Apache Cassandra Consulting & Support Services

Nextbrick provides Apache Cassandra consulting and Apache Cassandra support for architecture reviews, data modeling, performance tuning, migrations, and 24/7 production operations.

Distributed Database Architecture

Apache Cassandra is purpose-built for workloads that demand zero-downtime availability and linear horizontal scalability across data centers and cloud regions. Nextbrick's Cassandra consultants design cluster topologies that leverage Cassandra's masterless, peer-to-peer architecture to eliminate single points of failure while delivering consistent low-latency reads and writes at massive scale. We help organizations select the right replication strategies, snitch configurations, and consistency levels to balance availability, durability, and performance for their specific use cases.

Our architects specialize in data modeling for Cassandra's wide-column store—designing partition keys, clustering columns, and materialized views that align with your application's query patterns. Unlike relational databases, Cassandra demands query-first modeling, and Nextbrick ensures your schema delivers optimal performance without the anti-patterns that lead to hot partitions, tombstone buildup, and read latency spikes.

DataStax Enterprise & Astra DB

For organizations seeking enterprise features and managed services, Nextbrick provides deep expertise with DataStax Enterprise (DSE) and DataStax Astra DB. We deploy and configure DSE's integrated search (Solr), analytics (Spark), and graph capabilities that extend Cassandra's core functionality for complex use cases like recommendation engines, knowledge graphs, and full-text search. Our consultants help teams evaluate and adopt Astra DB's serverless Cassandra offering, configuring multi-region deployments, vector search for AI applications, and Stargate APIs for REST, GraphQL, and document-style access.

We handle migrations between open-source Cassandra and DataStax offerings, ensuring compatibility, performance parity, and minimal disruption to running applications.

Time-Series & IoT Workloads

Cassandra excels at high-write-throughput workloads, making it a natural fit for time-series data from IoT sensors, application metrics, log events, and financial transactions. Nextbrick designs time-series schemas with time-bucketed partitions that prevent unbounded partition growth while supporting efficient range queries over temporal data. We implement TTL-based data expiration and compaction strategy tuning—selecting between SizeTiered, Leveled, and TimeWindow compaction—to maintain read performance and manage storage costs as data accumulates.

Our engineers build ingestion pipelines that feed Cassandra from Kafka, Spark Streaming, and custom producers, handling backpressure, batching, and retry logic to sustain write rates of hundreds of thousands of operations per second per node.

Operations, Monitoring & Repair

Running Cassandra in production requires specialized operational expertise. Nextbrick's operations team implements comprehensive monitoring using Prometheus, Grafana, and Cassandra's JMX metrics to track read/write latencies, compaction throughput, heap utilization, and gossip health across every node in your cluster. We configure alerting for critical conditions like dropped mutations, blocked compactions, and hinted handoff backlogs that indicate emerging problems.

We automate routine maintenance tasks—repairs, compactions, cleanup, and rolling restarts—using Cassandra Reaper and custom automation playbooks. Our engineers design backup strategies with Medusa and implement point-in-time restore procedures that satisfy your disaster recovery requirements across multi-datacenter deployments.

Performance Tuning & Scaling

Nextbrick's performance engineers conduct deep-dive assessments of your Cassandra clusters, analyzing trace data, compaction statistics, bloom filter effectiveness, and GC behavior to pinpoint bottlenecks. We tune JVM settings, memtable configurations, and read/write thread pools to match your hardware profile and workload characteristics. For clusters experiencing growing pains, we design expansion plans that add capacity seamlessly using Cassandra's native token-aware scaling—no downtime, no data migration headaches.

Our capacity planning models project growth based on your data ingest rates, retention policies, and query volumes, ensuring you scale proactively rather than reactively.
