> Apache Datasketches allows to create ReqSketch or t-digest histogram
sketches. Other histogram sketch algorithms might be added in the future. I
mean that it would be nice to be able to store a t-digest sketch in Iceberg,
instead of a KLL sketch. If we follow that approach, it should be possible to
define the type per column, so that, e.g., column `a` could have a KLL sketch,
and column `b` a t-digest sketch.
Is this what you mean:
sketch {
type: KLL | TDIGEST | REQ
payload: bytes
}
