Pyngres ####### Platform independent applications using Actian Ingres and Vector. ``pyngres`` is a pure Python bindings project for the `Actian Ingres and Vector OpenAPI `_. [#]_ Pyngres is available for Windows, Linux, and MacOS/Darwin. It is intended to support the development of everything from robust, high-performance enterprise applications delivered using thin or fat clients, to embedded Internet-of-Things (IoT) applications. There is nothing you can do with C that you cannot do with Python using pyngres. Many things are easier and more convenient using pyngres than using the OpenAPI in C code. This makes pyngres an excellent tool for learning and prototyping, as well as application development. Pyngres supports: * native communication using the Ingres GCA, without ODBC/JDBC/.Net * Python asyncio awaitable OpenAPI functions * asynchronous callback to Python functions (with Python object closures) * multiple concurrent Ingres sessions without multithreading * native Ingres GCA tracing * the entire Ingres SQL language, including the proprietary extensions * query plan caching * asynchronous database event (DBEVENT) notification * database message handling * 2-phase commit and XA transactions * API-level tracing using `loguru `_ * all the Ingres performance diagnostic tracing capabilities, including: * execution plan (QEP) display * lock tracing * I/O tracing * log tracing Pyngres is compatible with ``asyncio``, `pyside6.QtAsyncio `_, or with any other package having a Python asyncio-compatible event-loop. It can therefore be used to develop rich, responsive GUI database applications as well as back-end logic to be hosted by an application server for SaaS. .. toctree:: :caption: Contents: :maxdepth: 2 :hidden: getting-started hello-pyngres openapi-protocol pyngres-reference debugging ctypes pyngres-examples ..
