Package org.apache.beam.sdk.io.gcp.bigquery

Class StreamingWriteTables<ElementT>

  • All Implemented Interfaces:
    java.io.Serializable, org.apache.beam.sdk.transforms.display.HasDisplayData
    public class StreamingWriteTables<ElementT>
extends org.apache.beam.sdk.transforms.PTransform<org.apache.beam.sdk.values.PCollection<org.apache.beam.sdk.values.KV<TableDestination,​ElementT>>,​WriteResult>
    This transform takes in key-value pairs of TableRow entries and the TableDestination it should be written to. The BigQuery streaming-write service is used to stream these writes to the appropriate table.

    This transform assumes that all destination tables already exist by the time it sees a write for that table.
