@Marvin what is this and how best to resolve?
Copy code
Task parameter introspection took 19.636 seconds , exceeding `PREFECT_TASK_INTROSPECTION_WARN_THRESHOLD` of 10.0. Try wrapping large task parameters with `prefect.utilities.annotations.quote` for increased performance, e.g. `my_task(quote(param))`. To disable this message set `PREFECT_TASK_INTROSPECTION_WARN_THRESHOLD=0`

This warning message is indicating that the introspection of task parameters in your Prefect flow is taking longer than the configured threshold (
PREFECT_TASK_INTROSPECTION_WARN_THRESHOLD
) of 10 seconds. Task parameter introspection is the process of analyzing the parameters passed to a task for various internal purposes such as logging and result handling. To resolve this issue, you can improve performance by wrapping large task parameters with
prefect.utilities.annotations.quote
. This will prevent Prefect from introspecting the contents of the quoted object and should speed up the task initialization process. Here's how you can modify your task call:
Copy code
python
from prefect.utilities.annotations import quote

# Assuming your task function is `my_task` and `large_param` is a large parameter causing the slowdown
my_task(quote(large_param))
Additionally, if you want to disable the warning message altogether (which is generally not recommended unless you're sure about the implications), you can set
PREFECT_TASK_INTROSPECTION_WARN_THRESHOLD
to 0. This will prevent the warning from being logged even if the introspection takes a long time:
Copy code
python
import os

# Set the environment variable to disable the introspection warning
os.environ["PREFECT_TASK_INTROSPECTION_WARN_THRESHOLD"] = "0"
Remember that setting the threshold to 0 does not solve the underlying performance issue; it merely suppresses the warning. For more details on this warning or how to use the
prefect.utilities.annotations.quote
function, refer to the Prefect documentation or ask me to perform a search for you.
