@Marvin Is there a way to clear my persisted results cache?

The search in the documentation didn't return information specifically about the

PREFECT_TASKS_REFRESH_CACHE

setting. Given that this setting relates to Prefect configurations, in general, you can set Prefect environment variables in the following ways: 1. From the Cloud UI: The Cloud UI typically does not offer direct access to setting environment variables. Environment variables must often be set within the deployment environment or the machine where the Prefect Agent is running. 2. From Python code: You can set environment variables in Python using the

os

module before starting your Prefect workflow:

python
import os

# Set the PREFECT_TASKS_REFRESH_CACHE environment variable
os.environ["PREFECT_TASKS_REFRESH_CACHE"] = "your_value_here"

3. From the command line: You can set environment variables for your session or script by exporting them in your shell before running Prefect:

bash
export PREFECT_TASKS_REFRESH_CACHE=your_value_here

However, because the documentation search didn't yield exact results, if the

PREFECT_TASKS_REFRESH_CACHE

variable is specific to Prefect 2.x or a particular feature, it's possible that its use is more specialized or not documented in a searchable way. For such instances, Prefect community forums or the Prefect Slack community can be helpful to get guidance from other Prefect users or team members. If

PREFECT_TASKS_REFRESH_CACHE

is not an officially supported Prefect environment variable, and you got this information from other sources, you may want to check the accuracy of this information or see if it's a custom implementation detail specific to a certain workflow or use case.

@Marvin This is the location in the documentation where I found a reference to the setting https://docs.prefect.io/2.14.3/concepts/tasks/#refreshing-the-cache

The excerpts provided from the Prefect documentation do not directly address how to set or get the

PREFECT_TASKS_REFRESH_CACHE

setting. However, they suggest using

prefect config set

for setting global configurations. Based on the pattern presented in the documentation for setting global settings in Prefect 2.x, you would likely use the following command to set the

PREFECT_TASKS_REFRESH_CACHE

setting from the command line:

bash
prefect config set PREFECT_TASKS_REFRESH_CACHE=your_desired_value

And to retrieve this setting, you might use the Prefect CLI to view all configurations, which should include

PREFECT_TASKS_REFRESH_CACHE

if it has been set:

bash
prefect config view

If

PREFECT_TASKS_REFRESH_CACHE

is in the configuration, its value should be displayed in the output from the above command. To ensure we are providing the most accurate information, I would recommend checking the specific section of the Prefect documentation relevant to

PREFECT_TASKS_REFRESH_CACHE

by following the link you have provided and searching for any specific usage instructions. Since my current capabilities do not include browsing external links, it would be best to check the documentation directly for precise details.
