Executive Summary

The Opportunity

After comprehensive research of the Python task queue ecosystem in 2026, we've identified a critical market gap: no library offers a truly serverless-first, SQS-native, async-ready task queue that combines RQ's simplicity with enterprise reliability.

Current State

Celery: 28M downloads/month but complex, slow, poor defaults
Taskiq: Fastest but generic multi-broker (SQS not optimized)
Dramatiq: Great reliability but requires infrastructure
RQ: Simple but slow, no async, Redis-only

SimpleQ's Position

"The Python task queue for AWS. Zero infrastructure, infinite scale, pennies in cost."

We will be:

Simplest - RQ-level developer experience
Cheapest - Serverless, cost-optimized, built-in cost tracking
Most AWS-native - FIFO, deduplication, X-Ray, CloudWatch
Most modern - Async-first, type-safe, Python 3.10+
Most reliable - DLQ, retries, monitoring built-in

Timeline

10 weeks to v2.0 launch:

Weeks 1-2: Foundation (Python 3, boto3, async core)
Weeks 3-4: SQS-native features (FIFO, DLQ, cost tracking)
Weeks 5-6: Developer experience (CLI, dashboard, integrations)
Weeks 7-8: Advanced features (retries, scheduling, multi-region)
Weeks 9-10: Documentation and launch

Strategic Vision

Mission

Build the most developer-friendly, cost-effective, AWS-native task queue for Python, making background job processing on AWS as simple as possible while providing enterprise-grade reliability.

Core Principles

Simplicity First - Five lines of code from install to first job
AWS-Native - Leverage SQS features, don't abstract them away
Cost-Conscious - Track, optimize, and report on costs automatically
Type-Safe - Modern Python with full type hints and validation
Async-First - Native asyncio, not middleware
Production-Ready - DLQ, monitoring, observability out-of-box

Non-Goals

We explicitly choose NOT to:

❌ Support multiple brokers (SQS only)
❌ Support multi-cloud (AWS only)
❌ Build complex workflow orchestration (use Step Functions)
❌ Support Python 2 or Python 3.9
❌ Compete on feature breadth (we compete on focus)

jobs:
  test:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        python-version: ["3.10", "3.11", "3.12"]
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-python@v5
        with:
          python-version: ${{ matrix.python-version }}
      - run: pip install -e ".[dev]"
      - run: ruff check .
      - run: mypy simpleq
      - run: pytest --cov=simpleq --cov-report=xml
      - uses: codecov/codecov-action@v3

Set up pre-commit hooks

# .pre-commit-config.yaml
repos:
  - repo: https://github.com/astral-sh/ruff-pre-commit
    rev: v0.2.0
    hooks:
      - id: ruff
        args: [--fix]
      - id: ruff-format

    rev: v1.8.0
    hooks:
      - id: mypy
        additional_dependencies: [types-all]

Day 3-4: Boto3 Migration

Replace all boto imports with boto3

Update SQS connection handling

# Old (boto)
from boto.sqs import connect_to_region
conn = connect_to_region('us-east-1')

# New (boto3)
import boto3
sqs = boto3.resource('sqs', region_name='us-east-1')

Add async support with aioboto3

import aioboto3

async def get_queue(queue_name: str):
    session = aioboto3.Session()
    async with session.resource('sqs') as sqs:
        queue = await sqs.get_queue_by_name(QueueName=queue_name)
        return queue

Update all queue operations to boto3 API

Day 5-7: Type Hints & Core Async

Add type hints to all existing code

Configure mypy strict mode

# pyproject.toml
[tool.mypy]
python_version = "3.10"
strict = true
warn_return_any = true
warn_unused_configs = true
disallow_untyped_defs = true

