Column families are fundamental to understanding how BigTable organizes data, which affects performance and cost.
The candidate should explain that column families group related data together, and that each column family can have different storage and performance settings. This shows an understanding of data optimization and schema design in BigTable.
Row key design is critical as it impacts the efficiency of data retrieval and scalability of the database.
Look for an explanation of how row keys affect data distribution and access patterns. A good response would include examples such as designing row keys to avoid hotspots by ensuring that data accesses are spread evenly across the table's nodes.
Knowledge of basic data operations and the tools used for interacting with BigTable is necessary for effective data management.
The candidate should mention operations such as creating, reading, updating, and deleting data. Listen for mentions of using the Google Cloud Console, the cbt command-line tool, or BigTable client libraries, which indicates a practical understanding of how to interact with BigTable.
