ScyllaDB, a company that develops an open-source NoSQL database, has announced that it has raised $43 million in a Series C3 round of funding, bringing its total funding to $100 million.

The funding round was led by Eight Roads Ventures and AB Private Credit Investors, and also included TLV partners, Magma Ventures and Qualcomm Ventures.

ScyllaDB’s database is based on the open-source Apache Cassandra database, but claims to offer more scalability and performance. ScyllaDB’s database can also replace the Amazon DynamoDB database, and aims to compete with the MongoDB database. ScyllaDB’s database can be deployed in different ways, such as open source, enterprise, or cloud database-as-a-service.

ScyllaDB is currently working on its next major release, ScyllaDB 6, which will introduce a new feature called tablets. Tablets are small chunks of data that can be distributed and balanced across the available computing resources. Tablets will enable faster elasticity, which means that the database can quickly add or remove capacity for different workloads.

ScyllaDB 6 will also use Raft consistent metadata, which is an open-source protocol that ensures data consistency across distributed clusters. Raft consistent metadata will allow multiple database schema and topology changes to happen in parallel, rather than one by one.

While much of the database industry is increasingly chasing generative AI workloads, typically by supporting vector embeddings, that’s not a direction that ScyllaDB is taking, according to VentureBeat.

Datastax, which is among the leading contributors to the Apache Cassandra database, recently added vector support to its commercial database and contributed code to enable vectors in the open-source project. MongoDB is now a competitive target for ScyllaDB and also supports vectors as it aims to support generative AI.
