Change subject: IMPALA-11986: (part 1) Optimize partition key scans for Iceberg 
tables
......................................................................


Patch Set 1: Code-Review+2

LGTM.

I just wonder what happens in the following case:
Originally, the table was not suited for partition key scan optimization. Then 
the user changed the partition spec and compacted the table so that now it 
could use the optimization. If the old snapshots referencing the old files are 
expired, would the metadata still contain the old partition spec, blocking the 
optimization?
Maybe it is worth testing to see the limitations. But nice patch, anyway, 
thanks!
