20. Feature Highlights 20 © DataStax, All Rights Reserved.

21. DSE Graph – Customer Data Model Customer Name is a Property Vertex Edge 21 © DataStax, All Rights Reserved.

22. DSE Graph – Persistence | Adjacency List • Adjacency list storage optimized for graph database performance • Cassandra storage system optimized for availability and scale Consecutive, Sorted List Storage Vertex 1 Edge 1 Edge 2 Edge 3 Edge 4 Edge … 22 © DataStax, All Rights Reserved.

23. DSE Graph – Data Access | Traversals • Query Access => Apache TinkerPop Gremlin • Traversal style data navigation Find all orders purchased by Lisa g.V().has('customer', 'name', 'Lisa').out('ordered').values('number') Find all products purchased by Lisa’s Friends g.V().has('customer', 'name', 'Lisa') .outE('related').has('Type','friend').inV().out('ordered') .out('purchased').values('name’) Recommendation - find all products purchased by Lisa’s Friends, not purchased by Lisa g.V().has('customer', 'name', 'Lisa') .as('customer').out('ordered').out('purchased') .aggregate('products').in('purchased').in('ordered') .where(neq('customer')).out('ordered').out('purchased') .where(without('products')).values('name') 23 © DataStax, All Rights Reserved.

24. DSE Graph – Data Access | Global Indexes • DSE Graph has seamless integration with DSE Search • DSE Graph’s query optimizer automatically uses the right Index behind the scenes • Search workloads can be separated from OLTP workloads. • DSE Graph maintains the DSE Search core • Advanced users can configure the core directly • Three Options Available • DSE Search Integration • Cassandra 2is • Materialized Views • DSE Search Indexes Supports • Fuzzy and Phrase indexing for Text searching • Geospatial indexing/searching for Points, LineStrings, and Polygons 24 © DataStax, All Rights Reserved.

25. DSE Graph – Data Access | Analytics • DSE Graph has seamless integration with DSE Analytics • OLAP workloads can be separated from OLTP workloads. • Key OLAP Features: • Deep Traversals • Scan Traversals • Subgraph Snapshots – persisted RDDs • Counts • Two options for analytics • DSE Graph Frames • Gremlin OLAP • Both options leverage Spark but do so differently 25 © DataStax, All Rights Reserved.

26. DSE Graph – Data Access | DSE Drivers ● Recommended path is DSE Drivers ● All DSE Drivers support graph – Java, Python, C#, node.js, C/C++, Ruby, PHP ● Gremlin Fluent API – Starting with Java and Python ● Cluster aware ● Node health aware 26 © DataStax, All Rights Reserved.

27. DSE Graph – Security | Authentication & Authorization • Internal authentication and LDAP support • Kerberos authentication support • Object level permissions are at CQL table level • Future roadmap item for DSE Graph 27 © DataStax, All Rights Reserved.

28. DSE Graph – Security | Encryption • Client to node encryption with DSE Drivers • Node to node encryption • Transparent data encryption • Data auditing is available 28 © DataStax, All Rights Reserved.

29. DSE Graph – Data Ingestion | Graph Loader • Simplifies loading large amounts of data from various sources into DSE Graph efficiently and robustly • Inspects incoming data for schema compliance • Uses declarative data mappings and custom transformations to handle diverse types of data • Streamlined write path for custom vertex IDs (5.1) 29 © DataStax, All Rights Reserved.
