Yuan Tian commented on IOTDB-478:
---------------------------------
Yes, we keep the cache in ChunkLoaderImpl in TsFile module and just rename
that class.
In Server module, we stop using the ChunkLoaderImpl in TsFile. We implement
another two class named 'DiskChunkLoader' and 'MemChunkLoader' to manage cached
RAM in server.
> Redesign the cache in TsFile/Engine

> Project: Apache IoTDB
> Issue Type: Improvement
> Components: Core/Engine, Core/TsFile
> Reporter: Jialin Qiao
> Assignee: Yuan Tian
> Priority: Major
>
> Currently, the ChunkLoaderImpl has an internal cache, which is not used in
> the server. This may cause much gc overhead.
> I suggest removing the cache in ChunkLoaderImpl, leaving ChunkLoader only a
> tool, and redesign the cache in TsFile and server.