Rewrite Queue class with async

from typing import AsyncIterator
import aioboto3
from pydantic import BaseModel

class Queue:
    def __init__(
        self,
        name: str,
        *,
        region: str = "us-east-1",
        fifo: bool = False,
        dlq: bool = False,
    ) -> None:
        self.name = name
        self.region = region
        self.fifo = fifo
        self.dlq = dlq
        self._session = aioboto3.Session()

    async def enqueue(self, job: Job) -> None:
        """Add a job to the queue."""
        async with self._session.resource('sqs') as sqs:
            queue = await sqs.get_queue_by_name(QueueName=self.name)
            await queue.send_message(
                MessageBody=job.serialize(),
                MessageAttributes=job.attributes,
            )

    async def jobs(self) -> AsyncIterator[Job]:
        """Iterate through jobs in the queue."""
        async with self._session.resource('sqs') as sqs:
            queue = await sqs.get_queue_by_name(QueueName=self.name)

            while True:
                messages = await queue.receive_messages(
                    MaxNumberOfMessages=10,
                    WaitTimeSeconds=20,
                )

                for msg in messages:
                    yield Job.deserialize(msg.body)
                    await msg.delete()

Week 2: Job System & Testing

Day 8-10: Job & Task Implementation

Rewrite Job class with Pydantic

from datetime import datetime
from typing import Any, Callable
from pydantic import BaseModel, Field
import json

class Job(BaseModel):
    """A single unit of work."""

    task_name: str
    args: tuple[Any, ...] = Field(default_factory=tuple)
    kwargs: dict[str, Any] = Field(default_factory=dict)
    created_at: datetime = Field(default_factory=datetime.utcnow)
    retry_count: int = 0

    def serialize(self) -> str:
        """Serialize to JSON."""
        return self.model_dump_json()

    @classmethod
    def deserialize(cls, data: str) -> "Job":
        """Deserialize from JSON."""
        return cls.model_validate_json(data)

Implement task decorator with type safety

from typing import Callable, ParamSpec, TypeVar, overload
from pydantic import BaseModel

P = ParamSpec("P")
R = TypeVar("R")

class TaskDecorator:
    def __init__(self, queue: Queue, schema: type[BaseModel] | None = None):
        self.queue = queue
        self.schema = schema

    def __call__(self, func: Callable[P, R]) -> Task[P, R]:
        return Task(func, self.queue, self.schema)

class Task:
    def __init__(
        self,
        func: Callable[P, R],
        queue: Queue,
        schema: type[BaseModel] | None,
    ):
        self.func = func
        self.queue = queue
        self.schema = schema

    async def delay(self, *args: P.args, **kwargs: P.kwargs) -> None:
        """Enqueue this task for background execution."""
        # Validate with schema if provided
        if self.schema:
            validated = self.schema.model_validate(kwargs)
            kwargs = validated.model_dump()

        job = Job(
            task_name=self.func.__name__,
            args=args,
            kwargs=kwargs,
        )
        await self.queue.enqueue(job)

Day 11-12: Worker Implementation

Build async worker

import asyncio
from typing import Callable

class Worker:
    def __init__(
        self,
        queues: list[Queue],
        *,
        concurrency: int = 10,
    ) -> None:
        self.queues = queues
        self.concurrency = concurrency
        self._running = False
        self._tasks: set[asyncio.Task] = set()

    async def work(self, burst: bool = False) -> None:
        """Start processing jobs."""
        self._running = True

        while self._running:
            for queue in self.queues:
                async for job in queue.jobs():
                    # Create task for concurrent execution
                    task = asyncio.create_task(self._process_job(job))
                    self._tasks.add(task)
                    task.add_done_callback(self._tasks.discard)

                    # Limit concurrency
                    if len(self._tasks) >= self.concurrency:
                        await asyncio.wait(
                            self._tasks,
                            return_when=asyncio.FIRST_COMPLETED,
                        )

            if burst:
                break

        # Wait for remaining tasks
        if self._tasks:
            await asyncio.gather(*self._tasks)

    async def _process_job(self, job: Job) -> None:
        """Process a single job."""
        try:
            # Execute the task
            func = TASK_REGISTRY[job.task_name]
            result = await func(*job.args, **job.kwargs)
        except Exception as e:
            # Log error, will be retried via DLQ
            logger.error("Job failed", job=job, error=str(e))
            raise

