# Hammerwork Roadmap
This roadmap outlines planned features for Hammerwork, prioritized by impact level and implementation complexity. Features are organized into phases based on their value proposition to users and estimated development effort.
## Phase 2: Medium Impact, Variable Complexity
*Valuable features for specific use cases or operational efficiency*
### 🗄️ Job Archiving & Retention
Important for compliance and database performance in high-volume systems.
```rust
// Automatic job archiving
let archival_policy = ArchivalPolicy::new()
.archive_completed_after(Duration::from_days(7))
.archive_failed_after(Duration::from_days(30))
.purge_archived_after(Duration::from_days(365))
.compress_archived_payloads(true);
queue.set_archival_policy(archival_policy).await?;
```
### ⚡ Dynamic Job Spawning
Useful for fan-out processing patterns and dynamic workloads.
```rust
// Jobs that create other jobs
let parent_job = Job::new("process_files".to_string(), file_list)
.with_spawn_handler(|job| {
// Spawn child jobs for each file
job.payload.files.iter().map(|file| {
Job::new("process_file".to_string(), json!({"file": file}))
}).collect()
});
```
### 🔌 Webhook & Event Streaming
Important for integration with external systems and real-time notifications.
```rust
// Real-time job events via webhooks
let webhook_config = WebhookConfig::new()
.url("https://api.example.com/job-events")
.events(vec![JobEvent::Completed, JobEvent::Failed])
.with_retry_policy(RetryPolicy::exponential());
// Event streaming to external systems
let event_stream = EventStream::new()
.to_kafka("job-events")
.to_kinesis("job-stream")
.with_filtering(|event| event.priority >= JobPriority::High);
```
## Phase 3: Specialized Features
*Features for specific enterprise or compliance requirements*
### 🔐 Job Encryption & PII Protection
Critical for organizations with strict data protection requirements.
```rust
// Encrypt sensitive job payloads
let job = Job::new("process_payment".to_string(), payment_data)
.with_encryption(EncryptionConfig::AES256)
.with_pii_fields(vec!["credit_card", "ssn"])
.with_retention_policy(RetentionPolicy::DeleteAfter(Duration::from_days(7)));
```
### 🛡️ Access Control & Auditing
Required for enterprise environments with compliance requirements.
```rust
// Role-based access control
let worker = Worker::new(queue, "sensitive_queue".to_string(), handler)
.with_required_permissions(vec!["process_payments", "read_user_data"])
.with_audit_logging(true);
// Audit trail
let audit_log = queue.get_audit_log(&job_id).await?;
```
### 🔗 Message Queue Integration
Valuable for organizations migrating from other queue systems.
```rust
// Integration with external message queues
let bridge = MessageBridge::new()
.from_rabbitmq("amqp://localhost")
.to_hammerwork_queue("external_jobs")
.with_transform(|msg| Job::from_message(msg));
```
## Phase 4: Advanced Scaling Features
*Complex features primarily for large-scale deployments*
### 🚀 Zero-downtime Deployments
Critical for large-scale production systems but complex to implement correctly.
```rust
// Graceful job migration during deployments
let migration = JobMigration::new()
.drain_workers(Duration::from_minutes(5))
.migrate_pending_jobs("old_queue", "new_queue")
.with_rollback_capability();
```
### 🗂️ Queue Partitioning & Sharding
Essential for massive scale but adds significant complexity.
```rust
// Partition jobs across multiple databases
let queue = PartitionedQueue::new()
.add_partition("shard1", postgres_pool1)
.add_partition("shard2", postgres_pool2)
.with_partitioning_strategy(PartitionStrategy::Hash("user_id"));
```
### 🌍 Multi-region Support
Important for global deployments but extremely complex to implement reliably.
```rust
// Cross-region job replication
let geo_config = GeoReplicationConfig::new()
.primary_region("us-east-1")
.replica_regions(vec!["us-west-2", "eu-west-1"])
.with_failover_policy(FailoverPolicy::Automatic);
```
## Implementation Priority
Features are ordered within each phase by priority and should generally be implemented in the following sequence:

2. Job Testing & Simulation
3. Dynamic Job Spawning
4. Webhook & Event Streaming
**Phase 3 (Enterprise Features)**
