BigTable Assessment Test

A BigTable Assessment Test evaluates candidates for their proficiency in Google Cloud Bigtable, a fully managed, scalable NoSQL database service for large analytical and operational workloads. Bigtable is designed to handle massive volumes of data with low latency and high throughput, making it suitable for various use cases, including IoT, time series data, and analytics.

A BigTable Assessment Test evaluates candidates for:

1. Bigtable Basics: Understanding of Bigtable concepts, including data model, tables, rows, columns, and cells, and how Bigtable differs from traditional relational databases.
2. Schema Design: Proficiency in designing efficient Bigtable schemas tailored to specific use cases, considering factors such as access patterns, data locality, and scalability.
3. Data Modeling: Ability to model data for optimal performance and storage efficiency in Bigtable, including denormalization, column families, and data partitioning strategies.
4. Data Operations: Competency in performing CRUD (Create, Read, Update, Delete) operations in Bigtable, using APIs and client libraries such as HBase, Dataflow, or the Bigtable REST API.
5. Data Import and Export: Knowledge of techniques for importing data into Bigtable from external sources (e.g., Cloud Storage, Hadoop) and exporting data from Bigtable to other destinations.
6. Querying and Filtering: Understanding of querying and filtering data in Bigtable using key-based lookups, range scans, filters, and secondary indexes.
7. Performance Optimization: Familiarity with optimizing Bigtable performance, including tuning for low latency, high throughput, and efficient resource utilization.
8. Data Consistency and Durability: Understanding of Bigtable's consistency model and durability guarantees, including replication, consistency levels, and data durability configurations.
9. Access Control and Security: Knowledge of configuring access control policies, authentication mechanisms, and encryption for securing data in Bigtable.
10. Monitoring and Maintenance: Proficiency in monitoring Bigtable performance, health, and resource usage using monitoring tools like Stackdriver and performing routine maintenance tasks like backups and schema updates.

Overall, our BigTable Assessment Test measures candidates' knowledge, skills, and hands-on experience in designing, managing, and optimizing Google Cloud Bigtable deployments, providing valuable insights into their capabilities in working with large-scale NoSQL databases for big data applications.