Day 13-14: Testing Infrastructure

Set up pytest with localstack

# tests/conftest.py
import pytest
import asyncio
from localstack.testing.pytest import fixtures

@pytest.fixture(scope="session")
def event_loop():
    loop = asyncio.get_event_loop_policy().new_event_loop()
    yield loop
    loop.close()

@pytest.fixture
async def sqs_queue(localstack):
    """Create a test SQS queue."""
    import aioboto3

    session = aioboto3.Session()
    async with session.resource(
        'sqs',
        endpoint_url='http://localhost:4566',
    ) as sqs:
        queue = await sqs.create_queue(QueueName='test-queue')
        yield queue
        await queue.delete()

Write comprehensive tests

# tests/test_queue.py
import pytest
from simpleq import Queue, Job

@pytest.mark.asyncio
async def test_enqueue_and_dequeue(sqs_queue):
    queue = Queue("test-queue")

    job = Job(task_name="test_task", args=(1, 2))
    await queue.enqueue(job)

    received = [job async for job in queue.jobs()]
    assert len(received) == 1
    assert received[0].task_name == "test_task"

Achieve 90%+ test coverage

Deliverable Week 1-2:

✅ Modern Python 3.10+ codebase
✅ Boto3 + aioboto3 integration
✅ Native async/await support
✅ Type hints with mypy strict mode
✅ CI/CD with GitHub Actions
✅ 90%+ test coverage
✅ All existing tests passing

Phase 2: SQS-Native Features (Weeks 3-4)

Goal: Implement features that make SimpleQ unique and leverage SQS capabilities

Week 3: FIFO & Deduplication

Day 15-16: FIFO Queue Support

Implement FIFO queue creation

class Queue:
    def __init__(
        self,
        name: str,
        *,
        fifo: bool = False,
        content_based_deduplication: bool = False,
    ) -> None:
        self.name = name
        self.fifo = fifo

        # FIFO queues must end with .fifo
        if fifo and not name.endswith('.fifo'):
            self.name = f"{name}.fifo"

        self.content_based_deduplication = content_based_deduplication

    async def _ensure_queue_exists(self) -> None:
        """Create queue if it doesn't exist."""
        async with self._session.resource('sqs') as sqs:
            try:
                self._queue = await sqs.get_queue_by_name(
                    QueueName=self.name
                )
            except sqs.meta.client.exceptions.QueueDoesNotExist:
                attrs = {}

                    Attributes=attrs,
                )

Add message group ID support

class Task:
    def __init__(
        self,
        func: Callable,
        queue: Queue,
        *,

                group_id = self.func.__name__

        await self.queue.enqueue(job, message_group_id=group_id)

Test FIFO ordering guarantees

@pytest.mark.asyncio
async def test_fifo_ordering():
    queue = Queue("test.fifo", fifo=True)

    # Enqueue 10 jobs in order
    for i in range(10):
        await queue.enqueue(Job(task_name="test", args=(i,)))

    # Verify order is preserved
    results = [job async for job in queue.jobs()]
    assert [j.args[0] for j in results] == list(range(10))

Day 17-18: Message Deduplication

Implement deduplication ID support

class Job(BaseModel):
    task_name: str
    args: tuple
    kwargs: dict
    deduplication_id: str | None = None

    def get_deduplication_id(self) -> str:

        import hashlib
        content = f"{self.task_name}:{self.args}:{self.kwargs}"
        return hashlib.sha256(content.encode()).hexdigest()

Add deduplication to enqueue

async def enqueue(
    self,
    job: Job,
    *,
    message_group_id: str | None = None,
) -> None:
    async with self._session.resource('sqs') as sqs:

            self._queue = await sqs.create_queue(
                QueueName=self.name,
                Attributes=attrs,
            )

