20. Decisions, Decisions, Decisions • Unprecedented variety of data store choices to meet the needs of their varied workloads • Enterprises have many needs for databases, including cache, operational, data warehouse, master data, ERP, analytical, graph data, data lake, and time series data • While vendor offerings have exploded in recent years, in due time frameworks will integrate components into what amounts to a single offering for multiple workloads, perhaps even for the enterprise • But what if price-performant offerings for adjacent workloads in an enterprise have materialized? 5

21. Many Data Types • Web Crawlers • Open Linked Data • JSON • XML • Documents • Binary • Graph • Log Files 6

22. Why NoSQL for Operational Big Data More data model flexibility – Web Services as a data model – No !schema first" requirement; load first Faster time to insight from data acquisition Relaxed ACID – Eventual consistency – Willing to trade consistency for availability – ACID would crush things like storing clicks on Google Low upfront software and development costs Programmers love the freedoms Fault-tolerant redundancy Linear Scaling to “webscale” 7

23. • Placement policy: A copy is written to the node creating the file (write affinity) A second copy is written to a data node within the same rack (to minimize cross-rack network traffic) A third copy is written to a data node in a different rack (to tolerate switch failures) Node 5 Node 4 Node 3 Node 2 Node 1 Block 1 Block 3 Block 2 Block 1 Block 3 Block 2 Block 3 Block 2 Block 1 Objectives: load balancing, fast access, fault tolerance DFS Block Placement 8

CAR DRIVES name: “Dan” born: May 29, 1970 twitter: “@dan” name: “Ann” born: Dec 5, 1975 since: Jan 10, 2011 brand: “Volvo” model: “V70” Property Graph Model Components Nodes • The objects in the graph • Can have name-value properties • Can be labeled friends friends LIVES WITH O W N S PERSON PERSON Relationships • Relate nodes by type and direction • Can have name-value properties 9

25. Semantic Graph • RDF Triple Store – Semantic databases only work with RDF • Target market is users of third-party data in RDF (all Linked open data) – Working across data sets 10

26. Databases are Multi-Model when they can be either (for example): 11

27. Data Types and NoSQL Data Models Data Type Data Model CSV, TSV or web logs Column, Document Documents Document JSON Document Metadata catalog Column, Document Keyed images and documents Key-Value RDF, Linked data Graph 12

28. Key-Value Stores What are they? • NoSQL’s OLTP equivalent • Extremely simple • Key-”blob pairs”, that’s it • Associative array data model • Retrieve value given a key – All access is by a key (key,value) 13

29. Key-Value Stores Technical Characteristics: • Horizontally scalable • Fast (did I mention fast) • Resiliency to cluster failures • Simplicity • All nodes equal 14 (key,value)

30. Key-Value Stores Good for: • Any single object of unstructured data • Storing BLOBs • Fast writes • Web app cache • Session Information – get all session information in a single put/get • User profile data • Massive multi-player on-line gaming • Shopping carts (up until the payment transaction) • Geo-localized processing • Speed when you can’t be down (key,value) 15

31. A multi-model database is a single, integrated database that can store, manage and query data i multiple models such as relational, document, graph, key-value, column-store, cache. It is the opposite approach to Polyglot Persistence – the use of multiple databases in a workload. 16

32. Document-oriented Databases What are they? • Key-Value Stores with added capabilities – Ability to nest sub-documents • JSON/XML data models • With Tree-Like Structure • Encapsulated document objects • Groups data together more naturally and logically 17

33. Document-oriented Databases Technical Characteristics: • Store all data together – Example: Order document contains all line items • Documents are self-describing hierarchical tree structures • Unlike Key-Value Stores, the value part of the field can be queried 18

34. Document-oriented Databases Good for: • Semi-structured data • Web pages • Web traffic/E-Commerce • Web analytics • Log files • User actions/behaviors • Content Management Systems • Full text • Uncertain data • Extending object-oriented approaches • Event logging • JSON/XML data 19

35. Document Example { "type": "BakingRecipe", "name": "Mama’s Cornbread", "ingredients": [ { "name": "cornmeal", "amount": ”1c" }, { "name": "flour", "amount": "3/4c" }, { "name": "baking powder", "amount": "1-1/2t" }, { "name": "eggs", "amount": "2 large" }, { "name": ”butter", "amount": "6T" }, { "name": "buttermilk", "amount": "1-1/2c”, “brand”: “ABC Brand”} ], ”ovenTemperature": ”425 deg F" ”bakeTime": ”20 min” } 20

36. Multiple NoSQL Solutions Working Together You could use • Key-Value Store for Shopping Cart and Session Data • Document or Column Store for Consuming Completed Orders • RDBMS for inventory (small, not served real- time), financials • Graph Store for Customer Relationships for Marketing 21

37. Column Stores What are they? • Data model: – A big table, with column families – Map-reduce for querying/processing • Schema-lite • No single point of failure • Operational simplicity • Closest NoSQL implementation to RDBMS 22

38. Column Stores Good for: • Large amounts of data • Data that needs compression • Event logging • Content Management Systems • Data model supports semi-structured data • Naturally indexed (columns) • Good at scaling out horizontally • Time Series data – Weather data – Location data – Sensor data 23

39. Column Stores Example 24

40. What to Look for in Multi-Model 1/2 • Excellent implementation of multiple models • Single copy of data • Model change propagation • Works in microservices world • Submillisecond response time 25

41. What to Look for in Multi-Model 2/2 • Globally distributed multi-region deployments • Cross-model data processing language and optimizer • Edge-capable database • JSON flattening without data explosion • Universal indices 26

42. Emerging Technologies • Use of artificial intelligence (AI) • Integration with data catalog platforms • Robust user experience • Multi-cloud/native application 27
