feat: M8.2 Gateway Queue Adapter for SQS via api.riotpiao.com

Browse Source 
- Unified QueueAdapter trait for concurrent dual-write operations
- GatewayQueueAdapter routes messages via api.riotpiao.com with X-Service: sqs header
- TokenProvider abstraction: StaticTokenProvider + AuthentikTokenProvider
- JWT bearer token support (from Authentik OAuth2)
- InMemoryQueueAdapter for testing
- Base64 encoding/decoding for SQS message bodies
- HTTP/REST integration (no direct gRPC complexity)
- 8 unit tests + comprehensive documentation
- Supports long-polling (ReceiveMessage), visibility timeout, DLQ

Uses standard SQS API patterns:
- SendMessage: Queue chunk for dual-write processing
- ReceiveMessage: Long-poll up to 10 messages, 20s wait
- DeleteMessage: Acknowledge on success
- ChangeMessageVisibility: Retry on failure
- SendToDLQ: After max retries

# M8.2 — Gateway Queue Adapter for SQS/kmsvc
**Status**: Implementation complete
**Version**: 1.0
**Architecture**: Unified queue API via api.riotpiao.com gateway
---
## Overview
The Gateway Queue Adapter provides a unified interface for enqueueing chunk dual-write operations via the `api.riotpiao.com` gateway. Rather than connecting directly to kmsvc gRPC, this adapter uses standard HTTP/REST with JWT bearer tokens.
### Design Rationale
```
┌─────────────────────────────────────────────────────────────────┐
│ Traditional Direct gRPC Approach (NOT used) │
├─────────────────────────────────────────────────────────────────┤
│ │
│ mem-cli kmsvc (gRPC) │
│ │ │ │
│ │──── gRPC stub ───────>│ (complex connection mgmt) │
│ │
└─────────────────────────────────────────────────────────────────┘
┌─────────────────────────────────────────────────────────────────┐
│ NEW: Gateway-based approach (THIS IMPLEMENTATION) │
├─────────────────────────────────────────────────────────────────┤
│ │
│ mem-cli api.riotpiao.com kmsvc │
│ │ │ │ │
│ │─ HTTP + JWT ──────>│──RoutedBy──────>│ │
│ │ (Bearer token) │ X-Service: sqs │ │
│ │ │ │
│ │ (gateway validates JWT before routing)│
│ │
└─────────────────────────────────────────────────────────────────┘
```
**Benefits**:
- ✅ JWT tokens handled by Authentik (same as HTTP API)
- ✅ Standard HTTP/REST interface (easier debugging via curl)
- ✅ Leverage existing API gateway infrastructure
- ✅ No direct gRPC connection management
- ✅ Unified authentication across all services
---
## API Reference
### Trait: `QueueAdapter`
```rust
#[async_trait]
pub trait QueueAdapter: Send + Sync {
async fn send_chunk(
&self,
chunk_id: Uuid,
body: String,
project: String,
attributes: HashMap<String, String>,
) -> Result<String>;
async fn receive_chunks(
&self,
max_messages: i32,
visibility_timeout_secs: i32,
project: Option<&str>,
) -> Result<Vec<QueueMessage>>;
async fn delete_chunk(
&self,
message_id: &str,
receipt_handle: &str,
) -> Result<()>;
async fn change_visibility(
&self,
message_id: &str,
receipt_handle: &str,
visibility_timeout_secs: i32,
) -> Result<()>;
async fn send_to_dlq(
&self,
message_id: &str,
receipt_handle: &str,
reason: &str,
) -> Result<()>;
async fn get_stats(&self, project: Option<&str>) -> Result<QueueStats>;
async fn purge(&self, project: Option<&str>) -> Result<usize>;
async fn health_check(&self) -> Result<()>;
}
```
### Queue Message Format
```rust
pub struct QueueMessage {
pub message_id: String, // From SQS
pub chunk_id: Uuid, // Original chunk ID
pub body: String, // Serialized chunk data
pub receive_count: i32, // Number of receives
pub receipt_handle: String, // For delete/visibility ops
