Absolutely. We won't address that in the initial release of 2.0, but there will be ways to get it done. The eventual solution will probably revolve around using the tasks system to downsample into buckets of different retention. Then using a function in Flux at query time to look at the metadata of buckets in the query and the time range and selecting the precision based on that. We should be able to show examples of how to do this in Flux later this year.
