DataStax: What's New in Apache TinkerPop - the Graph Computing Framework
0 likes799 views
Apache TinkerPop is an open source graph computing framework, which centralizes around the Gremlin graph traversal language. It provides a number of libraries and utilities that help simplify the development of graph-related applications. Apache TinkerPop has always provided a vendor-agnostic way to work with different graph databases, like Titan and Neo4j, but now, under TinkerPop3, provides similar capabilities for scalable computation frameworks, like Hadoop and Spark. TinkerPop3 introduces many reinvented concepts from earlier versions of the TinkerPop stack and provides new capabilities that together will require those familiar with TinkerPop to adjust their thinking and those new to the ecosystem to be aware of the important features it presents. This talk will provide an overview of "what's new" in TinkerPop3 and provide detail on the Gremlin query language and supporting utilities, like Gremlin Console and Gremlin Server, which help support analysis and application development.
