Comparison Table – Scan vs. Query
| Scan | Query | |
|---|---|---|
| Primary Use Case | Retrieval of all items in a table or a subset of items based on filtering criteria | Retrieval of a specific item or a subset of items based on partition key and/or sort key values |
| Performance | Slower, as it accesses all items in a table | Faster, as it accesses only specific items |
| Usage | When the required data is scattered across the table or you need to retrieve a large amount of data | When you need to access specific items quickly |

- What is DynamoDB?
- What is Boto3?
- What is a complete scan in DynamoDB?
- Why is Boto3 useful for interacting with DynamoDB?
- What are some best practices for scanning a DynamoDB table with Boto3?
DynamoDB is a fully managed NoSQL database service provided by Amazon Web Services (AWS). It is designed to provide fast and predictable performance with seamless scalability.
Boto3 is the Amazon Web Services (AWS) Software Development Kit (SDK) for Python, which allows Python developers to write software that makes use of services like Amazon S3 and Amazon EC2.
A complete scan in DynamoDB refers to reading all items from a table, regardless of whether or not they meet a specific query criteria. This is a resource-intensive operation and should be used judiciously.
Boto3 provides a simple and intuitive interface to interact with DynamoDB. It handles low-level details such as connection management and request marshalling, allowing developers to focus on writing high-level application logic. Additionally, Boto3 provides a rich set of features for interacting with DynamoDB, including support for batch operations and complex queries.
- Use pagination to limit the number of results returned in each API call and prevent timeouts.
- Optimize read capacity by minimizing the amount of data returned and using projection expressions to only return the attributes you need.
- Consider using parallel scans to improve performance on large tables.
- Ensure your code can handle throttling and retry failed requests.
