Hi
I'm executing simple merge, however it always stucks at "MERGE operation - scanning files for matches". Both delta tables are not big - source has about 100MiB in 1 file and target has 1,5GiB, 7 files, so it should be quite fast operation, however it stuck infinitly on this:
Both tables are external type and located on ADLS gen2.
On the other hand using replace table using select * processes without problems.