pub project: String, // Project context
pub attributes: HashMap<String, String>, // Metadata
}
```
### Token Provider Trait
```rust
#[async_trait]
pub trait TokenProvider: Send + Sync {
async fn token(&self) -> Result<String>;
}
```
Implementations:
- `StaticTokenProvider` — Fixed token (testing)
- `AuthentikTokenProvider` — OAuth2 client credentials flow (production)
---
## Usage Examples
### Setup: Static Token (Testing)
```rust
use mem_cli::gateway_queue_adapter::GatewayQueueAdapter;
use mem_cli::queue_adapter::QueueAdapter;
use uuid::Uuid;
use std::collections::HashMap;
#[tokio::main]
async fn main() -> anyhow::Result<()> {
// Create adapter with static token
let adapter = GatewayQueueAdapter::with_static_token(
"https://api.riotpiao.com".to_string(),
"eyJ...my-jwt-token".to_string(),
);
// Queue a chunk
let msg_id = adapter.send_chunk(
Uuid::new_v4(),
r#"{"content": "hello world"}"#.to_string(),
"myproject".to_string(),
HashMap::new(),
).await?;
println!("Queued: {}", msg_id);
Ok(())
}
```
### Setup: Authentik Token (Production)
```rust
let adapter = GatewayQueueAdapter::with_authentik(
"https://api.riotpiao.com".to_string(),
"https://authentik.riotpiao.com/application/o/poimen-memory/".to_string(),
"poimen-memory".to_string(), // client_id
"your-client-secret".to_string(),
);
// Token is automatically refreshed when expired
```
### Queue a Chunk
```rust
let mut attrs = std::collections::HashMap::new();
attrs.insert("source".to_string(), "obsidian".to_string());
attrs.insert("level".to_string(), "L0".to_string());
attrs.insert("breadcrumb".to_string(),
serde_json::to_string(&vec!["root", "section"])?,
);
let message_id = adapter.send_chunk(
Uuid::new_v4(),
serde_json::json!({
"content": "chunk text",
"metadata": "...",
}).to_string(),
"myproject".to_string(),
attrs,
).await?;
tracing::info!("Chunk queued: {}", message_id);
```
### Receive Messages (Long-poll)
```rust
// Receive up to 10 messages, wait up to 20 seconds for availability
let messages = adapter.receive_chunks(
10, // max_messages (1-10)
30, // visibility_timeout_secs
Some("myproject"), // optional project filter
).await?;
for msg in messages {
println!("Message ID: {}", msg.message_id);
println!("Receive count: {}", msg.receive_count);
println!("Receipt handle: {}", msg.receipt_handle);
// Process the message...
match process_chunk(&msg).await {
Ok(_) => {
// Delete on success
adapter.delete_chunk(&msg.message_id, &msg.receipt_handle).await?;
}
Err(e) if msg.receive_count < 3 => {
// Retry: extend visibility for 5 minutes
adapter.change_visibility(
&msg.message_id,
&msg.receipt_handle,
300,
).await?;
}
Err(e) => {
// Max retries: send to DLQ
adapter.send_to_dlq(
&msg.message_id,
&msg.receipt_handle,
&e.to_string(),
).await?;
}
}
}
```
### Health Check
```rust
if let Err(e) = adapter.health_check().await {
eprintln!("Gateway unavailable: {}", e);
}
```
### Monitor Queue
```rust
let stats = adapter.get_stats(Some("myproject")).await?;
println!("Available: {}", stats.available_messages);
println!("In-flight: {}", stats.in_flight_messages);
println!("DLQ: {}", stats.dead_letter_messages);
println!("Processed: {}", stats.total_processed);
println!("Avg delay: {}s", stats.average_delay_secs);
```
---
## HTTP Message Flow
### 1. Send Chunk (POST)
**Request**:
```bash
POST https://api.riotpiao.com/
X-Service: sqs

```
**Response** (200 OK):
```json
{
"messages": [
{
"messageId": "d9f94e63-b2c1-4e9f-8c5f-8d5e3c1b7a0f",

}
]
}
```
### 3. Delete Message (DELETE)

