角色	必要性	描述
Data Engineer	必要	Writes basic CQL queries to read and insert data into Cassandra tables. Understands partition keys and clustering columns in existing schemas. Follows data modeling guidelines established by the team.
Database Engineer / DBA		Performs basic Cassandra cluster health checks using nodetool. Understands replication factors and consistency levels at a conceptual level. Executes routine maintenance tasks like repairs and compactions under guidance.

角色	必要性	描述
Data Engineer	必要	Designs Cassandra data models optimized for query-driven access patterns. Implements efficient batch operations and manages TTL-based data lifecycle. Tunes read/write consistency levels to balance latency and durability.
Database Engineer / DBA		Designs table schemas balancing partition size and read performance in Cassandra. Configures compaction strategies and manages tombstone accumulation. Monitors cluster metrics and resolves hotspot and latency issues.

角色	必要性	描述
Data Engineer	必要	Architects multi-datacenter Cassandra deployments for real-time data pipelines. Optimizes cluster topology, compaction strategies, and partition distribution for petabyte-scale workloads. Designs migration strategies between schema versions.
Database Engineer / DBA	必要	Architects Cassandra clusters for high-availability across multiple datacenters. Designs replication and sharding strategies for petabyte-scale systems. Leads capacity planning, disaster recovery procedures, and performance tuning at scale.

角色	必要性	描述
Data Engineer	必要	Defines product-level data strategy. Establishes Apache Cassandra standards. Conducts data schema and scaling strategy reviews.
Database Engineer / DBA	必要	Defines data strategy at the product level. Establishes Apache Cassandra standards. Conducts data schema and scaling strategy reviews.

角色	必要性	描述
Data Engineer	必要	Designs NoSQL strategy for data platform: Cassandra for high-write ingestion, ScyllaDB for low-latency lookups. Defines data modeling best practices for wide-column stores and Spark integration for batch analytics.
Database Engineer / DBA	必要	Defines Cassandra strategy for the data platform: partition key design for DBA metrics, consistency levels for different use cases, multi-DC replication. Evaluates Cassandra vs ScyllaDB for DB monitoring time-series workloads.
