@Marvin what does this mean? Task parameter introspection took 406.297 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

.

The message you're seeing indicates that the process of inspecting the parameters of a task in your Prefect flow took an unusually long time to complete—at 406.297 seconds, it far exceeds the warning threshold of 10 seconds that's set by the

PREFECT_TASK_INTROSPECTION_WARN_THRESHOLD

environment variable. Prefect uses task parameter introspection to understand the types and default values of task function parameters for various features, like logging and type checking. Under normal circumstances, this is a quick process, but it can become slow if you have very large parameters because Prefect needs to serialize and inspect them, which can be a time-consuming process. The message suggests a solution to improve the performance: wrapping large task parameters with

prefect.utilities.annotations.quote

. This function avoids the serialization and introspection of the quoted parameter, thereby reducing the time taken for task parameter introspection. Here's an example of how you might use it in your task:

python
from prefect import task
from prefect.utilities.annotations import quote

@task
def my_task(param):
    # Task implementation...

# When calling the task, wrap the large parameter with 'quote'
result = my_task(quote(large_param))

It also mentions the option to disable the warning message by setting the

PREFECT_TASK_INTROSPECTION_WARN_THRESHOLD

environment variable to

0

. However, be aware that this will only suppress the warning message and won't solve the underlying performance issue. For more information about quoting parameters, you can check the Prefect documentation or source code. If you need to access this information, let me know, and I can assist you further.
