`prefect.server.events.counting`

Classes

`InvalidEventCountParameters`

Raised when the given parameters are invalid for counting events.

`TimeUnit`

Methods:

`as_timedelta`

as_timedelta(self, interval: float) -> Duration

`auto`

auto() -> str

Exposes enum.auto() to avoid requiring a second import to use AutoEnum

`database_label_expression`

database_label_expression(self, db: PrefectDBInterface, time_interval: float) -> sa.Function[str]

Returns the SQL expression to label a time bucket

`database_value_expression`

database_value_expression(self, time_interval: float) -> sa.Cast[str]

Returns the SQL expression to place an event in a time bucket

`get_interval_spans`

get_interval_spans(self, start_datetime: datetime.datetime, end_datetime: datetime.datetime, interval: float) -> Generator[int | tuple[datetime.datetime, datetime.datetime], None, None]

Divide the given range of dates into evenly-sized spans of interval units

`validate_buckets`

validate_buckets(self, start_datetime: datetime.datetime, end_datetime: datetime.datetime, interval: float) -> None

`Countable`

Methods:

`auto`

auto() -> str

Exposes enum.auto() to avoid requiring a second import to use AutoEnum

`get_database_query`

get_database_query(self, filter: 'EventFilter', time_unit: TimeUnit, time_interval: float) -> Select[tuple[str, str, DateTime, DateTime, int]]
