# 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 3: Specialized Features (🚧 IN PROGRESS)
*Features for specific enterprise or compliance requirements*
### ✅ Job Encryption & PII Protection (IMPLEMENTED)
Critical for organizations with strict data protection requirements.
**Status**: Core encryption system implemented with AES-256-GCM and ChaCha20-Poly1305 support, PII field detection, and retention policies.
```rust
// Encrypt sensitive job payloads
use hammerwork::{Job, encryption::{EncryptionConfig, EncryptionAlgorithm, RetentionPolicy}};
let job = Job::new("process_payment".to_string(), payment_data)
.with_encryption(EncryptionConfig::new(EncryptionAlgorithm::AES256GCM))
.with_pii_fields(vec!["credit_card", "ssn"])
.with_retention_policy(RetentionPolicy::DeleteAfter(Duration::from_secs(7 * 24 * 60 * 60)));
```
### 🛡️ 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:
**Phase 3 (Enterprise Features)**
1. Job Encryption & PII Protection
2. Access Control & Auditing
3. Message Queue Integration
**Phase 4 (Scaling Features)**
1. Zero-downtime Deployments
2. Queue Partitioning & Sharding
3. Multi-region Support
## Contributing
We welcome contributions to any of these roadmap items! Please:
1. Open an issue to discuss the feature before implementation
