apache kafka - MirrorMaker Cross DC Deployment Setup -

-

i have question regarding mirrormaker. see in official documentation (see https://cwiki.apache.org/confluence/pages/viewpage.action?pageid=27846330), mirrormaker placed on destination data center. there reason why can't placed on source data center instead?

i'm asking because in our current setup, mirrormaker placed on destination data center , seeing owning partitions on startup or rebalance takes long time.

our setup so:

  • 6 total kafka clusters across 4 data centers
  • each data centers has local kafka cluster
  • 2 aggregate kafka clusters in 2 of data centers
  • 400+ topics in each local kafka cluster
  • 2 groups of mirrormakers on same data center respective destination aggregate kafka clusters consumes 4 local kafka clusters
  • mirrormaker instances configured pull 400+ topics with catch regex 4 local kafka clusters aggregate clusters
  • our kafka versions 0.8.2.1 offsets stored in zookeeper

our issue on mirrormaker restart / consumer-rebalance partition ownership takes on 30+ mins when consuming local kafkas in different data centers.

my guess partition ownership process has go across data centers source kafka zookeepers, , cross dc connections slowing down mirrormaker partition ownership process.

i thinking of moving mirrormaker source data center instead, speed partition ownership on startup / rebalance. wondering if has tried setup , if there issues approach?

the mirror maker used high level consumer consume source cluster. default mirror maker takes time while re-balancing. not own problem. see uber struck mirror maker , how overcome ureplicator (https://eng.uber.com/ureplicator/). hope helps

i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response...
