Is there any way to implement dynamic key value type data indexing in AWS dynamodb? e.g. Some documents may have key-values as "Key1"-> "value1" other may have "key2"-> "value2" and so on.
I would like to search on these key values efficiently using indexing. In short I am looking for Wildcard indexing feature like CosmosDb where it indexes every property.
If not with AWS DocumentDb, any AWS database recommendations for this type of problem statement?
