i have json has id want insert mongo db. json {"id" : 538748, "event_date":"2016-07-02", "name" : "tim"} is there way map "id" mongo's _id when inserting? router.get('/newpage', function (req, res) { var db = req.db; var collection = db.get('mydatabase'); request({ url: "http://someurl.com/json", json: true }, function (error, response, body) { if (!error && response.statuscode === 200) { // how specify _id here collection.insert(body); } }); }); you need modify body doc you're inserting rename id field _id : body._id = body.id; delete body.id; collection.insert(body); but it's typically cleaner , safer build new doc valid fields, performing mapping in process: var doc = { _id: body.id, event_date: body.event_date, name: body.name }; collection.insert(doc);

multithreading - Does SAS have a concurrency framework like Java -

in java,you have concurrency framework developer can use submit multiple tasks in parallel each task runs in own thread. does similar concurrency framework exist in sas developer can submit parallel jobs or programs in different threads? with sas, there (as there are) myriad ways ask. the closest thing ask sas mp connect , system allowing multiple threads either on smp ( symmetric multiprocessing ) machine. it's part of sas/connect starting in version 8. if submitting code (via sas/connect) server, have other options. can submit multiple queries rsubmit using either synchronous or asynchronous processing, example. you can also, of course, submit multiple sas calls yourself, if don't have license sas/connect. can either have batch process calls multiple sas sessions different input parameters, or have sas call more copies of (recursively, perhaps). if have sas 9.4, can use proc ds2 , has built-in multithreading. more object-oriented approach sas data

persistence - Mesos & persistent storage using MySQL -

this going generic question. we young startup faced inevitable problem of scaling , during our research, apache mesos seemed fit our architecture, – core scala based microservices, each responsible dealing part of our database, mysql middleware microservices, deal other persistent data-storage systems mongodb, elasticsearch etc. which means can containerise of our services , ship them single datacenter can deploy these containers in topographically agnostic way. what stumped – mesos doesn't seem have native support mysql container based persistence seems awfully tricky , hard manage/maintain. we'd continue using mysql/mongodb/elasticsearch because migrating cassandra etc. @ stage (we small team) of overhead , hence not option. best strategies problem? mesos provide persistent resources support storage-like services . if want use mysql on mesos, please consider try https://github.com/apache/incubator-cotton
