Hello Iceberg Dev, The Iceberg specification for matching delete files with data files during scan planning states :
"The data file’s partition (both spec and partition values) is equal to the delete file’s partition" Equality of partition specs appears slightly ambiguous (apologies if I missed this). I can imagine two different definitions: 1. Equality of partition spec identifier. 2. Equality of each element in the partition spec tuple (which raises the further question of which elements of a partition transform are considered for equality). This is distinct from option one only when identical tuples are allowed in the partition spec map with two different identifiers. I would assume the definition should be based on the partition spec identifier but wanted to clarify. Thanks, Micah
