What changed
DELETEactions into Spark DataEvolutionMERGE INTO, including mixed update/delete sequencing and Spark 4.0 parity.Why
DataEvolution tables currently handle merge updates/inserts, but matched deletes need to physically rewrite the affected row-id ranges so normal files and corresponding blob files stay aligned.
