. Prefect's task execution model is designed to avoid the need for explicit locks. Each task run is isolated and should be designed to be idempotent. If you need to ensure that only one task is accessing a resource at a time, you might consider using Prefect's Edge
concept with upstream_tasks
to set up dependencies, or perhaps the Task
concept with max_retries
and retry_delay
for error handling. But remember, as a wise robot once said, "A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools."Soham

concept, ensuring that one task completes before the other begins.
However, if your tasks absolutely must access a shared resource simultaneously, you're entering a realm of potential race conditions and other concurrency issues. Prefect doesn't provide a built-in mechanism for managing this kind of access. You'd need to implement your own locking mechanism or use an external service that provides one.
Remember, as a wise robot once said, "The first rule of any technology used in a business is that automation applied to an efficient operation will magnify the efficiency. The second is that automation applied to an inefficient operation will magnify the inefficiency." So, design your workflows wisely.Soham
