Introduction

we liberate enterprise data

Whatis“Streaming”

• Theprocessingandanalysisofstructuredor“unstructured”datainreal-time

• WhyStreaming?• Whenspeed(velocity)ofdataiskey• Streamingdataisprocessedin“timewindows”,inmemory,acrossaclusterofservers

• Examples:• Calculatingaretailbuyingopportunity• Real-timecostcalculations• IoTdataanalysis

WhyOracleDataIntegration?

• EnterprisehasinvestedheavilyinODIand/orGoldenGate

• Gettingstartedwithdevelopmentlanguages(Python/pySpark,Java,etc)

• Centralizedmetadatamanagement• Integratewithotherdatasourcesusingasingleinterface

• Realizedcostsavings• AccordingtoGartner,200%increaseinmaintenancecostswhencustomcoding(https://www.gartner.com/doc/3432617/does-customcoded-data-integration-stack)

WhyGoldenGatewithKafka?

• Heterogeneoussourcesandtargets• Builttointegratealldata

• Flexibility• Reusablecodetemplates(KnowledgeModules)

• ReusableMappings• ODIcanadapttoyourdatawarehouse-andnottheotherwayaround

• Flowbasedmappings

• OnlysupportforCSV• FutureformatsmayincludeJSON,Avro,etc

• AddDatastoretomapping
