They don't happen a lot, but they do happen. DynamoDB is AWS’s managed NoSQL solution, and commonly the first choice for providing database services when working with AWS Lambda.. With DynamoDB, you can create database tables that can store and retrieve any amount of data, and serve any level of request traffic. The AWS SDKs take care of propagating errors to your application so that you can take appropriate action. The base backoff time (in milliseconds) between each describeStream attempt (for consuming from DynamoDB streams). DynamoDB was designed from the beginning to be extremely scalable. Turns out there's an under-documented feature you can use to config the number of retries (as mojimi hints), which exponentially increase the backoff time. When designing your application, keep in mind that DynamoDB does not return items in any particular order. ; Returns. ademidun / python-dynamo-utils.py. By default, BatchGetItem performs eventually consistent reads on every table in the request. Seejärel kasutab ta üksuse räsivõtit, et määrata, milline partitsioon üksust salvestada.
