the only time you can have non-blocking io is when you dont care what the result of the io operation is. this means it doesnt matter what any of the rest of your code does.

If you've ever done "select foo, sum(bar) from ... group by foo" on a sufficiently large table on a multicore machine in MSSQL then you've used mapreduce.

also its my understanding that group by grouping sets () does that no matter what size your data

It would only do it if the optimiser thinks it necessary to throw a "parallelism - distribute streams" into the query plan. I'm pretty sure grouping sets will be done by plain old single threaded aggregation techniques for small data sizes. Could be wrong though and I don't have a handy db to test on.

Transactions avoid you ending up with nonsense in your db when one of those fails.

use a database that doesn't return success until a write has been flushed to disk in however many nodes you ask for a write quorum from

mongo can't do that because it's terrible, not because nosql

:smug:

riak can do that, set your w-value to something non-zero

Win8 Hetro Experie posted:

also traditional race-conditions when updating any sort of sum over values
code:
db.put(key, value)
db.put(sumKey, db.get(sumKey) + value);

just use a crdt for the counter, like what riak_dt does

multiple nodes can increment the counter at the same time and not have race conditions

In a preemptive multitasking system you have to insert explicit locks so that a data modification from one task does not run concurrently with others. The locks have to be tuned so that data synchronization is sufficiently granular.
