From 2c6018319579563b50757b005c191743d09168f1 Mon Sep 17 00:00:00 2001 From: northpowered Date: Fri, 31 Oct 2025 16:32:20 +0300 Subject: [PATCH 01/11] refactor: enhance documentation and restructure navigation in mkdocs - Updated mkdocs.yml to improve navigation structure by grouping related guides and adding new sections for configuration, advanced usage, FastStream integration, examples, API reference, troubleshooting, and release notes. - Revised README.md to clarify framework features, installation instructions, and quick start guide, including a new example for executing workflows. - Expanded creating_application.md to provide a comprehensive guide on application structure, BoostApp initialization, defining activities and workflows, and adding workers. - Enhanced running_application.md to cover development and production deployment strategies, including Docker and Kubernetes setups, process management, and monitoring. - Improved example applications to demonstrate various features of Temporal-boost, including FastStream integration and custom worker configurations. This commit aims to provide clearer guidance for users and improve the overall documentation experience. --- .cursor/worktrees.json | 5 + README.md | 225 ++++---- docs/advanced_usage.md | 547 ++++++++++++++++++ docs/api_reference.md | 432 ++++++++++++++ docs/configuration.md | 448 ++++++++++++++ docs/creating_application.md | 739 +++++++++++++++++++++--- docs/examples.md | 703 ++++++++++++++++++++++ docs/faststream_integration.md | 271 +++++++++ docs/index.md | 170 ++++-- docs/running_application.md | 565 +++++++++++++++++- docs/troubleshooting.md | 573 ++++++++++++++++++ examples/README.md | 204 +++++++ examples/example_app.py | 77 ++- examples/example_client.py | 181 ++++++ examples/example_cron.py | 63 ++ examples/example_ecommerce.py | 168 ++++++ examples/example_error_handling.py | 143 +++++ examples/example_fastapi.py | 146 +++++ examples/example_faststream_advanced.py | 156 +++++ examples/example_faststream_producer.py | 98 ++++ examples/example_faststream_temporal.py | 127 ++++ examples/example_parallel.py | 98 ++++ examples/example_signals.py | 74 +++ examples/example_simple_faststream.py | 34 +- examples/example_starter.py | 65 ++- mkdocs.yml | 12 +- 26 files changed, 6001 insertions(+), 323 deletions(-) create mode 100644 .cursor/worktrees.json create mode 100644 docs/advanced_usage.md create mode 100644 docs/api_reference.md create mode 100644 docs/configuration.md create mode 100644 docs/examples.md create mode 100644 docs/faststream_integration.md create mode 100644 docs/troubleshooting.md create mode 100644 examples/README.md create mode 100644 examples/example_client.py create mode 100644 examples/example_cron.py create mode 100644 examples/example_ecommerce.py create mode 100644 examples/example_error_handling.py create mode 100644 examples/example_fastapi.py create mode 100644 examples/example_faststream_advanced.py create mode 100644 examples/example_faststream_producer.py create mode 100644 examples/example_faststream_temporal.py create mode 100644 examples/example_parallel.py create mode 100644 examples/example_signals.py diff --git a/.cursor/worktrees.json b/.cursor/worktrees.json new file mode 100644 index 0000000..77e9744 --- /dev/null +++ b/.cursor/worktrees.json @@ -0,0 +1,5 @@ +{ + "setup-worktree": [ + "npm install" + ] +} diff --git a/README.md b/README.md index 8f1b182..44c0f82 100644 --- a/README.md +++ b/README.md @@ -6,174 +6,161 @@ [![PyPI](https://img.shields.io/pypi/v/temporal-boost.svg?style=for-the-badge)](https://pypi.org/project/temporal-boost) [![MIT](https://img.shields.io/pypi/l/temporalio.svg?style=for-the-badge)](LICENSE) -Documentation is available on [GitHub Pages](https://northpowered.github.io/temporal-boost/) +**Temporal-boost** is a lightweight, high-level framework for rapid development of Temporal-based microservices in Python.