Add DLQ inspection methods

class Queue:
    async def get_dlq_jobs(self) -> AsyncIterator[Job]:
        """Iterate through jobs in the dead letter queue."""
        async with self._session.resource('sqs') as sqs:

            )

            for msg in messages:
                yield Job.deserialize(msg.body)

    async def redrive_dlq_jobs(self) -> int:
        """Move jobs from DLQ back to main queue."""
        count = 0
        async for job in self.get_dlq_jobs():
            await self.enqueue(job)
            count += 1
        return count

Day 21-22: Cost Tracking

Implement cost calculator

# simpleq/observability/cost_tracker.py
from dataclasses import dataclass
from datetime import datetime

    def total_cost(self) -> float:
        return sum(m.estimated_cost for m in self._metrics.values())

Integrate cost tracking into Queue

class Queue:

from rich.table import Table

app = typer.Typer()
console = Console()

@app.command()
def report(

        else:  # exponential
            return min(2 ** retry_count * 60, 3600)  # Cap at 1 hour

Integrate retry logic into worker

class Worker:
    async def _process_job(self, job: Job, message) -> None:
        """Process a single job with retry logic."""
        task = TASK_REGISTRY[job.task_name]

Day 33-34: Job Scheduling

Add delayed execution

class Queue:
    async def enqueue(

        job: Job,
        *,
        delay_seconds: int = 0,

        async with self._session.resource('sqs') as sqs:
            queue = await self._get_queue(sqs)

            kwargs = {
                'MessageBody': job.serialize(),
            }

            # SQS supports delays up to 15 minutes
            if delay_seconds > 0:
                kwargs['DelaySeconds'] = min(delay_seconds, 900)

            await queue.send_message(**kwargs)

EventBridge integration for cron

# simpleq/scheduling.py
import boto3
from typing import Callable

class Scheduler:
    def __init__(self, sq: SimpleQ):
        self.sq = sq
        self.eventbridge = boto3.client('events')

    def cron(self, expression: str):
        """Decorator for cron-scheduled tasks."""
        def decorator(func: Callable):
            task = self.sq.task()(func)

            # Create EventBridge rule
            rule_name = f"simpleq-{func.__name__}"
            self.eventbridge.put_rule(

                ScheduleExpression=f"cron({expression})",
                State='ENABLED',
            )

            # Add SQS queue as target
            self.eventbridge.put_targets(
                Rule=rule_name,
                Targets=[{
                    'Id': '1',
                    'Arn': task.queue.arn,
                    'Input': task._create_job_json(),
                }],
            )

            return task

        return decorator

Week 8: Multi-Region & Polish

Day 35-36: Multi-Region Support

Implement region failover

class SimpleQ:
    def __init__(
        self,
        *,
        regions: list[str] | None = None,
        failover: bool = False,
    ):
        self.regions = regions or ['us-east-1']
        self.failover = failover
        self._current_region_idx = 0

    async def queue(self, name: str, **kwargs) -> Queue:
        """Get queue, with region failover if enabled."""
        if not self.failover:
            return Queue(name, region=self.regions[0], **kwargs)

        # Try each region until success
        for i, region in enumerate(self.regions):
            try:
                queue = Queue(name, region=region, **kwargs)
                await queue._ensure_queue_exists()
                self._current_region_idx = i
                return queue
            except Exception as e:
                logger.warning(f"Region {region} failed: {e}")

API Design

Core API

from simpleq import SimpleQ
from pydantic import BaseModel

# Initialize
sq = SimpleQ()

# Define a task with type-safe schema
class EmailData(BaseModel):
    to: str
    subject: str
    body: str

@sq.task(schema=EmailData)
async def send_email(data: EmailData):
    # Send email logic
    print(f"Sending to {data.to}: {data.subject}")

# Enqueue a job
await send_email.delay(
    EmailData(
        to="user@example.com",
        subject="Hello",
        body="World"
    )
)

