Best practices for deploying Cassandra at scale include the following:

When designing a data model, it is important to consider the data access patterns and query requirements, and avoid using overly normalized or complex relational models.
Cluster size: In large-scale deployments, it is important to consider the size of the cluster, including settings for parameters such as number of nodes, replicas, and shards, in order to ensure the performance and availability of the system.
Strategy for data distribution: Choose appropriate strategies for distributing data, including selecting partition keys and data sharding strategies, to ensure that data is evenly distributed across the cluster, thus avoiding hotspots and performance bottlenecks.
Hardware selection: Choose hardware that is suitable for deploying Cassandra, including high-performance storage devices, network devices, and computing resources, to fully leverage Cassandra’s performance advantages.
Monitoring and optimization: Real-time monitoring of cluster performance and status to promptly identify and address potential issues, conducting system optimizations to enhance system performance and availability.
Establishing a comprehensive data backup and recovery strategy is essential to ensure the security and reliability of data, especially in the event of emergencies or data loss situations.
Security assurance: Enhance the security controls of the system, including access permissions, data encryption, firewalls, etc., to protect the system from potential security threats.

In conclusion, for large-scale deployments, Cassandra needs to consider aspects such as data modeling, cluster size, data distribution strategy, hardware selection, monitoring and optimization, data backup and recovery, and security measures to ensure the performance, availability, and security of the system.
