I want to have "The 10 worst values for each key" from my reducer function (where I must assume the possibility a huge number of values for some keys). What I have pla...

I have a GridView being populated from a non-SQL database that we use internally. One of those fields is a stockroom location. (Example: AAA, AAB, AAC, etc.) In another database (SQL) I keep a list of all stockrooms and give them a weight.

What sorting algorithm or "tricks" could I use to very quickly sort this list, given that it falls out of sort only one item at a time? The data st...
