  • Type Parameters:
    T - the row type
    R - the result type

    public interface PartitioningWriter<T,​R>
    A writer capable of writing files of a single type (i.e. data/delete) to multiple specs and partitions.

    As opposed to FileWriter, this interface should be implemented by writers that are not limited to writing to a single spec/partition. Implementations may internally use FileWriters for writing to a single spec/partition.

    Note that this writer can be used both for partitioned and unpartitioned tables.

        void write​(T row,

        Writes a row to the provided spec/partition.
        row - a data or delete record
        spec - a partition spec
        partition - a partition or null if the spec is unpartitioned
