Basic Concepts

  1. What is Azure Cosmos DB?

    Answer: Azure Cosmos DB is a globally distributed, multi-model database service designed to provide high availability, scalability, and low latency. It supports multiple data models including document, key-value, graph, and column-family data models. It offers automatic indexing, comprehensive SLAs, and multi-region replication.

  2. What are the different data models supported by Cosmos DB?

    Answer: Azure Cosmos DB supports the following data models:

    • Document Model: Uses JSON documents (e.g., with the SQL API).
    • Key-Value Model: Stores data as key-value pairs (e.g., with the Table API).
    • Graph Model: Represents data as nodes and edges (e.g., with the Gremlin API).
    • Column-Family Model: Stores data in a column-family format (e.g., with the Cassandra API).
  3. What is the partitioning strategy in Azure Cosmos DB?

    Answer: Azure Cosmos DB uses partitioning to scale out databases. It divides data into logical partitions, each with its own set of resources. The partition key is used to distribute data across these partitions. Proper selection of the partition key is crucial for balanced performance and scalability.

  4. Explain the concept of “Consistency” in Cosmos DB.

    Answer: Consistency in Cosmos DB refers to the level of guarantee provided about the order and visibility of data updates. Cosmos DB offers five consistency models:

    • Strong: Guarantees the highest level of consistency with the latest data always visible.
    • Bounded Staleness: Provides a guarantee that reads will be at most a specified number of versions or time lag behind writes.
    • Session: Guarantees consistency within a single session, ensuring that a client sees its own writes.
    • Eventual: Guarantees that all replicas will eventually converge to the same value, but without immediate consistency.
    • Consistent Prefix: Guarantees that reads will see the operations in the order they were issued.
  5. What is the role of the “Request Units” (RUs) in Cosmos DB?

    Answer: Request Units (RUs) are a currency for measuring the performance of Cosmos DB operations. They represent the cost of operations like reads, writes, and queries. Each operation consumes a certain number of RUs, and you are billed based on the RUs consumed by your database operations.
