> 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.
