There was a problem hiding this comment.
Why is this a checked supplier? Under what condition can it ever throw IOException?
There was a problem hiding this comment.
LGTM, except I don't think we need IOException there. I suspect we can convert CheckedSupplier to Supplier in case of tsid as well. I think it is CheckedSupplier for purely historical reasons.
Yeah, I also think Supplier is better, I have converted CheckedSupplier to Supplier for timestamp and tsid.

As LeafWalker already get the timestamp from doc values, It can add a timestampProvider in the AggregationExecutionContext.
It's useful in the time serise downsampling sense. downsampling collect can get the timestamp from the AggregationExecutionContext.
And It will have other more use case.
