Cassandra Admin (L3)

Cassandra Admin (L3) with Datastax with all admin activities like backup, restore, repair, data replication, and compaction strategies.

Performance Tuning and Troubleshooting. Advantage with Kubernetes knowledge

Administration Operations Install, configure, manage, and maintain large-scale Cassandra and Redis database clusters in production environments (on-premise and/or cloud platforms like AWS, Azure).
Performance Tuning Optimization Monitor database performance, identify bottlenecks, and implement optimizations for queries, data models, JVM heap settings (for Cassandra), memory usage, and eviction policies (for Redis).
High Availability Disaster Recovery Develop, implement, and test backup, recovery, and disaster recovery strategies (e.g., nodetool snapshots, RDBAOF persistence) to ensure data durability and minimal downtime.
Troubleshooting Root Cause Analysis Serve as an L3L4 escalation point for complex production incidents, perform root cause analysis (RCA), and implement permanent fixes.
Architecture Design Collaborate with architects and developers on optimal data modeling, schema design, capacity planning, and the implementation of appropriate replication strategies and consistency levels.
Security Compliance Implement and enforce robust security measures, including authentication (LDAP, Kerberos), authorization (RBAC, ACLs), and encryption (TLSSSL), ensuring compliance with industry standards (e.g., GDPR, HIPAA).Monitoring Alerting Set up and manage monitoring and alerting tools (e.g., Prometheus, Grafana, OpsCenter) to proactively track database health and performance metrics.
Automation Automate routine administrative tasks, deployments, and scaling activities using scripting languages (Bash, Python) and Infrastructure as Code (IaC) tools (Terraform, Ansible).
Collaboration Documentation Work effectively with DevOps, SRE, application, and infrastructure teams, and maintain detailed documentation (runbooks, SOPs).
