Review comment:
Can we mark these fields as private? Any particular reason they are
package private?

Review comment:
nit, no need to use fully qualified List here. also for String. Same for
the earlier builder class as well. Please make these fields private.

Review comment:
From a user perspective, I think it would be more user friendly to have
builder class for the whole request objects (eg. GetPartitionsRequestBuilder
which gives ability to create a projection and filter spec)

Review comment:
Not related to your change, but looks like that TODO should be removed
since we have the filterspec implemented.
