From 27468ebfa9fd12a3c88f2a1522a7f3286a3e3b68 Mon Sep 17 00:00:00 2001 From: houseme Date: Sun, 28 Jun 2026 07:14:07 +0800 Subject: [PATCH] feat(get): consolidate GET performance optimization (#3972) * feat(get): consolidate GET performance optimization Consolidated implementation of all GET performance optimizations into a single, well-organized commit replacing the previous patch-on-patch approach. ## Changes ### Configuration (set_disk/mod.rs) - Consolidated all GET optimization flags into a single organized section - Enabled by default: codec streaming, metadata early-stop, page cache reclaim - Added codec streaming multipart flag (default: disabled) - Added version-aware early-stop flag (default: disabled) - Added adaptive duplex buffer sizing based on object size - All flags use OnceLock caching with rollout percentage support ### Metadata Early-Stop (set_disk/read.rs) - Delete marker early-stop when quorum agrees - Version-aware early-stop for versioned GET requests - MetadataQuorumAccumulator enhanced with: - delete_marker_votes tracking - requested_version_id and matching_version_votes tracking - version_early_stop_decision() method - 6 new tests for version early-stop scenarios ### Codec Streaming (erasure/coding/decode_reader.rs) - DualInFlight (2-stripe lookahead) enabled by default ### Decode Pipeline (erasure/coding/decode.rs) - Stripe prefetch count configuration - Bitrot-decode overlap configuration ### Disk Layer (disk/local.rs) - O_DIRECT read configuration constants (preparation) ### Metrics (io-metrics/lib.rs) - BytesPool acquisition/return metrics - Metadata phase duration with early-stop label - Total duration with reader_path label ### Diagnostics (diagnostics/) - Early-stop reason constants - Pool tier/outcome label constants ### Observability (.docker/observability/) - 3 Grafana dashboards for GET optimization monitoring - Prometheus alert rules (6 alerts: 3 critical, 3 warning) - Updated README.md and README_ZH.md with usage docs ### Config (config/src/constants/runtime.rs) - Page cache reclaim read enabled by default ## Environment Variables | Variable | Default | Description | |----------|---------|-------------| | RUSTFS_GET_CODEC_STREAMING_ENABLE | true | Codec streaming base flag | | RUSTFS_GET_CODEC_STREAMING_ROLLOUT_PCT | 100 | Codec streaming rollout % | | RUSTFS_GET_CODEC_STREAMING_MULTIPART_ENABLE | false | Multipart codec streaming | | RUSTFS_GET_METADATA_EARLY_STOP_ENABLE | true | Early-stop base flag | | RUSTFS_GET_METADATA_EARLY_STOP_ROLLOUT_PCT | 100 | Early-stop rollout % | | RUSTFS_GET_METADATA_VERSION_EARLY_STOP_ENABLE | false | Version-aware early-stop | | RUSTFS_OBJECT_FILE_CACHE_RECLAIM_READ_ENABLE | true | Page cache reclaim | | RUSTFS_OBJECT_DIRECT_IO_READ_ENABLE | false | O_DIRECT (preparation) | | RUSTFS_GET_DECODE_STRIPE_PREFETCH_COUNT | 1 | Stripe prefetch | | RUSTFS_GET_BITROT_DECODE_OVERLAP_ENABLE | false | Bitrot-decode overlap | | RUSTFS_GET_CODEC_STREAMING_MAX_INFLIGHT | 2 | DualInFlight stripes | ## Rollback All optimizations can be disabled via environment variables: RUSTFS_GET_CODEC_STREAMING_ENABLE=false RUSTFS_GET_METADATA_EARLY_STOP_ENABLE=false RUSTFS_OBJECT_FILE_CACHE_RECLAIM_READ_ENABLE=false Co-Authored-By: heihutu * test(get): add stress test scripts for GET optimization validation -
