Merged
Conversation
Add compaction.Analyze(ctx, tbl, cfg) as a read-only entry point that scans the table via PlanFiles and produces a compaction Plan without modifying anything. Useful for dry-run analysis, CLI tooling, and deciding whether compaction is worthwhile before executing. E2e tests with real Parquet files: - Small files detected as compaction candidates - Optimal files skipped when below MinInputFiles - Empty table produces empty plan - Invalid config returns error Part of apache#832 (table compaction).
