Required Expertise
What You'll Work On
Database Migration
Migrate your data estate to Apache Cassandra with zero data loss. Consultants assess schema compatibility, convert stored procedures and data types between platforms, execute test migrations with row-count and checksum validation, and design a cutover plan with replication-based sync to minimize downtime during the final switchover.
Performance Tuning & Query Optimization
Eliminate slow queries and resource bottlenecks in your Apache Cassandra databases. Consultants analyze execution plans and wait statistics, redesign problematic indexes and table structures, implement query store or equivalent profiling for ongoing regression detection, and tune memory, I/O, and concurrency settings to match your workload patterns.
High Availability & Disaster Recovery
Architect highly available Apache Cassandra database topologies. Consultants design Always On, replication, or clustering configurations appropriate to your RPO and RTO targets, implement automated failover with connection retry logic at the application layer, and conduct regular DR drills that prove recoverability before you actually need it.
Schema Design & Data Modeling
Design Apache Cassandra database schemas that balance performance, maintainability, and future growth. Consultants create normalized or denormalized models aligned with your access patterns, define partitioning strategies for large tables, implement constraint-based integrity rules, and document data dictionaries that keep development teams aligned as the schema evolves.
