PG-AsynQ
PG-AsynQ is a Python library that provides an asynchronous transaction/message queue based on PostgreSQL. It is inspired by pq, but is built for use in asynchronous contexts such as FastAPI, and uses psycopg 3.x for database access.
Non blocking queuing is implemented with a combination of LISTEN/NOTIFY and SKIP LOCKED. This means that this
library is safe to use across multiple containers/processes without duplicated processing of messages.
How to use
- Ensure you create the tables in migrations using your preferred migration tool
- See the examples for how to use the library
Features
- Create and consume queues dynamically at runtime
- Consume queue from any number of consumers
- Retain messages until a consumer connects
- In-order processing of messages
- Message retention policies (delete older than x)
