rraulinio opened a new pull request, #1154:
URL: https://github.com/apache/iceberg-go/pull/1154

   Fixes #1153.
   
   Overwrite commits read existing manifest entries with deleted entries 
filtered out. If no live entries remain, carrying that manifest forward keeps 
stale deletion history reachable in the current snapshot and causes repeated 
replace operations to grow the manifest list.
   
   This change skips existing overwrite manifests that have no live entries 
after `discardDeleted=true` filtering. It does not rely on manifest-level count 
metadata, so zero-count inherited manifests that still contain live entries are 
still preserved.
   
   A regression test covers repeated `ReplaceDataFilesWithDataFiles` calls and 
verifies the current snapshot keeps a bounded manifest list instead of 
accumulating old delete-only manifests.
