      public <T> io.activej.promise.Promise<StreamSupplier<T>> read(AggregationStructure aggregation, List<String> fields, Class<T> recordClass, C chunkId, DefiningClassLoader classLoader)
      Description copied from interface: AggregationChunkStorage
      Creates a StreamSupplier that streams records contained in the chunk. The chunk to read is determined by aggregationId and id.

      chunkId - id of chunk
      Returns:
      StreamSupplier, which will stream read records to its wired consumer.
