| Another Heuristic can be applied for time buckets if you use a `date_histogram` to | ||
| group by time buckets. Change detection will detect which time buckets have changed | ||

Another improvement idea:
It would be good to explain a checkpointing best practice: using ingest timestamps (requires 7.11) instead of timestamps that are coming from outside. However I am not sure if this belongs here or in the put transform documentation (or both)

I created some visuals about change point detection, e.g. in #63315
This is a very technical one, but maybe we can take the ideas from it to create a better visual for this place.

Draft
With #54068 change detection optimized uses cases with date histograms. This optimization isn't reflected in the docs yet. I think it also makes sense to give an example.
