Next-generation database technologies

Columno is a novel approach to relational and NoSQL databases that reduces the learning-curve for developers while drastically improving performance and cost.

What is Columno?

Columno is an on-the-fly "translator" between relational databases and NoSQL databases.

The Best from Both Worlds

Well-known SQL interface currently with PostgreSQL support (no need to change sourcecode/no new libraries).
High scalability and very low cost with NoSQL (Redis, Azure Table Storage coming soon).

Employ New Technology with Zero Experience

Like to use the lastest in-memory databases along with a scalable and cheap key-value store? You will be able to cross-join, insert, update, ... in NoSQL DBs from your standard framework (ORM).

Cloud or On-premise

Columno Cloud manages everything for you. Just select the NoSQL DBs you would like to use, point to our database and you are up and running.

Why is it so cheap?

Many NoSQL databases are rather simple concepts compared to traditional databases. With NoSQL databases you typically don't pay to run an instance. You only pay for what you use or provision.

Where's the index?

Everything is stored in the NoSQL DBs. No information resides permanently in the Columno program. This makes Columno more fault-tolerant and scalable.

What language and when is the next release?

Currently, Columno Cloud it's a mix of C++, C# and Python. The core NoSQL translation is currently done in our cloud-service. In August 2020 it will all be done within the C++ program. We aim at releasing a new version every month.

Is CockroachDB, CosmosDB, Aurora better?

Many modern scalable databases exist, often categorized as NoSQL or NewSQL. Most of them are awesome. Columno is a different approach — we seamlessly let you choose where to store data. You can, e.g., choose Redis for some data and DynamoDB for other ― all from the same DB connection with the SQL interface you know.

What's the overhead of all this?

The transformation from relational data into a key-value store doesn't come for free. But key-value stores are fast, very fast — and with a lot of effort we can get extremely good performance.

I'm King of NoSQL ― why this?

Are you (and your colleagues — and the one taking over from you ) experts in NoSQL DBs and do you know how to easily map all of your data and objects so it's all efficient and scalable — then Columno is a waste of your time. But give us a call when you don't have the time anymore :)

Beta 0.3.0 does not sound very mature?

That's because it isn't. We still have very limited functionality but we will grow up fast! We are very focused on performance, stability and high-quality source-code.

Will it be faster?

Yes! Right now Columno Cloud a mix of different programming languages and not optimized towards performance. In August 2020 we will switch from Columno Cloud (our first prototype, v. 0.1) to the C++ program and then you will see improved performance.

SQL and relations sound oldschool to me?

NoSQL (or better: NoREL) was pretty hot 10 years ago when people wanted scalability and distributed data. However, SQL (and relations) is here to stay — just look at all the new databases, they all want to fuse SQL, relations, scalability and distributed data.
