Troubleshooting bottleneck in simple azure function


hi guys,

i have simple azure function accepting webhook , immediately

writes 2 storage queues (code below).

today triggered made webhook called approximately few hundred times on a short period of time (i'm guessing invoked 1.500 times in loop external service).

the first dozen calls went through fine runtime seemed hang , after restarting couple of times seems function calls retried in bursts , succeeded. checking monitoring saw dozens of functions hanging (...) on 80 seconds.

the function app runs on basic plan , didn't see peaks in cpu or memory in time period.

i want understand better why runtime behaves , how can diagnose these issues , potentially remove bottlenecks before scaling up. seems me kind of work (only io bound, using node , azure storage , fn bindings) should perfect fit azure functions , should run performance problems already.

any apprecheated.

module.exports = function (context, data) {
context.bindings.queue1= [{
partitionkey: 'ax',
rowkey: data.event + "-" + date.now(),
value: 1.0

}];

context.bindings.queue2 = [{ action: 'event', name: data.event }];

context.done();
}


can share function app name either directly or indirectly (https://github.com/azure/azure-webjobs-sdk-script/wiki/sharing-your-function-app-name-privately) , i'll take look

C# System.Data.Common DbCommand and getting Datasets from Oracle

i found no oracle specific forum area, decided post here. getting dataset oracle c# system.data.common library's dbcommand seems tricky task. i using command object in project along dbproviderfactory , dbdataadapter because meant allow use same library multiple database providers, , don't have clutter data access layer of project separate classes accessing each individual database provider. my problem is, stored procedures fetching data oracle require refcursor object added in parameters. however, dbtype library not contain definition object. using "object"-type not work. i have read many places not have add refcursor parameter, endless failed attempts @ running command without refcursor object has brought me conclusion leaving out refcursor object not option when using system.data.common library. here coded example connectionstring purposefully left out.                 dbconnection.ope...
