Abstract: Techniques for transmitting a data block involve receiving, from a client, a request for reading the data block. Such techniques further involve determining, at a data block layer, whether the data block needs to be compressed at a protocol layer based on a flag indicating whether the data block has been compressed and a storage size of the data block. Such techniques further involve transferring, in response to determining that the data block does not need to be compressed at the protocol layer, an indication that the data block does not need to be compressed at the protocol layer from the data block layer to the protocol layer. Such techniques further involve sending the data block to the client through the protocol layer without compressing the data block at the protocol layer.
