  4. 4   Elastic @ GS Grass Roots Usage of Open

    Source n Developer  driven  culture  that  promotes  the  use  of  open  source   n Significant  usage  by  late  2014:  700+  nodes   n Centralized  Elas(csearch  engineering  team  formed  mid  2014   n Diverse  use  cases   –  Search:  workflow  search,  trade  /  order  search  …   –  Document  Search:  legal  documents,  candidate  resume,  source  code   –  Metrics:  JVM,  Network,  App  Usage,  Alerts,  Transac(on  volumes  …   –  Making  Real  (me  transac(on  data  queryable   –  Data  Analy(cs  :  Order  Flow  Dashboards,  Analysis      
  5. 5   Center of Excellency Model Standardized Software Packaging n Internally

     build  open  source  code  from  GitHub   n Enhanced  with  GS  Plugins  for  Security  and  Backup   n Include  other  open  source  plugins  and  tools    
  6. 6   Center of Excellency Model Support n Elas(csearch  install  Inventory

      n Centralized  monitoring  and  metrics   n Governance  on  proper  usage   n Elas(c  Vendor  Support     –  Global  support   –  Design  review   –  Performance  tuning   –  Patching   n Integra(on  with  internal  code  base  using  custom  language  wrappers    
  7. 7   Equities Engineering Use Cases High Performance Order Search

    (Problem) n  Currently  order  transac(on  data  is  persisted  into  Sybase  databases   n  The  total  transac(onal  volume  is  so  large  that  DB  instances  need  to  be  split  into  many   stripes   n  Longer  (me  range  and  aggregated  queries  very  difficult  and  slow  -­‐  hours  in  some  cases.   n  Which  means  extrac(ng  meaningful  analy(cs  from  the  data  is  difficult   n  Different  sources  for  Historical  and  Real  Time  data  means  no  code  sharing      
  8. 8   Equities Engineering Use Cases High Performance Order Search

    (Solution)     n Extract  de-­‐normalized  views  of  Historical  data  into  Elas(csearch   n Intra-­‐day  data  indexed  from  live  transac(on  feed   n Unified  schema  –  querying  historic  and  live  data  from  a  single   source   n U(lize  ES  Aggrega(ons  for  fast  analy(c  queries      
  9. 9   Equities Engineering Use Cases Management Analytics – Sharp-X

    n High  level  dashboard  showing  per-­‐market  analysis  of  Order  Flow  data   n Replaced  and  greatly  expanded  upon  a  legacy  equivalent   n Aggregated  queries  across  both  Historical  and  live  upda(ng  data   n Ability  to  query  the  latest  transac(on  state  cri(cal   n Previous  Implementa(ons  relied  on  real  (me  transac(on  callbacks  to  perform  the   aggrega(ons.  Lots  of  custom  code   n U(lizing  the  Real  (me  feed  to  ES  and  aggrega(ons  for  querying  resulted  in  a   dras(cally  simplified  architecture  and  code  base

    steps n Ease  of  deployment  and  horizontal  scaling  are  game  changers   n Moving  from  the  Rela(onal  mental  model  takes  some  adjustment.  To  noSql  and  a   completely  new  query  language.   n Living  without  easy  joining  means  thinking  more  about  the  data  model  up  front   n Working  with  a  fast  moving  technology  comes  with  risks  and  challenges   n Elas(c’s  auto-­‐schema  feature  is  useful  for  development  but  can  cause  problems  in  a   produc(on  system.   n Indexes  are  low  cost  and  easy  to  re-­‐create.  Types  can't  be  easily  re-­‐created  without   re-­‐crea(ng  the  index   n Expanded  use  Of  Elas(csearch  in  other  problem  domains   n Plans  to  replace  the  rela(onal  data  sources  with  Hadoop.  Retaining  Elas(csearch  as   the  high  speed  query  engine  on  top.
