we use delayedjob run of our long running processes , test cucumber/webrat. currently, calling delayed::job.work_off in ruby thread work done in background, looking more robust solution what best approach this? thanks. the main problem see delayed:job.work_off approach making explicit in cucumber scenarios belongs internals of system. mixing both concerns against spirit of functional testing: when click link # operation launched in background , jobs dispatched # delayed:job.work_off invoked here should see results... another problem populate cucumber scenarios repetitive steps dispatching jobs when needed. the approach using launching delayed_job in background while cucumber scenarios being executed . can check cucumber hooks using in link.

short version: can read dozens or hundreds of table partitions in multi-threaded manner increase performance orders of magnitude? long version: we're working on system storing millions of rows in azure table storage. partition data small partitions, each 1 containing 500 records, represents day worth of data unit. since azure doesn't have "sum" feature, pull year worth of data, either have use pre-caching, or sum data ourselves in azure web or worker role. assuming following: - reading partition doesn't affect performance of - reading partition has bottleneck based on network speed , server retrieval we can take guess if wanted sum lot of data on fly (1 year, 365 partitions), use massively parallel algorithm , scale number of threads. example, use .net parallel extensions 50+ threads , huge performance boost. we're working on setting experiments, wanted see if has been done before. since .net side idle waiting on high-latency operations, seems pe...
