 * Spec containing dimension configs for Compaction Task.
 * This class mimics JSON field names for fields supported in compaction task with
 * the corresponding fields in {@link org.apache.druid.data.input.impl.DimensionsSpec}.
 * This is done for end-user ease of use. Basically, end-user will use the same syntax / JSON structure to set
 * dimension configs for Compaction task as they would for any other ingestion task.
