@Marvin is there a way to store results from a flow run & retrieve it later ?

Yes, you can store and retrieve results from a flow run in Prefect 3.x. By default, task results are stored in memory, which is efficient for small data but not ideal for larger datasets. For more robust storage, you can write results to disk or use cloud storage services like AWS S3. Here's a quick overview of how you can achieve this: 1. Cloud Storage Integration: Prefect supports integrations with cloud providers through blocks. For instance, you can use the

prefect-aws

library to store results in AWS S3. You'll need to install the relevant library, register the block type with the server, and create your block. Then, reference this block in your flow code to store results externally. 2. Result Storage API: Prefect provides a

ResultStorage

mechanism where you can specify how and where results should be stored. This can be a file system or a cloud storage path. The

ResultStorage

can be customized to fit your needs. 3. Retrieving Results: You can retrieve stored results using the

state.result()

method, which can fetch results from the specified storage. For more detailed information and examples, you can refer to the Prefect documentation on using storage blocks. If you need specific code examples or further assistance, feel free to ask!
