We're Awesome

README driven development! Here we go!

Anansi (why is it called like that?) is a distributed MapReduce implementation for JavaScript that runs on the worlds largest computational network. Consumer PCs.

Trade-offs

Technically there is no reason not to run MapReduce jobs on idling web clients. But of course this was a competition and we had to spend some time to implement cool realtime scrolling graphs, so some things were left out.

• There is no input reader step. Data has to be uploaded in chunks.
• There's always exactly one map phase and one reduce phase. No partitions and you can't supply a partitioning function.
• The grouping step after the map step is lame and slow.
• Results aren't validated by more than one client.
• We're using a relational database goes and hides in the basement
