For example, if some of the keys are: "abcd_aaa" "abcd_bbb" "abcd_ccc" I want to query where a key contains … One of these is begins_with. In this post, we are going to look at some of the components and terms used in DynamoDB. DynamoDB is a high-performance NoSQL database service offered by AWS as a part of its AWS Cloud Stack. In this example, you’ll see that we keep the simple syntax for creating our params. You can copy or download my sample data and save it locally somewhere as data.json. The DynamoDB Book contains 5 example walkthroughs, as well as strategies for handling relationships, filtering, sorting, and more. To perform these advanced queries, we need some data to work with.
