org.apache.beam.sdk.io.gcp.bigtable.BeamRowToBigtableMutation

All Implemented Interfaces:

java.io.Serializable, org.apache.beam.sdk.transforms.display.HasDisplayData

public class BeamRowToBigtableMutation
extends org.apache.beam.sdk.transforms.PTransform<org.apache.beam.sdk.values.PCollection<org.apache.beam.sdk.values.Row>,org.apache.beam.sdk.values.PCollection<org.apache.beam.sdk.values.KV<com.google.protobuf.ByteString,java.lang.Iterable<com.google.bigtable.v2.Mutation>>>>
implements java.io.Serializable

Bigtable reference: .

Requires a flat schema and a mapping which column family corresponds to which column.

Row represents Bigtable Mutation in the following way:

Mapped Beam Row:

BEAM_ROW: ROW

VALUE: Beam Schema type except for ARRAY, DECIMAL, ITERABLE, MAP, ROW

Mapped Mutation:

mutation: key, setCell[]

setCell: familyName, columnQualifier, ROW[columnQualifier] - familyName comes from the column: family mapping