# Start worker
worker = sq.worker(queues=["default"], concurrency=10)
await worker.work()

FIFO Queue Example

# Create FIFO queue with content-based deduplication
sq = SimpleQ()
queue = sq.queue("orders.fifo", fifo=True, content_based_deduplication=True)

@sq.task(queue=queue, message_group_id=lambda order_id: f"customer-{order_id}")
async def process_order(order_id: str):
    # Orders for same customer processed in order
    pass

await process_order.delay("order-123")

Dead Letter Queue Example

# Queue with DLQ after 3 retries
queue = sq.queue("emails", dlq=True, max_retries=3)

@sq.task(queue=queue, retry_exceptions=[NetworkError])
async def send_email(to: str):
    # Will retry up to 3 times on NetworkError
    # Then move to DLQ
    pass

# Inspect DLQ
async for job in queue.get_dlq_jobs():
    print(f"Failed job: {job}")

# Redrive DLQ jobs back to main queue
count = await queue.redrive_dlq_jobs()
print(f"Redrove {count} jobs")

Cost Tracking Example

sq = SimpleQ()

# Cost tracking is automatic
await process_data.delay(data)

# View costs
cost_tracker = sq.cost_tracker
print(f"Total cost: ${cost_tracker.total_cost():.4f}")

for queue_name, metrics in cost_tracker._metrics.items():
    print(f"{queue_name}: {metrics.total_requests} requests")

CLI Usage

# Start worker
simpleq worker start -q emails -q orders --concurrency 20

# Queue management
simpleq queue create notifications --fifo --dlq
simpleq queue stats emails
simpleq queue list

# Cost reporting
simpleq cost report
simpleq cost report --queue emails --last-30-days

# Dashboard
simpleq dashboard serve --port 8080

# Metrics
simpleq metrics serve --port 9090

Performance Targets

Benchmarks

Target: Top 3 performance (match Dramatiq/Huey)

Test scenario: 20,000 jobs with 10 workers

Library	Target Time	Status
Taskiq	2.03s	🎯 Aspirational
Huey	3.62s	🎯 Target Range
Dramatiq	4.12s	🎯 Target Range
SimpleQ	3-5s	✅ Goal
Celery	11.68s	⚠️ Must Beat
RQ	51.05s	⚠️ Must Beat

Optimization Strategies

Batch Operations - Receive/send 10 messages at once
Long Polling - 20 second waits to reduce API calls
Async/Await - Native asyncio for I/O efficiency
Message Prefetching - Keep workers fed
Connection Pooling - Reuse boto3 sessions

Performance Testing

# tests/performance/benchmark.py
import asyncio
import time
from simpleq import SimpleQ

async def benchmark():
    sq = SimpleQ()

    @sq.task()
    async def noop():
        pass

    # Enqueue 20,000 jobs
    start = time.time()
    for i in range(20_000):
        await noop.delay()
    enqueue_time = time.time() - start

    # Process with 10 workers
    worker = sq.worker(queues=["default"], concurrency=10)
    start = time.time()
    await worker.work(burst=True)
    process_time = time.time() - start

    print(f"Enqueue: {enqueue_time:.2f}s")
    print(f"Process: {process_time:.2f}s")
    print(f"Total: {enqueue_time + process_time:.2f}s")

asyncio.run(benchmark())

Quick Start:

# Quick Start

Install SimpleQ:

\`\`\`bash
pip install simpleq
\`\`\`

Define a task:

\`\`\`python
from simpleq import SimpleQ

sq = SimpleQ()

@sq.task()
async def send_email(to: str, subject: str):
    print(f"Sending {subject} to {to}")
\`\`\`

Enqueue a job:

\`\`\`python
await send_email.delay("user@example.com", "Hello!")
\`\`\`

Start a worker:

\`\`\`bash
simpleq worker start -q default
\`\`\`

That's it! Your first background job is running.

