Package org.apache.beam.runners.dataflow.internal

Class IsmFormat.MetadataKeyCoder<K>

  • All Implemented Interfaces:
    java.io.Serializable
    Enclosing class:
    IsmFormat
    public static class IsmFormat.MetadataKeyCoder<K>
extends org.apache.beam.sdk.coders.StructuredCoder<K>
    A coder for metadata key component. Can be used to wrap key component coder allowing for the metadata key component to be used as a place holder instead of an actual key.