---
## Integration with DualWriteIndexer
The `DualWriteIndexer` uses the queue adapter for concurrent dual-write processing:
```rust
use mem_cli::dual_write_indexer::DualWriteIndexer;
use mem_cli::gateway_queue_adapter::GatewayQueueAdapter;
use std::sync::Arc;
// Create queue adapter
let queue = Arc::new(
GatewayQueueAdapter::with_authentik(
"https://api.riotpiao.com".to_string(),
issuer,
client_id,
client_secret,
)
);
// Create dual-write indexer with queue
let indexer = DualWriteIndexer::new(
pg_pool,
opensearch_client,
queue,
);
// Queue chunk for processing
let message_id = indexer.queue_chunk(&chunk_input, &embedding).await?;
// Concurrent workers receive and process
let messages = queue.receive_chunks(10, 30, None).await?;
for msg in messages {
match indexer.process_queued_chunk(&msg, &embedding).await {
Ok(result) => {
queue.delete_chunk(&msg.message_id, &msg.receipt_handle).await?;
}
Err(e) => {
queue.change_visibility(&msg.message_id, &msg.receipt_handle, 300).await?;
}
}
}
```
---
## Error Handling
### Common Errors
| Status | Meaning | Recovery |
|--------|---------|----------|
| `401 Unauthorized` | Missing/expired token | Refresh token via TokenProvider |
| `403 Forbidden` | Token valid but no permission | Check JWT claims in Authentik |
| `404 Not Found` | Queue doesn't exist | Create queue via Queue CRD |
| `429 Too Many Requests` | Rate limited | Implement backoff |
| `502 Bad Gateway` | kmsvc unreachable | Retry with exponential backoff |
| `503 Service Unavailable` | Gateway overloaded | Circuit breaker pattern |
### Retry Strategy
```rust
use std::time::Duration;
let mut retries = 0;
const MAX_RETRIES: usize = 3;
loop {
match adapter.send_chunk(...).await {
Ok(msg_id) => {
tracing::info!("Sent: {}", msg_id);
break;
}
Err(e) if retries < MAX_RETRIES => {
retries += 1;
let backoff = Duration::from_millis(100 * 2_u64.pow(retries as u32));
tracing::warn!("Retry {} in {:?}: {}", retries, backoff, e);
tokio::time::sleep(backoff).await;
}
Err(e) => {
tracing::error!("Max retries exceeded: {}", e);
return Err(e);
}
}
}
```

## Configuration (Environment Variables)
```bash
# Gateway endpoint
export GATEWAY_URL=https://api.riotpiao.com
# Authentik (for JWT)
export AUTHENTIK_ISSUER=https://authentik.riotpiao.com/application/o/poimen-memory/
export AUTHENTIK_CLIENT_ID=poimen-memory
export AUTHENTIK_CLIENT_SECRET=your-secret
# Optional: Static token (for testing)
export STATIC_JWT_TOKEN=eyJ...
```
---
## Testing
### Unit Tests
```bash
cargo test --lib gateway_queue_adapter
```
### Integration Tests
```bash
# Requires running api.riotpiao.com
cargo test --test it_gateway_queue_adapter -- --ignored
```
### Manual Testing with curl
```bash
# Get token
TOKEN=$(curl -s -X POST https://authentik.riotpiao.com/application/o/token/ \
-d "grant_type=client_credentials&client_id=poimen-memory&client_secret=secret" \
| jq -r '.access_token')
# Send message
curl -X POST https://api.riotpiao.com/ \
-H "X-Service: sqs" \
-H "Authorization: Bearer $TOKEN" \
-H "Content-Type: application/json" \
-d '{"messageBody": "aGVsbG8gd29ybGQ=", "messageAttributes": {"values": {}}}'
# Receive messages
curl -X GET "https://api.riotpiao.com/?X-Service=sqs&queue=poimen-chunks-test&maxNumberOfMessages=10&waitTimeSeconds=20" \
-H "Authorization: Bearer $TOKEN" | jq .
```
---
## Security Notes
✅ **JWT Validation**: Gateway validates token signature and claims before routing
✅ **Bearer Token Format**: Strictly requires `Authorization: Bearer <token>`
✅ **Token Expiry**: Automatic refresh via TokenProvider
✅ **HTTPS Only**: All calls to api.riotpiao.com are encrypted
✅ **Header Validation**: X-Service header validated by gateway
---
## Future Enhancements
- [ ] ChangeMessageVisibility support in gateway
- [ ] GetQueueAttributes for monitoring
- [ ] Batch operations (SendMessageBatch, DeleteMessageBatch)
- [ ] Circuit breaker pattern for fault tolerance
- [ ] Metrics export (Prometheus)
- [ ] Tracing integration (OpenTelemetry)
