Cassandra and DataStax Consulting
Wide-column scale without a resident Cassandra expert.
contact us nowCluster & Data-Model Review
We audit your schema against real access patterns — partition sizing, tombstones, secondary-index misuse — plus compaction, repair posture, and driver configuration, and hand you a remediation plan ranked by production risk.
Design & Build
Query-first data modeling, driver integration, multi-datacenter topology design, and capacity planning for new Cassandra and Astra DB workloads — tables designed from the queries backward.
Migrations & Upgrades
Major-version upgrades across the 3.x, 4.x, and 5 lines, DSE and open-source moves in either direction, self-managed to Astra DB migrations, and zero-downtime dual-write cutovers.
Operations Retainer
Repair and compaction hygiene, monitoring that catches problems before your pager does, incident escalation, and performance tuning — by the hour, as much or as little as your cluster needs.
Query-First Modeling
Most Cassandra pain is relational habits carried into a wide-column store. We design tables from the queries backward, so partitions stay bounded and reads stay fast as data grows.
Operational Depth
Repairs, compaction strategies, and upgrade sequencing are where clusters live or die. We have run them enough times to know which defaults to trust and which to change on day one.
Straight Answers on Fit
Cassandra is superb for high-write, always-on workloads — and wrong for plenty of others. If your problem is better served by a different store, we will say so before you spend on the wrong architecture.
