Rockset boosted by $ 40 million Series B venture round

Rockset, the data platform, which positions itself as a high-performance indexing level for analytical queries, has been taken in an additional $ 40 million round of B funding, bringing the total to $ 61.5 million. And the provider, which exclusively offers its indexing platform as a cloud-based service, adds support to run its platform inside a customer’s own VPC in the AWS cloud.

As we wrote back in 2018 when we introduced the company, Rockset was founded by a Facebook alum who built social graph. It is a cloud-based service that offers a high-performance, serverless indexing degree to relieve complex queries from data warehousing and search platforms. Build on RocksDB, an open source, log-based key store with an engine written in C ++, Rockset incorporates what it calls a “converged index“, which combines column index and search index properties. In the Rockset engine, each column is indexed, both in a column index and an adjacent search index, where the platform’s SQL query optimization tool runs in a C ++ engine that selects which one to use.

The result is a platform that performs a role similar to Redis, which adds a high-performance level of memory to read queries to hot data. The differences, of course, are that when Redis was used as a caching level, it is better suited for lookups rather than analytical queries involving complex SQL logic. (As a database, it is more suitable for apps that take advantage of Redis modules.)

Rockset is not intended for implementation with petabyte-scale data lakes. Instead, it is aimed at speeding up complex queries on well-defined datasets. And then it has seen a significant uptick in the last year Snowflake, MongoDBand DynamoDB customers. In these cases, it does not replace these databases, but instead relieves selected workloads. That typical use case for NoSQL platforms just as DynamoDB and MongoDB provide an analytical query level. For Snowflake customers, it speeds up and lowers the cost of workloads that would otherwise require more EC2 consumption. In both cases, Rockset populates indexes using change-data-capture streaming feeds from source databases.

As a cloud service operating in AWS, data is typically stored in multi-device S3 storage. This is where the just announced VPC feature comes in; it provides a way for the Rockset service to operate on data within the customer’s own AWS VPC. It is targeted at SaaS services that build into Rockset’s features or companies with sensitive PII class data.

With the new venture round, the 30-person company looks set to double the number of employees over the next 18 months, triple sales and marketing teams and double the product engineering group.
