6 points · Open discussionProud to see my name (https://twitter.com/YingjunWu) mentioned in Andy's blog. I was Andy's visiting PhD at CMU and was the top 1 contributor to Peloton (https://github.com/cmu-db/peloton).
Today, building a database from scratch is extremely difficult, for several reasons:
1. it anyways takes a long time;
2. there are so many successful (open-source) databases;
3. hiring top engineers are so expensive.
4. you won't get enough attention unless your system is drastically better than existing ones.
An interesting observation is that very few database was built since 2020 - almost all the newly built databases were developed on top of existing databases (PostgreSQL, ClickHouse, etc).
I started building RisingWave (https://github.com/risingwavelabs/risingwave) in early 2021. The only reason we built the system from scratch was that none of th
Read the rest
e existing systems can address the problem we are solving - distributed SQL stream processing at cloud scale. We tried Flink but gave up, as it's too heavy and it's architecture was not designed for the cloud environment.
If you want to build a database from scratch, or are simply interested in databases, we may talk.
I'm very interested in such products. It appears to be similar to Materialize DB.
I use dbt and Postgres for managing a data warehouse. It appears Risingwave doesn't have support for dbt yet, there is an open issue [1]. Materialize supports dbt. Materialize also offers Postgres wire compatibility i.e. I can connect to the Materialize using Postgres drivers. I wasn't able to find this information on Risingwave yet.

15 points · Open discussionPlease also take a look at https://github.com/risingwavelabs/risingwave if you are looking for advanced streaming databases. It is under Apache License and also support on-prem deployment (docker, kubernetes) with full function set of distributed clustering, compute-storage disaggregation, etc..
Let me know if anything.

2 points · Open discussionRisingWave is a cloud-native streaming database
1 points · Open discussionWe have just open sourced RisingWave, a cloud-native streaming database that uses SQL as the interface language. RisingWave is designed to reduce the complexity and cost of building real-time applications. It consumes streaming data, performs continuous queries, and updates results dynamically. As a database system, RisingWave maintains results inside its own storage and allows users to access data efficiently.
