@aljoscha yes, I agree.

The "query" you mean `JobAccumulatorsHandler` or `RestClusterClient`
behavior?
In `JobAccumulatorsHandler#handleRequest` method, we could query the
accumulator's string and serialized representations, and boxed in
`JobAccumulatorsInfo` object.
1. let `getAccumulators` return accumulator's string representations and
`getSerializedAccumulators` method return accumulator's serialized
representations.
2. let `getAccumulators` return both representations?
Which one is your idea?
