houseme 0c4c1caef8 perf(ecstore): add Vec<u8> buffer pool for EC operations (#6538)
* feat(mimalloc): add arena diagnostics and configuration

Based on mimalloc maintainer feedback (microsoft/mimalloc#1372),
add diagnostics to check mimalloc arena configuration at runtime.

Changes:
- Add rustfs-mimalloc-sys to workspace dependencies
- Add log_mimalloc_diagnostics() function to check:
  - arena_max_object_size
  - pagemap_commit status
  - mimalloc version
- Add memory_observability module with mimalloc diagnostics

This helps diagnose why allocations might be going outside arenas,
which is the suspected root cause of futex contention.

* perf(ecstore): add Vec<u8> buffer pool for EC operations

Add a general-purpose buffer pool to reduce Vec<u8> allocations
in hot paths like EC encoding/decoding.

Changes:
- Add BufferPool struct in crates/ecstore/src/erasure/codec/buffer_pool.rs
- Thread-safe pool with capacity-based bucketing (power-of-two)
- Global EC_BUFFER_POOL instance with 16 buffers per bucket
- Add buffer_pool module to codec/mod.rs

Expected impact:
- Reduce heap allocations in EC encode/decode paths
- Avoid memzero overhead (proven 4.8% CPU saving in ShardBufferPool)
- Reduce mimalloc lock contention

Note: Main bottleneck remains mimalloc internal synchronization
(futex 98.64% time). Buffer pool provides modest improvement (+2-5%).

* style: apply cargo fmt to buffer pool and related files

* fix(ecstore): add #[allow(dead_code)] to buffer pool

The BufferPool infrastructure is ready but not yet integrated
into the EC hot paths. Add #[allow(dead_code)] with clear
documentation about integration status.

* perf(ecstore): integrate BufferPool into bitrot verify path

Replace vec![0; shard_size] with get_ec_buffer() in the bitrot
verification hot path to reduce heap allocations and avoid memzero.

* refactor(ecstore): clean up buffer pool code

- Remove unnecessary #[allow(dead_code)] attributes
- Update module documentation to reflect current integration status
- Simplify code structure

* perf(runtime): cap default worker threads at 16

Testing showed 16 worker threads outperforms 32+ for 1KiB PUT
workloads due to reduced mimalloc lock contention.

A/B test results (testing 4-node cluster, c=64):
- worker_threads=32: 740 obj/s (baseline)
- worker_threads=16: 785 obj/s (+6.1%)

The default was detect_cores() which returned 32 on our testing
nodes. Cap at 16 for optimal small-object performance.

* fix(ecstore): remove unused BufferPool::new() function

The new() function was never used since EC_BUFFER_POOL
initializes directly with with_limits(16).

* fix(ecstore): update buffer_pool tests to use with_limits

Replace BufferPool::new() with BufferPool::with_limits(16) in tests
since new() was removed in favor of with_limits().

RustFS Docker Infrastructure

This directory contains the complete Docker infrastructure for building, deploying, and monitoring RustFS. It provides ready-to-use configurations for development, testing, and production-grade observability.

📂 Directory Structure

Directory Description Status
observability/ [RECOMMENDED] Full-stack observability (Prometheus, Grafana, Tempo, Loki). Production-Ready
compose/ Specialized setups (e.g., 4-node distributed cluster testing). ⚠️ Testing Only
mqtt/ EMQX Broker configuration for MQTT integration testing. 🧪 Development
openobserve-otel/ Alternative lightweight observability stack using OpenObserve. 🔄 Alternative

📄 Root Directory Files

The following files in the project root are essential for Docker operations:

Build Scripts & Dockerfiles

File Description Usage
docker-buildx.sh Multi-Arch Build Script
Automates building and pushing Docker images for amd64 and arm64. Supports release and dev channels.
./docker-buildx.sh --push
Dockerfile Production Image (Alpine)
Lightweight image using musl libc. Downloads pre-built binaries from GitHub Releases.
docker build -t rustfs:latest .
Dockerfile.glibc Production Image (Ubuntu)
Standard image using glibc. Useful if you need specific dynamic libraries.
docker build -f Dockerfile.glibc .
Dockerfile.source Development Image
Builds RustFS from source code. Includes build tools. Ideal for local development and CI.
docker build -f Dockerfile.source .

Docker Compose Configurations

File Description Usage
docker-compose.yml Main Development Setup
Comprehensive setup with profiles for development, observability, and proxying.
docker compose up -d
docker compose --profile observability up -d
docker-compose-simple.yml Quick Start Setup
Minimal configuration running a single RustFS instance with 4 volumes. Perfect for first-time users.
docker compose -f docker-compose-simple.yml up -d

Located in: .docker/observability/

We provide a comprehensive, industry-standard observability stack designed for deep insights into RustFS performance. This is the recommended setup for both development and production monitoring.

Components

  • Metrics: Prometheus (Collection) + Grafana (Visualization)
  • Traces: Tempo (Storage) + Jaeger (UI)
  • Logs: Loki
  • Ingestion: OpenTelemetry Collector

Key Features

  • Full Persistence: All metrics, logs, and traces are saved to Docker volumes, ensuring no data loss on restarts.
  • Correlation: Seamlessly jump between Logs, Traces, and Metrics in Grafana.
  • High Performance: Optimized configurations for batching, compression, and memory management.

Quick Start

cd .docker/observability
docker compose up -d

🧪 Specialized Environments

Located in: .docker/compose/

These configurations are tailored for specific testing scenarios that require complex topologies.

Distributed Cluster (4-Nodes)

Simulates a real-world distributed environment with 4 RustFS nodes running locally.

docker compose -f .docker/compose/docker-compose.cluster.yaml up -d

Integrated Observability Test

A self-contained environment running 4 RustFS nodes alongside the full observability stack. Useful for end-to-end testing of telemetry.

docker compose -f .docker/compose/docker-compose.observability.yaml up -d

📡 MQTT Integration

Located in: .docker/mqtt/

Provides an EMQX broker for testing RustFS MQTT features.

Quick Start

cd .docker/mqtt
docker compose up -d

👁️ Alternative: OpenObserve

Located in: .docker/openobserve-otel/

For users preferring a lightweight, all-in-one solution, we support OpenObserve. It combines logs, metrics, and traces into a single binary and UI.

Quick Start

cd .docker/openobserve-otel
docker compose up -d

🔧 Common Operations

Cleaning Up

To stop all containers and remove volumes (WARNING: deletes all persisted data):

docker compose down -v

Viewing Logs

To follow logs for a specific service:

docker compose logs -f [service_name]

Checking Status

To see the status of all running containers:

docker compose ps
