> When executing a query, IOTDB needs to read ChunkMetaData first and then use
> it to read ChunkHeader and ChunkData. Currently, deserializing the chunk
> header requires 2 disk read operations. One is reading chunkheader length,
> the other is reading chunkheader content. So we considerate to reduce IO
> operations in chunk header deserialization.
