01:11:50 GMT <narkewoody> Hello!
01:12:38 GMT <narkewoody> Does AOF mean every time my server boot up, it will take a very long time to recreate the database?
08:06:50 GMT <antirez> itamarhaber: yes sure
08:07:14 GMT <antirez> itamarhaber: 9 chars with 64 symbols = 56 bits, + 10 bit of "encoding version" = 64 bit
08:07:45 GMT <antirez> itamarhaber: so when we save types in the RDB, we can use a 64 bit prefix immediately after the "MODULE TYPE" byte, in order to identify what follows.
08:08:29 GMT <antirez> itamarhaber: yet each value-prefix is not just able to locate the right module to call the callbacks, but also if no match is found, from this ID we can reconstruct the type name to give an hint to the user
08:09:31 GMT <antirez> itamarhaber: so signatures are actually 8 bytes, since we shift the 6 bits characters of the name... into 7 bytes (with 2 bits spare)
08:10:45 GMT <antirez> itamarhaber: note that avoiding uppercase letters, one could use a longer type identifier, but since the length is fixed to force the author to come up with a 18 chars unique string sounded like a bit odd :-)
08:10:54 GMT <antirez> also long as TYPE reply
08:11:08 GMT <antirez> so... 9 chars but with a more interesting charset: A-Z a-z 0-9 - _
08:11:31 GMT <antirez> My-Type12
08:11:54 GMT <antirez> AZ-bloomF
08:12:02 GMT <antirez> it's not hard to find an unique name
08:12:10 GMT <antirez> especially using the name-author trick (or the reverse)
