New test cases after introducing new features via data store

[hunterhector]

Is your feature request related to a problem? Please describe.
Datastore features are tested independently, and the current set of data pack test do not cover all new features. We would try to cover these new features through the data pack interface

Describe the solution you'd like
The test cases are:

• Serialization/deserialization check

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

Additional context

• This is part of the data efficiency project
• This PR should be made to the master branch.
• After the data tuple class is finished, we may switch to a new branch for integration.
