Hi all, coming from a traditional database background of course my first tendency was wanting to auto_increment a primary key somewhere. Not possible with Riak, obviously! :)
I was wondering if anyone has a good link or white paper about short length hash key creation. I want to keep my keys short to save memory with bitcask storage. (using super low-end commodity hardware with limited RAM) One method that seems like it would be OK: just to use some unique/random SHA function on the client side, and then take the first few characters from the start of the string SHA output = 55ca6286e3e4f4fba5d0448333fa99fc5a404a73 check if 55ca key exists -> (not exist) -> use it -> exist -> check 55ca6 -> (not exist) -> use it -> exist -> check 55ca62 -> (not exist) -> use it -> exist -> check 55ca62 -> (not exist) -> use it -> exist -> check 55ca628 -> (not exist) -> use it -> exist -> check 55ca6286 -> (not exist) -> use it -> exist -> check 55ca6286e -> (not exist) -> use it -> etc... But that could involve a lot of back and forth with the server as the key space gets used up... So I thought I would ask on here if there are any nifty ways of generating *short* keys for Riak! Using C# btw, not that it matters :0 Sorry if this is a FAQ I didnt see it on the website :) Thanks, Alex _______________________________________________ riak-users mailing list riak-users@lists.basho.com http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com
