The method through which AWS products achieve high availability, which involves replicating data across multiple servers in Amazon’s data centers. When data is written or updated and
Success is returned, all copies of the data are updated. However, it takes time for the data to propagate to all storage locations. The data will eventually be consistent, but an immediate read might not show the change. Consistency is usually reached within seconds.
See also data consistency.

A process that is used to integrate data from multiple sources. Data is collected from sources (extract), converted to an appropriate format (transform), and written to a target data store (load) for purposes of analysis and querying.
ETL tools combine these three functions to consolidate and move data from one environment to another. AWS Glue is a fully managed ETL service for discovering and organizing data, transforming it, and making it available for search and analytics.

The process of responding to an API request by returning a large list of records in small separate parts. Pagination can occur in the following situations:
- The client sets the maximum number of returned records to a value below the total number of records.
- The service has a default maximum number of returned records that is lower than the total number of records.
When an API response is paginated, the service sends a subset of the large list of records and a pagination token that indicates that more records are available. The client includes this pagination token in a subsequent API request, and the service responds with the next subset of records. This continues until the service responds with a subset of records and no pagination token, indicating that all records have been sent.pagination token
A marker that indicates that an API response contains a subset of a larger list of records. The client can return this marker in a subsequent API request to retrieve the next subset of records until the service responds with a subset of records and no pagination token, indicating that all records have been sent.

Amazon API Gateway uses throttling to limit the steady-state request rates for a single account. Amazon SES uses throttling to reject attempts to send email that exceeds the sending limits.time series data

The process of confirming that you own an email address or a domain so that you can send email from or to it.VERP
Variable Envelope Return Path. A way in which email sending applications can match bounced email with the undeliverable address that caused the bounce by using a different return path for each recipient. VERP is typically used for mailing lists. With VERP, the recipient’s email address is embedded in the address of the return path, which is where bounced email is returned. This makes it possible to automate the processing of bounced email without having to open the bounce messages, which may vary in content.versioning
Every object in Amazon S3 has a key and a version ID. Objects with the same key, but different version IDs can be stored in the same bucket. Versioning is enabled at the bucket layer using PUT Bucket versioning.VGW
