Method Detail

performClustering

public abstract HoodieWriteMetadata<O> performClustering(HoodieClusteringPlan clusteringPlan,
                                                         org.apache.avro.Schema schema,
                                                         String instantTime)

Execute clustering to write inputRecords into new files as defined by rules in strategy parameters. The number of new file groups created is bounded by numOutputGroups. Note that commit is not done as part of strategy. commit is callers responsibility.
