fix(memory-storage): Apply skip_empty after pagination in MemoryDatasetClient.get_data#1937
Merged

Conversation
The skip_empty filter was applied before the offset/limit slice, so the same query returned different items than FileSystemDatasetClient.get_data and even MemoryDatasetClient.iterate_items. Paginate first and filter the sliced page to keep all storage clients consistent.

MemoryDatasetClient.get_dataapplied theskip_emptyfilter before theoffset/limitslice, whileFileSystemDatasetClient.get_dataandMemoryDatasetClient.iterate_itemsboth paginate first and then drop empty items. As a result,get_data(skip_empty=True, offset=N, limit=M)returned a different set of items depending on the storage backend, and disagreed withiterate_itemson the same memory client.This change reorders the operations in
MemoryDatasetClient.get_datato apply thedescreversal, then theoffset/limitslice, and only then filter out empty items — matching the other implementations. The returnedcount/total/offsetpagination math is now also internally consistent whenskip_empty=True.
