Method Detail

extractPartitionInfo

@Nullable
public static SegmentPartitionInfo extractPartitionInfo(String tableNameWithType,
                                                        String partitionColumn,
                                                        String segment,
                                                        @Nullable
                                                        org.apache.helix.zookeeper.datamodel.ZNRecord znRecord)

Returns the partition info for a given segment with single partition column. NOTE: Returns null when the ZNRecord is missing (could be transient Helix issue). Returns INVALID_PARTITION_INFO when the segment does not have valid partition metadata in its ZK metadata, in which case we won't retry later.

extractPartitionInfoMap

@Nullable
public static Map<String,SegmentPartitionInfo> extractPartitionInfoMap(String tableNameWithType,
                                                                             Set<String> partitionColumns,
                                                                             String segment,
                                                                             @Nullable
                                                                             org.apache.helix.zookeeper.datamodel.ZNRecord znRecord)

Returns a map from partition column name to partition info for a given segment with multiple partition columns. NOTE: Returns null when the ZNRecord is missing (could be transient Helix issue). Returns INVALID_COLUMN_PARTITION_INFO_MAP when the segment does not have valid partition metadata in its ZK metadata, in which case we won't retry later.
