About
Specialists in one hard database.
RapidMindLabs is a US consulting firm that does one thing: Apache Cassandra and the DataStax ecosystem — DataStax Enterprise and Astra DB. Data modeling, cluster operations, migrations, and upgrades, for teams running high-write, always-on workloads without a resident Cassandra expert.
Why a specialist firm
Cassandra is not hard because it's obscure — it's hard because it inverts habits that serve engineers well everywhere else. Normalize your data: wrong. Add an index: usually wrong. Let the database plan your query: there is no planner to save you. The teams that thrive on Cassandra are the ones that adopt its discipline early, and the fastest way to adopt a discipline is to work alongside someone who already has it.
Generalist shops treat Cassandra as one more database. We treat it as the whole job — which is why we're comfortable saying that repairs, compaction, and partition design are where the real work is, and why we'll also tell you when Cassandra isn't the right store for your problem at all.
What working with us looks like
Senior US engineers, billed hourly, working in your repositories and your monitoring under your access controls. Reviews run read-only and end in a prioritized written plan. Migrations get rollback points at every phase. Everything we do is documented and handed over, so your team gets more capable with every engagement rather than more dependent.
Where we focus
- High-write, always-on systems: IoT telemetry, messaging, personalization, time-series
- Cassandra 3.x through 5, DataStax Enterprise, and Astra DB
- Multi-datacenter topologies and the operational discipline they demand
- New in the 5.x era: vector search workloads on Cassandra's native vector types
