Cassandra Distribution څه شی دی

Apache Cassandra is a distributed, open-source NoSQL database designed for handling massive amounts of structured data across multiple commodity servers with high availability and fault tolerance. It excels at time-series data, event logging, and applications requiring multi-datacenter replication. Job relevance: Database engineers, DevOps professionals, and backend developers need Cassandra expertise for large-scale systems. Premium salaries for skilled practitioners in tech companies.

❓ ډېرې پوښتل شوې پوښتنې

When should I use Cassandra over relational databases?
High throughput, massive scale (millions of requests/sec), multi-datacenter replication needed.
What's the learning curve?
Steep; distributed systems concepts and NoSQL mindset required; 3-6 months for proficiency.
How different is CQL from SQL?
Similar syntax; semantic differences (no joins, denormalization required, eventual consistency).
What's the operational overhead?
Significant; cluster management, monitoring, and tuning require expertise.
Can Cassandra handle transaction?
No ACID transactions; lightweight transactions available but limited.
How do I design for Cassandra?
Query-driven design; model around access patterns, not relationships.
