From 0f83d74c52e9596c691ef5ee5994c8d3be179560 Mon Sep 17 00:00:00 2001 From: Chris Lu Date: Sat, 31 Jan 2026 15:27:06 -0800 Subject: [PATCH] feat(s3tables): implement table maintenance operations and admin UI integration Changes: - Implement actual maintenance operations with progress reporting: - Compaction: analyze data files and plan compaction groups - Snapshot expiration: identify and expire old snapshots - Orphan cleanup: find unreferenced files for deletion - Manifest rewrite: optimize manifest file structure - Add Iceberg operations support (iceberg_ops.go): - IcebergTableMetadata parsing - Snapshot analysis and expiration detection - File reference tracking - Small file detection for compaction - Integrate with admin UI: - Add table_maintenance to maintenance_handlers.go - Add persistence methods in config_persistence.go - Support configuration save/load for table maintenance - Add comprehensive integration tests: - Full workflow tests for each job type - Scheduling tests with concurrency limits - Worker capability and load tests - Config persistence round-trip tests - Iceberg operations tests Note: Full compaction/manifest rewrite requires parquet/avro library integration which is deferred. --- weed/admin/dash/config_persistence.go | 71 ++- weed/admin/handlers/maintenance_handlers.go | 10 + .../tasks/table_maintenance/iceberg_ops.go | 302 +++++++++++
