Hi! I have assets partitioned in 5-min time windows. I only care about the materializations on the current day. As such, I defined my partition as:

realtime_partitions_def = TimeWindowPartitionsDefinition(
    cron_schedule="*/5 * * * *",
    start=pd.Timestamp("now", tz=TIMEZONE).normalize().strftime(realtime_fmt),
    timezone=TIMEZONE,
    fmt=realtime_fmt,
)

I have some related questions: • How often will Dagit reload this definition causing the partition

start

to be updated? • Even if I update the partition

start

, I guess there will be residual data in the dagster DB regarding previous days partitions. How can I clean it up? EDIT: Also posted as a GitHub Discussion
