  14. Overview GitHub Investigate (As of December 2019)

  15. Overview “Slack's Vitess introduction was due to the very rapidly

    changing business needs and a system that was flexible enough to accommodate those changes.” “Slack currently has a goal of about 35% migration to Vitess and 100% next year.”
  16. Overview “JD.com is China's largest online shopping site. China's Black

    Friday sale has achieved a huge scale of about 4,000 key spaces, over 30,000 pods, and a QPS of 35 million (peak).”

    Complexity is born.” “You want these DB pods to be able to securely communicate for DB sharding & replication.
  22. Overview NSM-driven DB sharding & replication enables comprehensive, efficient communication,

    security and observability.
  23. What’s Vitess

  24. What’s Vitess

  25. What’s Vitess A cloud-native database cluster system that achieves high

    availability and scale on a large scale with Sharding MySQL
  26. What’s Vitess Architecture

  27. What’s Vitess Vitess on Kubernetes

  28. What’s Vitess vtgate A proxy server that routes queries from

    application to vttablet and returns the results to the client tablet mysqld and vttablet set vttablet Proxy server placed in front of MySQL (mysqld), also serves to protect MySQL from query rewriting, deduplication, and harmful queries vtctld HTTP server that serves as the window for management operations (GUI) of Vitess cluster vtctl Command line tool for managing Vitess cluster (CLI) Topology Metadata store that manages configuration information of Vitess cluster, Kubernetes supports etcd, and other than etcd supports ZooKeeper Technical Terms
  29. What’s Vitess Sharding • Store data divided into two or

    more databases • Scale-out and performance improvement by adding Shard Sharding of Vitess • Vertical Sharding Store in multiple databases for each table • Horizontal Sharding Divide one table into multiple shards and store them in multiple databases
  30. What’s Vitess Table Sharding VSchema is Sharding definition, routing information

    Refer to VTworkerVSchema and execute Sharding split processing Refer to VSchema and route to the appropriate Shard Keyspace is a logical database that combines multiple shards. Recognized as one database from application.
  31. What’s Vitess Reference Docs • Vitess is a database clustering

    system for horizontal scaling of MySQL https://vitess.io/ • Vitess Twitter https://twitter.com/vitessio • CrashAcademy 「CNDJP 勉強会 #8 Vitessのパフォーマンスと運用性を検証してみた」 https://crash.academy/ng/video/412/1736 • Vitess Slack https://vitess.slack.com/ • Vitess Github https://github.com/vitessio/vitess
  32. Case Studies & Maintainer Track & Storage Sessions

  33. Case Study Slack

  34. Case Studies & Maintainer Track & Storage Sessions In this

    talk, Rafael and Guido will share an overview about how Slack designed, built, scaled and then iterated to improve its distributed database service based on top of Vitess, now a CNCF project. The Databases team at Slack scaled a Vitess cluster from 0 to spikes of 2.7 Million queries per second. This journey has taught us how to operate a database cluster with more than 2000 nodes and expecting to growth to more than 3500 in the next 12 months.
  35. Case Studies & Maintainer Track & Storage Sessions

  36. Case Studies & Maintainer Track & Storage Sessions

  37. Case Studies & Maintainer Track & Storage Sessions 1.Databases at

    Slack Current status Legacy Shards Vitess Shards In progress migration of our entire dataset to Vitess.
  38. Case Studies & Maintainer Track & Storage Sessions Legacy Shards

    Vitess Shards Application level team-sharded active master-master MySQL setup. Master-replica MySQL setup fully managed by Vitess.
  39. Case Studies & Maintainer Track & Storage Sessions Why are

    we migrating? • “Migrating to Vitess at (Slack) Scale” - Mike Demmer (https://www.percona.com/live/18/sessions/migrating-to-vitess-at-slack-scale) • “Designing and launching the next-generation database system at Slack: from whiteboard to production” - Guido Iaquinti (https://www.percona.com/live/18/sessions/designing-and-launching-the-next-generation-database-system-slack-from-whiteboard-to-production) • “Smooth scaling: Slack’s journey toward a new database” - Ameet Kotian (https://conferences.oreilly.com/velocity/vl-ny/public/schedule/detail/69885) For more details please see the presentations on the slide.
  40. Case Studies & Maintainer Track & Storage Sessions tl;dr; shard

