i trying log lambda function failures in such way event , context information saved event information can, if deemed necessary, later manually republished function's trigger. not want handle logic in functions themselves. what i've tried far: cloudwatch alarms on error metric. tell me function has failed. looking in cloudwatch logs. see coded failure messages emitted each function. there no such setting, if that's you're looking for. if you'd these properties logged, have print them - way visible in cloudwatch , whatever service logs piped (logs can piped elasticsearch example, cloudwatch ). however, can done adding these 2 lines of code: exports.handler = (event, context, callback) => { console.log(json.stringify(event)); console.log(json.stringify(context)); // code }; as rule of thumb, logs way describing lambda went through @ each invocation.

i'm testing nodejs app serves media files stored in memory. media files approximately 2mb-5mb each in size. i'm trying figure out what's best way max out available ethernet channel (1 gbps or 10 gbps). i'm testing in vm (virtualbox) ubuntu 16.04.1 lts. testing i'm using own nodejs script makes multiple outgoing requests server , logs console average bitrate. test nodejs script runs 1 minute , there configurable parameter n indicates how many simultaneous downloads can have @ once. what noticed if increase number of simultaneous downloads average throughput goes down considerably. example: if tun test n = 30 (30 simultaneous downloads) 125 mb/s overall, in case each of these requests served @ 3-5 mb/s now, if run n = 300 overall bitrate of 90 mb/s or 30% lower if run n = 600 overall bitrate of 80 mb/s. any idea why doesn't seem scale higher number of simultaneous downloads? higher number of simultaneous connections doesn't have cpu impact, i...

this question has answer here: is list<dog> subclass of list<animal>? why aren't java's generics implicitly polymorphic? 12 answers for historical reasons must use abstract class 2 wildcard parameters: abstractcolumn<m, i> and have implementation(idatasource interface): simplecolumn<i> extends abstractcolumn<idatasource<i>, i> the problem starts when should cast idatasource<i> parameter it's implementation, e.g. genericdatasource<i> : simplecolumn<i> column; abstractcolumn<genericdatasource<i>, <i>> newcolumn = (abstractcolumn<genericdatasource<i>, <i>>)column; i'm getting error: type mismatch: cannot convert abstractcolumn<genericdatasource<i>,i> abstractcolumn<idatasource<i>,i> and if i'm trying convert ida...
