  • In Storm bolts shuffle group based on regions so that each HBase bolt gets data mostly for one or two regions and minimizes RS trips

    In case of DoS attack situations where actual packet are very small 20-60 bytes and individual packets are not very critical for analysis, skip WAL

  • 19. 19 Applications: Telemetry Matching and DPI Step1: Search Step2: Match Step3: Analyze Step4: Build PCAP
  • 20. 20 Integration with Analytics Tools Dashboards Reports
  • 21. 21 Best Practices and Lessons Learned
  • 22. 22 Journey Towards Highly Scalable Application
  • 23. 23 Kafka Tuning
  • 24. 24 This is where we began
  • 25. 25 Some code optimizations and increased parallelism
  • 26. 26  Is Disk I/O heavy  Kafka 0.8+ supports replication and JBOD  Better performance compared to RAID  Parallelism is largely driven by number of disks and partitions per topic  Key configuration parameters:  num.io.threads - Keep it at least equal to number of disks provided to Kafka  num.network.threads - adjust it based on number of concurrent producers, consumers and replication factor Kafka Tuning
  • 27. 27 After Kafka Tuning
  • 28. 28 Bottleneck Isolation, Resource Profiling, Load Balancing
  • 29. 29 HBase Tuning
  • 30. 30 This is where we began
  • 31. 31  Row Key design is critical (gets or scans or both?)  Keys with IP Addresses  Standard IP addresses have only two variations of the first character : 1 & 2  Minimum key length will be 7 characters and max 15 with a typical average of 12  Subnet range scans become difficult – range of 90 to 220 excludes 112  IP converted to hex (10.20.30.40 => 0a141e28)  gives 16 variations of first key character  consistently 8 character key  Easy to search for subnet ranges Row Key Design
  • 32. 32 Experiments with Row Key
  • 33. 33  Know your data  Auto split under high workload can result into hotspots and split storms  Understand your data and presplit the regions  Identify how many regions a RS can have to perform optimally. Use the formula below (RS memory)*(total memstore fraction)/((memstore size)*(# column families)) Region Splits
  • 34. 34 With Region Pre-Splits
  • 35. 35  Enable Micro Batching (client side buffer)  Smart shuffle/grouping in storm  Understand your data and situationally exploit various WAL options  Watch for many minor compactions  For heavy ‘write’ workload Increase hbase.hstore.blockingStoreFiles (we used 200) Know Your Application
  • 36. 36 And Finally
  • 37. 37 Kafka Spout
  • 38. 38  Parallelism is controlled by number of partitions per topic  Set Kafka spout parallelism equal to number of partitions in topic  Other key parameters that drive performance  fetchSizeBytes  bufferSizeBytes Kafka Spout
  • 39. 39 Mysteriously Missing Data
  • 40. 40  A bug in Kafka spout that used to miss out some partitions and loose data  It is now fixed and available from Hortonworks repository ( http://repo.hortonworks.com/content/repositories/releases/org/apache/ storm/storm-Kafka ) Mysteriously Missing Data Root Cause
  • 41. 41 Storm
  • 42. 42  Every small thing counts at scale  Even simple string operations can slowdown throughput when executed on millions of Tuples Storm
  • 43. 43  Error handling is critical  Poorly handled errors can lead to topology failure and eventually loss of data (or data duplication) Storm
  • 44. 44  Tune & Scale individual spout and bolts before performance testing/tuning entire topology  Write your own simple data generator spouts and no-op bolts  Making as many things configurable as possible helps a lot Storm
  • 45. 45  When it comes to Hadoop…partner up  Separate the hype from the opportunity  Start small then scale up  Design Iteratively  It doesn’t work unless you have proven it at scale  Keep an eye on ROI Lessons Learned
  • 46. 46 How can you contribute?  Technology Partner Program – contribute developers to join the Cisco and Hortonworks team Looking for Community Partners Cisco + Hortonworks + Community Support for OpenSOC
