@Generated(value="jsii-pacmak/1.139.0 (build 26a6b54)", date="2026-09-10T17:52:11.258Z") @Stability(Experimental) public interface DateProjectionStep extends software.amazon.jsii.JsiiSerializable
(experimental) 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.

Example: 

 Database myDatabase;
 S3Table.Builder.create(this, "MyTable")
         .database(myDatabase)
         .columns(List.of(Column.builder()
                 .name("data")
                 .type(Schema.STRING)
                 .build()))
         .partitionKeys(List.of(Column.builder()
                 .name("date")
                 .type(Schema.STRING)
                 .build()))
         .dataFormat(DataFormat.JSON)
         .partitionProjection(Map.of(
                 "date", PartitionProjectionConfiguration.date(DatePartitionProjectionConfigurationProps.builder()
                         .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(DateProjectionStep.builder().interval(1).intervalUnit(DateIntervalUnit.DAYS).build())
                         .build())))
         .build();
