What it checks

Iceberg

• Snapshot count: too many slows query planning
• Small files: impacts read performance
• Schema drift: too many schema versions
• Partition spec: missing means full scans

Delta

• Commit count: too many without checkpoint slows reads
• Small files
• Schema changes
• Remove/add file ratio

Hudi

• Inflight commits: stuck or failed writes
• Commit count
• Operation types (insert vs upsert)
• Write sizes: too small means unbatched writes

Requirements

Python 3.8+
