// Package archive implements the job archive interface and various backend implementations
// Package archive implements the job archive interface and various backend implementations.
//
// The archive package provides a pluggable storage backend system for job metadata and performance data.
// It supports three backend types:
//
// - file: Filesystem-based storage with hierarchical directory structure
// - s3: AWS S3 and S3-compatible object storage (MinIO, localstack)
// - sqlite: Single-file SQLite database with BLOB storage
//
// # Backend Selection
//
// Choose a backend based on your deployment requirements:
//
// - File: Best for single-server deployments with local fast storage
// - S3: Best for distributed deployments requiring redundancy and multi-instance access
// - SQLite: Best for portable archives with SQL query capability and transactional integrity
//
// # Configuration
//
// The archive backend is configured via JSON in the application config file:
//
// {
// "archive": {
// "kind": "file", // or "s3" or "sqlite"
// "path": "/var/lib/archive" // for file backend
// }
// }
//
// For S3 backend:
//
// {
// "archive": {
// "kind": "s3",
// "bucket": "my-job-archive",
// "region": "us-east-1",
// "accessKey": "...",
// "secretKey": "..."
// }
// }
//
// For SQLite backend:
//
// {
// "archive": {
// "kind": "sqlite",
// "dbPath": "/var/lib/archive.db"
// }
// }
//
// # Usage
//
// The package is initialized once at application startup:
//
// err := archive.Init(rawConfig, false)
// if err != nil {
// log.Fatal(err)
// }
//
// After initialization, use the global functions to interact with the archive:
//
// // Check if a job exists
// exists := archive.GetHandle().Exists(job)
//
// // Load job metadata
// jobMeta, err := archive.GetHandle().LoadJobMeta(job)
//
// // Store job metadata
// err = archive.GetHandle().StoreJobMeta(job)
//
// # Thread Safety
//
// All backend implementations are safe for concurrent use. The package uses
// internal locking for operations that modify shared state.