    size limits, inefficient resource distribution, operational overhead, single sharding model “While Slack users are on the rise, they are unable to scale quickly and flexibly and cannot meet business needs.” Why are we migrating?
  41. Case Studies & Maintainer Track & Storage Sessions • Scaling

    and sharding flexibility without changing SQL (much) • MySQL core maintains operator and developer know-how • Proven at scale at YouTube and more recently others • Active developer community and approachable code base Why Vitess?
  42. Case Studies & Maintainer Track & Storage Sessions Stats •

    Queries per day: 53+ billion • Storage provisioned: 7.5+ PB • Served by legacy infrastructure: ~60% • Served by Vitess: ~40% • Target: 70% served by Vitess by EOY Aim to complete the transition to Vitess within 2020 !!
  43. Case Studies & Maintainer Track & Storage Sessions

  44. Case Studies & Maintainer Track & Storage Sessions 2.Running databases

    in the cloud Immutable infrastructure Instance failure Durability through replication
  45. Case Studies & Maintainer Track & Storage Sessions How we

    run Vitess EC2 Percona MySQL5.7 ASG for stateless components Ephemeral NVMe (no EBS)
  46. Case Studies & Maintainer Track & Storage Sessions Not Kubernetes

  47. Case Studies & Maintainer Track & Storage Sessions

  48. Case Studies & Maintainer Track & Storage Sessions 3.Fault tolerance

    & isolation Slack cloud infrastructure • Amazon EC2 is hosted in multiple locations world-wide. • These locations are composed of Regions and Availability Zones (AZ’s). • Each Region is a separate geographic area. • AZ’s in a Region are connected through low-latency links.
  49. Case Studies & Maintainer Track & Storage Sessions Vitess initial

    deployment • A single cell across multiple AZ’s (fundamental). • Global and local topology using the same Consul cluster (circumstantial). Topology : Vitess Key-Value Store Consul : Service Discovery
  50. Case Studies & Maintainer Track & Storage Sessions

  51. Case Studies & Maintainer Track & Storage Sessions Resilient systems

    • Minimize the blast radius. • Isolation is key. • Understand your dependencies.
  52. Case Studies & Maintainer Track & Storage Sessions Current deployment

    • Isolated topologies (one dc for each AZ and one for the global topo). • Blast radius is mapped to physical infrastructure.
  53. Case Studies & Maintainer Track & Storage Sessions We have

    benefited already • AZ failure during backup time. • Single cell was affected!
  54. Case Studies & Maintainer Track & Storage Sessions Performance wins

  55. Case Studies & Maintainer Track & Storage Sessions

  56. Case Studies & Maintainer Track & Storage Sessions 4.Key Lessons

    Complex system failures • Complex systems are intrinsically dangerous systems. • Complex systems are heavily and successfully defended against failure. • Catastrophe is always just around the corner. • Complex systems contain changing mixtures of failures latent within them. How Complex Systems Fail – MIT (https://web.mit.edu/2.75/resources/random/How%20Complex%20Systems%20Fail.pdf)
  57. Case Studies & Maintainer Track & Storage Sessions Complex system

    failures Humility towards complexity. Reach out to other fields and learn from their experience.
  58. Case Studies & Maintainer Track & Storage Sessions

  59. Case Study Nozzle

  60. Case Studies & Maintainer Track & Storage Sessions Gone in

    60 Minutes: Migrating 20 TB from AKS to GKE in an Hour with Vitess - Derek Perkins, Nozzle • The holy grail of Cloud Native tech is to have zero vendor lock-in • migrate a high throughput production workload of 20 TB from Azure (AKS) to Google (GKE) in under an hour
  61. Case Studies & Maintainer Track & Storage Sessions Vendor lock-in

    is preferably zero, but there are good cases. But right judgment is important.
