Annotations Sometimes people describe annotations as tags but that is a limited definition. There are many different kinds of annotations our client applications want to generate. To store data in frames clients must also store frames per second. This allows our clients to create an “is-a-type-of” relationship between schemas.

Dynatrace supports the newly released AWS Lambda Response Streaming

This enhancement allows AWS users to stream response payloads back to clients. Now, customers can use streamed responses to build more responsive applications by sending partial responses to clients as the response becomes available. Lambda Response Streaming enables AWS Lambda functions to stream response payloads back to clients.

Best practice: Filter results with management zones or tag filters. If your environment is organized with tags, you can add tag filters to further reduce the result set and to speed up the query. We often see API client scripts that query all topology information on a per-minute basis.
