> Usually, we store encoded block(uncompressed) in blockcache/bucketCache.
> Though we have set the blocksize, after encoding, blocksize is varied. Varied
> blocksize will cause memory fragment problem, which will result in more FGC
> finally.In order to relief the memory fragment, This issue adjusts the
> encoded block to a unified size.
