DateProjectionStep

class aws_cdk.aws_glue.DateProjectionStep(*, interval, interval_unit)

Bases: object

A required-together interval step for DATE partition projection.

Bundling interval and intervalUnit into one value makes a partial step (one without the other) unrepresentable.

Parameters:

• interval (Union[int, float]) – Interval between partition values.

• interval_unit (DateIntervalUnit) – Unit for the interval.

Example:

# my_database: glue.Database

glue.S3Table(self, "MyTable",
    database=my_database,
    columns=[glue.Column(
        name="data",
        type=glue.Schema.STRING
    )],
    partition_keys=[glue.Column(
        name="date",
        type=glue.Schema.STRING
    )],
    data_format=glue.DataFormat.JSON,
    partition_projection={
        "date": glue.PartitionProjectionConfiguration.date(
            min="2020-01-01",
            max="2023-12-31",
            format="yyyy-MM-dd",
            # `step` bundles interval + unit (supply both or neither). Optional at day
            # precision or coarser; required when the format is sub-day (e.g. hours).
            step=glue.DateProjectionStep(interval=1, interval_unit=glue.DateIntervalUnit.DAYS)
        )
    }
)

Attributes

Interval between partition values.
