Does IPFS implement Robin fingerprint? #74

Closed sivachandran closed 7 years ago

sivachandran commented 9 years ago

Tried adding a file multiple times after changing few bytes at the start. Every time the 'blocks' directory size increases by full size of the file I am adding. So wondering whether IPFS implements Robin fingerprint based blocking or is it in the roadmap.

Pasting answer from IRC.

whyrusleeping: we implement rabin fingerprinting, but its not in the default sivachandran: how can I enable it? whyrusleeping: ipfs add -s rabin whyrusleeping: you can also specify some parameters to rabin (this isnt well documented yet, i apologize) whyrusleeping: example: set average block size: 'ipfs add -s rabin-128000 ' whyrusleeping: and you can also set min and max block sizes at the same time: 'ipfs add -s rabin 256-4096-8192 ' whyrusleeping: will try to make the average blocksize 4096, but force the blocks to be less than 8192 and greater than 256 whyrusleeping: sorry, '-s rabin-256-4096-8192' whyrusleeping: needs to be a single string as the parameter
