> BlockInputStream#readChunkFromContainer() reads the whole chunk from disk
> even if we need to read only a part of the chunk.
> This Jira aims to improve readChunkFromContainer so that only that part of
> the chunk file is read which is needed by client plus the part of chunk file
> which is required to verify the checksum.
> For example, lets say the client is reading from index 120 to 450 in the
> chunk. And let's say checksum is stored for every 100 bytes in the chunk i.e.
> the first checksum is for bytes from index 0 to 99, the next for bytes from
> index 100 to 199 and so on. To verify bytes from 120 to 450, we would need to
> read from bytes 100 to 499 so that checksum verification can be done.
