    • Method Detail

      • strategy

        public final CompactionStrategy strategy()

        The strategy to use for compaction. Valid values are:

        • binpack: Combines small files into larger files, typically targeting sizes over 100MB, while applying any pending deletes. This is the recommended compaction strategy for most use cases.

        • sort: Organizes data based on specified columns which are sorted hierarchically during compaction, improving query performance for filtered operations. This strategy is recommended when your queries frequently filter on specific columns. To use this strategy, you must first define a sort order in your Iceberg table properties using the sort_order table property.

        • z-order: Optimizes data organization by blending multiple attributes into a single scalar value that can be used for sorting, allowing efficient querying across multiple dimensions. This strategy is recommended when you need to query data across multiple dimensions simultaneously. To use this strategy, you must first define a sort order in your Iceberg table properties using the sort_order table property.

        If an input is not provided, the default value 'binpack' will be used.

        If the service returns an enum value that is not available in the current SDK version, strategy will return CompactionStrategy.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from strategyAsString().

        Returns:
