Apache Cassandra Consulting & Support for Enterprises

Our Cassandra consulting covers query-first data modeling, partition key design, multi-datacenter replication architecture, compaction strategy selection, performance tuning, and migration planning. Every engagement is staffed by a named senior engineer with production-proven Cassandra expertise.

A poorly chosen partition key concentrates writes onto a small number of nodes, creating a hotspot no amount of hardware or tuning can fix without a data model change. We model tables around your actual query patterns before any code is written, not after a hotspot shows up in production.

It depends on your read/write ratio and update pattern — Size-Tiered for write-heavy workloads with few updates, Leveled for read-heavy workloads that need consistent latency, and Time-Window for time-series data with TTL-based expiry. We match the strategy to your workload rather than defaulting to STCS.

Yes. This is one of the most common reasons teams move to Cassandra. We denormalize the schema around your query patterns, design the partition and clustering keys, and run a dual-write cutover to validate data integrity before decommissioning the old system.

A Cassandra healthcheck covers partition size distribution, compaction backlog and SSTable counts, repair history and consistency risk, and node capacity against ingest growth. We deliver a written report with prioritized remediation steps.

We start with nodetool status, hinted handoff backlog, and GC pause frequency to isolate the problem layer, then move to immediate stabilization and root cause analysis. We stay engaged until the cluster is fully recovered and the incident is documented.
