To set up partitions that run for the current day, you can use the
end_offset
parameter when defining your partitions. The
end_offset
parameter allows you to extend the partition set by a number of partitions equal to the value passed. If
end_offset
is set to 0 (the default), the last partition ends before the current time. By setting
end_offset
to 1, you can create a partition for the current day. Here's an example of how you might define a daily partition with an
end_offset
to include the current day:
Copy code
python from dagster import DailyPartitionsDefinition  daily_partitions_def = DailyPartitionsDefinition(     start_date="2021-01-01",     end_offset=1,  # This allows there to be a partition for the current day )
In this example, the
DailyPartitionsDefinition
is used to create daily partitions starting from a specific date, and the
end_offset=1
ensures that there is a partition for the current day. If you are trying to use
hour_offset
and it's not working as expected, it's important to ensure that you are using the correct partition definition and that the
hour_offset
is being applied in the right context. The
hour_offset
is typically used with time-based partition definitions like
HourlyPartitionsDefinition
or
TimeWindowPartitionsDefinition
. If you continue to face issues, please provide more details about your current setup, including the code you're using to define your partitions and how you're attempting to use
hour_offset
. This will help us give you more specific guidance.
