NET. The client supports an annotation-driven 5 I am trying to map by custom defined class to a DynamoDB table using DynamoDB Mapper annotations: Answer Yes, DynamoDB supports nested objects in a Map data type. Hardest part is that I can't find any information about this with Google. These data types can be nested within each other, to represent complex data structures up to 32 levels deep. Overview The DynamoDB Enhanced Client API library allows us to integrate DynamoDB into Java and Kotlin application code. I've got an application that stores some data in DynamoDB using Jackson to marshall my complex object into a JSON. table is a map, where each entry corresponds to a specific There are Object Mappers for JPA support for NoSQL databases like Mongo, Couch in Hibernate OGM, Spring Data. This Mistake: Choosing to store complex JSON objects as strings, which could limit querying capabilities. g. NET object persistence model. But, I could not able to find any reliable and actively I have a complex object Test in the entity class Item. Map your client-side classes to the Amazon DynamoDB tables using the object persistence model of the AWS SDK for . Solution: Use List/Map types for complex data that requires frequent access or I have tried to map it to Java object using many ways, mostly by DynamoDBTypeConverter.
