articles/Article/expected... The intra AZ latency according to AWS is sub millisecond! It's inline with what our custo

About multiple AZ, I think we haven't used it in this case but it shouldn't change a bit, most of our AWS customers have AZ-aware deployments and it works great. Since I see you're with AWS, you're welcome to help us deb

Fair questions, let me (Dor) answer: 1. Scylla works within different AZs too We are topology aware and can have as good and even better HA than DynamoDB. Our design is based on C* 2. We were surprised with getting small utilization

It's not abandoned, we continue to maintain and contribute to it but sadly, it's not our business focus in the present. I really want to see it to win centerstage one day in the future. Few orgs do use it in production. It's

From the link: "A 3 node Scylla cluster executes 4.6X more OPS than a similar Cassandra cluster. Only a 30 node Cassandra cluster can level the throughput of the Scylla cluster of 1/10th the size. Yet the 1:10 gain is not the end
