Detailed Comparisons

GoQueue vs Apache Kafka

Architecture Philosophy

Aspect	Kafka	GoQueue
Storage	Append-only log	Append-only log
Language	Scala/Java (JVM)	Go (native binary)
Coordination	ZooKeeper or KRaft	etcd (optional)
Memory Model	Page cache	Direct I/O

When to Choose Kafka

✅ Massive scale (millions of messages/sec)
✅ Stream processing with Kafka Streams or ksqlDB
✅ Mature ecosystem (connectors, tools)
✅ Strong community and commercial support

When to Choose GoQueue

✅ Simpler deployment (no JVM, no ZooKeeper)
✅ Priority queues (Kafka doesn’t support)
✅ Delayed messages (native support)
✅ SQS-style reliability (visibility timeouts)
✅ Built-in schema registry
✅ Lower memory footprint

Configuration Comparison

Kafka Producer:

bootstrap.servers=kafka:9092
acks=all
batch.size=16384
linger.ms=5
max.in.flight.requests.per.connection=5
enable.idempotence=true

GoQueue Producer:

producer:
  acks: all
  batchSize: 16384
  lingerMs: 5
  # Idempotence enabled by default

GoQueue vs RabbitMQ

Architecture Philosophy

Aspect	RabbitMQ	GoQueue
Model	AMQP (exchanges, queues, bindings)	Topics & partitions
Routing	Flexible (direct, topic, fanout, headers)	Key-based partitioning
Storage	Queue-based (messages removed on consume)	Log-based (retained)
Protocol	AMQP 0-9-1	HTTP/gRPC

When to Choose RabbitMQ

✅ Complex routing (topic exchanges, headers)
✅ AMQP compatibility required
✅ Message acknowledgment at queue level
✅ Existing RabbitMQ expertise

When to Choose GoQueue

✅ Message replay (reprocess from any offset)
✅ Consumer groups with partition assignment
✅ Higher throughput for ordered streams
✅ Simpler operations (no Erlang)
✅ Kafka-style semantics

Feature Mapping

RabbitMQ Concept	GoQueue Equivalent
Exchange + Queue	Topic
Routing Key	Message Key
Consumer Tag	Member ID
Basic.Ack	/messages/ack
Basic.Nack	/messages/nack
Dead Letter Exchange	DLQ Topic
TTL	Retention + TTL
Priority Queue	Priority Levels

GoQueue vs AWS SQS

Architecture Philosophy

Aspect	SQS	GoQueue
Deployment	Managed service	Self-hosted
Model	Queue (messages deleted after processing)	Log (messages retained)
Ordering	FIFO queues only	All topics ordered within partition
Scaling	Automatic	Manual (partitions)

When to Choose SQS

✅ AWS native applications
✅ Zero operations (fully managed)
✅ Pay-per-use pricing
✅ Lambda integration

When to Choose GoQueue

✅ Multi-cloud/on-premise deployment
✅ Message replay capability
✅ Consumer groups
✅ Higher throughput needs
✅ Cost control at scale
✅ Priority queues

API Comparison

SQS Send:

sqs.send_message(
    QueueUrl=queue_url,
    MessageBody='{"order": "123"}',
    DelaySeconds=60
)

GoQueue Publish:

curl -X POST http://goqueue:8080/topics/orders/messages \
  -d '{"messages": [{"value": "{\"order\": \"123\"}", "delay": "60s"}]}'

GoQueue vs NATS

Architecture Philosophy

Aspect	NATS	GoQueue
Core Model	Pub/sub (ephemeral)	Log-based (persistent)
JetStream	Persistent streams	N/A
Protocol	NATS protocol	HTTP/gRPC
Use Case	Real-time messaging	Durable workloads

When to Choose NATS

✅ Real-time pub/sub
✅ Extremely low latency (<1ms)
✅ Request/reply pattern
✅ Service mesh messaging

When to Choose GoQueue

✅ Durability is critical
✅ Message replay needed
✅ Priority queues
✅ Schema validation
✅ Transactions

GoQueue vs Redis Streams

Architecture Philosophy

Aspect	Redis Streams	GoQueue
Storage	In-memory + AOF/RDB	Disk-first
Model	Stream per key	Topics with partitions
Consumer Groups	Yes	Yes
Clustering	Redis Cluster	Native

When to Choose Redis Streams

✅ Already using Redis
✅ Simple setup
✅ Caching + messaging in one system
✅ Low latency requirements

When to Choose GoQueue

✅ Large message volumes (disk-based)
✅ Longer retention (weeks/months)
✅ Priority queues
✅ Schema registry
✅ Transactions
✅ Visibility timeouts

Use Case Recommendations

Event Sourcing / CQRS

Requirement	Best Choice
Millions of events	Kafka
Moderate scale, simpler ops	GoQueue
AWS native	Kinesis

Task Queues / Job Processing

Requirement	Best Choice
Priority handling	GoQueue or RabbitMQ
AWS integration	SQS
Simple setup	Redis Streams

Real-time Messaging

Requirement	Best Choice
Sub-millisecond latency	NATS
Durability required	GoQueue
Browser support	RabbitMQ (WebSocket)

Log Aggregation

Requirement	Best Choice
Massive scale	Kafka
Simpler deployment	GoQueue
Existing ELK stack	Kafka

Microservices Communication

Requirement	Best Choice
Request/reply	NATS or RabbitMQ
Event-driven	GoQueue or Kafka
AWS native	SQS + SNS

Migration Guides

From Kafka to GoQueue

Key differences to handle:

Configuration: GoQueue uses YAML, not properties files
Consumer Groups: Similar concept, different API
Offsets: Same model, different commit API
Transactions: Similar semantics, different endpoints

# Kafka consumer to GoQueue
# Before (Kafka)
kafka-console-consumer --bootstrap-server kafka:9092 --topic orders --group my-group

# After (GoQueue)
curl -X POST http://goqueue:8080/groups/my-group/join -d '{"topics": ["orders"]}'
curl http://goqueue:8080/groups/my-group/poll?member_id=...

From RabbitMQ to GoQueue

Key differences:

No exchanges: Route by message key to partitions
Consumer groups instead of individual consumers
Log retention: Messages aren’t deleted after consumption

From SQS to GoQueue

Key similarities (easier migration):

Visibility timeouts: Both support this pattern
DLQ: Both have dead letter queues
Delayed messages: Both support scheduling

Performance Considerations

System	Throughput (msgs/sec)	Latency (p99)	Memory
Kafka	1M+	10-50ms	High (JVM)
GoQueue	500K+	5-20ms	Low
RabbitMQ	100K+	1-10ms	Medium
SQS	Unlimited*	20-100ms	N/A
NATS	10M+	<1ms	Low
Redis Streams	500K+	<1ms	High

*SQS scales automatically but has per-request limits

Summary: When to Use GoQueue

✅ Choose GoQueue when you need:

Kafka-style semantics with simpler operations
Priority queues with ordering
Delayed/scheduled messages
SQS-style visibility timeouts
Built-in schema registry
Cloud-native deployment (Kubernetes)
Lower operational complexity than Kafka

❌ Consider alternatives when:

You need millions of messages/sec → Kafka
You’re all-in on AWS → SQS
You need sub-millisecond latency → NATS
You need complex routing → RabbitMQ
You’re already using Redis → Redis Streams
