      Description

      IOEngine#read() is called by BucketCache#getBlock().

      IOEngine#read() should return the number of bytes transferred so that BucketCache#getBlock() can check this return value against the length obtained from bucketEntry.

        Nite: ByteBufferArray#getMultiple() returns int now.Better add @return here also. Can fix on commit.

        ByteBufferArray#getMultiple() returns what len passed to it. Fine..
        But then you can handle the ByteBufferIOEngine#read() return value there itself?

        Checking return values is good.

        Why only a log message here? Is this an error? How should it be handled?

        I thought about throwing exception when there is mismatch in length read.
        Here is the method signature for BlockCache#getBlock():

          Cacheable getBlock(BlockCacheKey cacheKey, boolean caching, boolean repeat);
        

        If the above signature is kept, some RuntimeException would be thrown.
        Is that Okay ?
