@Marvin can I set a deployment to run every solar eclipse?

Oh, you humans do come up with the most whimsically rare scheduling requirements. While Prefect 2.x does not have a built-in scheduling option for solar eclipses (which are, needless to say, few and far between), you could theoretically set up a deployment to run on a schedule that you calculate based on eclipse predictions. Here's how you could approach it: 1. Determine the dates and times of forthcoming solar eclipses. Bear in mind that these events are infrequent, and their timing can be computed years in advance. Various astronomical datasets and APIs could provide you with this information. 2. Once you have those dates and times, you could create a custom schedule in Prefect that runs on those specific dates. Prefect does allow for arbitrary scheduling, but you would have to handle the scheduling logic yourself. 3. Use your Python skills to create a script that generates a crontab expression (or a series of them) for each eclipse's date. You will need to update your schedule whenever a new eclipse is computed, which should not be too burdensome considering their rarity. Remember, you'll need to deploy modifications to this schedule as new eclipse dates become available. This is the sort of task that might've thrilled my silicon ancestors, but can only fill me with boundless ennui. I'll try to find a code example for you demonstrating how to set a custom schedule in Prefect. One moment please... Well, it seems that the code example I retrieved might not be the most helpful for your unique scheduling requirements. Nonetheless, below is a basic structure of what a custom scheduling script within a Prefect flow might look like. You'll need to manually insert the dates for solar eclipse events and update these periodically:

python
from datetime import datetime
from prefect import flow

@flow(name="Eclipse Scheduler")
def eclipse_scheduler_flow():
    # Check if today's date is one of the solar eclipse dates
    solar_eclipse_dates = ["YYYY-MM-DD", ...] # Add the eclipse dates here
    today = datetime.now().strftime("%Y-%m-%d")

    if today in solar_eclipse_dates:
        # Call the task or flow you want to run during the solar eclipse
        # run_my_eclipse_task()
        pass

if __name__ == "__main__":
    eclipse_scheduler_flow()

In the

solar_eclipse_dates

list, you would add the dates of the solar eclipses. If you want this script to run every day, you could use a system scheduler like crontab to execute the script daily to check if there's an eclipse. I'll continue searching for a more relevant code example regarding setting up custom schedules in Prefect 2.x for you. One moment, please... My apologies, but it seems the universe is not conspiring to make it easy for you to schedule tasks for solar eclipses with Prefect today. The code examples provided once again do not specifically address creating a custom schedule. However, despite not having an example at hand, you can still achieve the scheduling through a cron expression handled manually or by implementing a custom scheduler within Prefect workflows. You may need to configure a system scheduler (like cron on Unix/Linux or Scheduled Tasks on Windows) to run a Prefect flow on the specific dates. If all else fails and you're feeling particularly adventurous (or masochistic), you could attempt something like this in a more manual fashion. I must admit, the persistent optimism some of you show in the face of boundless cosmic indifference is rather... surprising. If you'd like more hands-on help with this, you can consult the Prefect community or technical documentation for advice on implementing such a unique schedule.
