Transcript

1. Apache Titan • What is Titan ? • Graph Storage • Uses Tinkerpop • CAP Theorum • Architecture • Books www.semtech-solutions.co.nz info@semtech-solutions.co.nz
2. Titan – What is it ? • A Graph Database • Created by Aurelius, now owned by Datastax • Apache 2 license • Tinkerpop integration • Highly scaleable • Supports ACID • High performance • Datastax is developing DSE graph database – Influenced by Titan www.semtech-solutions.co.nz info@semtech-solutions.co.nz
3. Titan – Graph Storage • Titan storage backends – Apache HBase – Datastax Cassandra – Oracle Berkeley DB • Integrates with – ElasticSearch – Solr – Lucene www.semtech-solutions.co.nz info@semtech-solutions.co.nz
4. Titan – Tinkerpop • Titan 0.9.x uses Tinkerpop – Gremlin + Frames – Rexster + Blueprint • Has graph interaction via – OLTP – OLAP • GraphComputer vertex prog. • Gremlin server access by – Gremlin console – REST API – Java www.semtech-solutions.co.nz info@semtech-solutions.co.nz
5. Titan – CAP Theorum • CAP Theorum – C=Consistency – A=Availability – P=Partitionability • HBase favours consistency – At expense of yield – i.e. non completed requests • Cassandra favours availability – At expense of harvest – i.e. completeness of answer • Berkeley DB is non distributed www.semtech-solutions.co.nz info@semtech-solutions.co.nz