Migration Guide:

# Migrating from Celery

## Key Differences

| Feature | Celery | SimpleQ |
|---------|--------|---------|
| Broker | Many options | AWS SQS only |
| Setup | Complex config | Zero config |
| Async | Middleware | Native |
| Cost | Redis/RabbitMQ hosting | $0.40 per million requests |

## Step-by-Step Migration

### 1. Install SimpleQ

\`\`\`bash
pip install simpleq
\`\`\`

### 2. Replace Celery imports

\`\`\`python
# Before (Celery)
from celery import Celery
app = Celery('myapp', broker='redis://localhost')

# After (SimpleQ)
from simpleq import SimpleQ
sq = SimpleQ()
\`\`\`

### 3. Update task decorators

\`\`\`python
# Before (Celery)
@app.task
def send_email(to, subject):
    ...

# After (SimpleQ)
@sq.task()
async def send_email(to: str, subject: str):
    ...
\`\`\`

Risk Management

Technical Risks

Risk: Performance doesn't meet targets

Mitigation: Extensive profiling, SQS batch operations, async optimization
Contingency: Document trade-offs, continue optimizing post-launch

Risk: AWS API rate limits

Mitigation: Exponential backoff, request throttling, batch operations
Contingency: Document limits, provide configuration options

Risk: Serialization issues with complex objects

Mitigation: JSON primary, CloudPickle fallback, clear documentation
Contingency: Add more serializers if needed

Market Risks

Risk: Celery improves and closes gap

Mitigation: Focus on unique features (FIFO, cost tracking, AWS-native)
Contingency: Continue differentiating, maintain simplicity advantage

Risk: Taskiq gains SQS-native features

Mitigation: Move fast, community engagement, better docs
Contingency: Collaborate or find new differentiators

Risk: Low adoption due to SQS-only

Mitigation: Target AWS-heavy audience, emphasize benefits
Contingency: Consider Redis/RabbitMQ support in future

Execution Risks

Risk: Timeline slips

Mitigation: Weekly checkpoints, ruthless prioritization
Contingency: Cut scope, ship MVP, iterate

Risk: Burnout / resource constraints

Mitigation: Realistic schedule, community contributions
Contingency: Extend timeline, seek help

Risk: Security vulnerability discovered

Mitigation: Security audit, dependency scanning
Contingency: Rapid patch, transparent communication

Next Steps

Immediate Actions (This Week)

✅ Create v2-development branch
✅ Set up GitHub project board
✅ Configure CI/CD pipeline
✅ Begin Phase 1 (Python 3 + boto3 migration)
✅ Recruit contributors (if desired)

Decision Points

Before Starting:

Confirm timeline (10 weeks realistic?)
Determine solo vs team effort
Set up development environment
Finalize scope (anything to cut?)

After Phase 1:

Review performance of async implementation
Validate API design with early testers
Confirm FIFO support is feasible

After Phase 2:

Get feedback on SQS-native features
Validate cost tracking accuracy
Confirm unique value prop is clear

After Phase 3:

User test CLI and dashboard
Validate localstack integration works smoothly
Confirm developer experience meets goals

Before Launch:

Final security audit
Performance benchmarks published
Launch content ready
Community channels ready

Conclusion

SimpleQ v2.0 represents a unique opportunity to become the standard task queue for AWS-native Python applications. Our competitive research shows:

Clear market gap - No SQS-native, async-first, simple queue exists
Strong differentiation - FIFO, cost tracking, type safety are unique
Right timing - Async adoption soaring, AWS growing, serverless trend
Achievable scope - 10 weeks is aggressive but realistic

Success depends on:

Excellent execution on core features
World-class documentation and DX
Strong launch and community building
Maintaining focus (no scope creep)

If we execute well, SimpleQ can:

Become the default choice for Python + AWS
Reach 5,000 stars in 12 months
Support 100+ companies in production
Generate enterprise support revenue

The plan is solid. Let's build it! 🚀
