My 'natural' keys are generally 400 to 900 bytes. I'd like to avoid having to pay the price of either a) creating a good digest (MD5) each time, or b) using a poor digest and including a copy of the full key inside the value (so it can be checked when fetched).
I was surprised that memcached doesn't offer a command like option to support larger key sizes. The image of the binary protocol[1] shows "keylen 3". Does than mean three bytes will be used to store the keylen in the binary protocol? Tim. [1] http://code.sixapart.com/svn/memcached/trunk/server/doc/binary-protocol-plan.jpg
