java - Kafka Producer Request Timeout setting -


i set request time-out added request.timeout.ms parameter. bu when have broken instinctively broker connection there not timeout error occur?

what missing in configuration? need modify server setting well?

 public void init() {           logger.info("initializing  kafkaproducer: topic name: {}", topic);           system.out.println("initializing  kafkaproducer: topic name: {}");           properties properties = new properties();           properties.put("bootstrap.servers", brokerlist);           properties.put("key.serializer", "org.apache.kafka.common.serialization.stringserializer");           properties.put("value.serializer", "org.apache.kafka.common.serialization.stringserializer");           properties.put("acks", "1");           properties.put("retries", "3");           properties.put("linger.ms", 5);           properties.put("block.on.buffer.full", false);           properties.put("request.timeout.ms", "1000");           //properties.put("metadata.fetch.timeout.ms", 1000);              producer = new kafkaproducer<>(properties);        }           public void produce(string txnlogstr) {           producerrecord<string, string> record = new producerrecord<string, string>(topic, txnlogstr);           producer.send(record, new producercallback());            }         private class producercallback implements callback {           @override           public void oncompletion(recordmetadata recordmetadata, exception e) {               system.out.println("oncompletion recordmetadata:"+recordmetadata.offset()+", e:"+e);              if (e != null && recordmetadata != null) {                 logger.error("kafka queue problem. topic: {}", topic, e);                 e.printstacktrace();              }else {                  system.out.println("no error");              }           }        }

kafka version : kafka_2.11-0.10.2.0

pom.xml

 <dependencies>     <dependency>             <groupid>org.apache.kafka</groupid>             <artifactid>kafka_2.11</artifactid>             <version>0.10.2.0</version>                   </dependency>         <dependency>             <groupid>org.apache.kafka</groupid>             <artifactid>kafka-clients</artifactid>             <version>0.10.2.0</version>           </dependency>     </dependencies>

worked following property setting 

properties.put("metadata.fetch.timeout.ms", "1000");

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