activities=[...], + max_concurrent_activities=100, + max_concurrent_workflow_tasks=50, + nonsticky_to_sticky_poll_ratio=0.1, # Prefer sticky workflows +) +``` + +### Sticky Workflows + +Sticky workflows keep workflow state in memory, improving performance: + +```python +# High sticky ratio for better performance +worker.configure_temporal_runtime( + # Worker polls are configured at worker level +) + +# In worker configuration +worker = app.add_worker( + "sticky_worker", + "sticky_queue", + workflows=[MyWorkflow], + nonsticky_to_sticky_poll_ratio=0.1, # 10% non-sticky, 90% sticky +) +``` + +### Connection Pooling + +Temporal SDK handles connection pooling automatically, but you can optimize: + +```python +# Multiple workers share the same runtime (default) +# For better resource usage, configure shared runtime + +runtime_builder = TemporalRuntimeBuilder( + prometheus_bind_address="0.0.0.0:9090", +) + +runtime = runtime_builder.build() + +# Use same runtime for multiple workers +worker1 = app.add_worker("worker1", "queue1", activities=[...]) +worker1.configure_temporal_client(...) +# Runtime is shared automatically +``` + +### Activity Result Caching + +For expensive activities that can be cached: + +```python +from functools import lru_cache +from temporalio import activity + +# Cache at activity level (use with caution) +@activity.defn(name="cached_activity") +async def cached_activity(key: str) -> str: + return expensive_operation(key) + +# Or implement caching in workflow +@workflow.defn(sandboxed=False, name="CachedWorkflow") +class CachedWorkflow: +

workflow.execute_activity( + cached_activity, + key, + task_queue="cache_queue", + start_to_close_timeout=timedelta(minutes=5), + ) + self._cache[key] = result + return result +``` + +## Advanced Patterns + +### Workflow Versioning + +```python +@workflow.defn(sandboxed=False, name="VersionedWorkflow") +class VersionedWorkflow: + @workflow.run + async def run(self, data: dict) -> dict: + version = data.get("version", 1) + + if version == 1: + return await self._run_v1(data) + elif version == 2: + return await self._run_v2(data) + else: + raise ValueError(f"Unsupported version: {version}") + + async def _run_v1(self, data: dict) -> dict: + # V1 logic + pass + + async def _run_v2(self, data: dict) -> dict: + # V2 logic + pass +``` + +### Custom Data Converter + +```python +from temporalio.converter import DataConverter, PayloadCodec +from temporal_boost.temporal.client import TemporalClientBuilder + +class CustomPayloadCodec(PayloadCodec): + def encode(self, payloads: list[Payload]) -> list[Payload]: + # Custom encoding logic + return payloads + + def decode(self, payloads: list[Payload]) -> list[Payload]: + # Custom decoding logic + return payloads +

Enhanced the CI configuration by adding separate linting jobs for code and examples, utilizing Ruff for linting and formatting checks. - Updated the documentation deployment workflow to include caching of Poetry dependencies and improved steps for building and deploying documentation to GitHub Pages. - Upgraded action versions for better performance and reliability. These changes aim to streamline the CI process, improve code quality checks, and ensure efficient documentation deployment. --- .github/workflows/ci_prepare.yml | 245 ++++++++++++++++++++++------ .github/workflows/documentation.yml | 53 +++++- PR_DESCRIPTION.md | 194 ++++++++++++++++++++++ 3 files changed, 438 insertions(+), 54 deletions(-) create mode 100644 PR_DESCRIPTION.md diff --git a/.github/workflows/ci_prepare.yml b/.github/workflows/ci_prepare.yml index 41faf78..1e89fb3 100644 --- a/.github/workflows/ci_prepare.yml +++ b/.github/workflows/ci_prepare.yml @@ -1,53 +1,202 @@ name: CI on: -

Changed actions in CI workflows to use specific commit SHA versions for better stability and predictability. - Updated `actions/checkout`, `actions/setup-python`, `snok/install-poetry`, `actions/cache`, `codecov/codecov-action`, and `actions/upload-artifact` to their respective commit SHA references. - Added a step to add Poetry to the PATH in multiple workflows to ensure it is accessible during the build process.
