Gremlin, the graph traversal language from Apache TinkerPop, continues to evolve in support of the growing graph ecosystem. In this session, we'll take a deep dive into Gremlin Language Variants (GLV) to see how TinkerPop enables modern programming languages to leverage Gremlin natively. By converting Gremlin into bytecode, the same instructions can be transmitted and interpreted by graph systems from different vendors. We'll uncover the benefits of this approach by demonstrating a Python-based graph architecture built to empower your application developers and data scientists. By using popular packages from Python open source, like Flask microframework and Jupyter notebooks, we'll see how you can easily transition your app development from your machine to the IBM Cloud. Presented at Graph Day SF on June 17, 2017.

JanusGraph: Looking Backward and Reaching Forward - by Jason Plurad (@pluradj): The JanusGraph project started at the Linux Foundation earlier this year, but it is not the new kid on the block. We'll start with a look at the origins and evolution of this open source graph database through the lens of a few IBM graph use cases. We'll discuss the new features in latest release of JanusGraph, and then take a look at future directions to explore together with the open community.

Graphs are everywhere, but in a modern data stack, they are not the only tool in the toolbox. With Apache TinkerPop, adding graph capability on top of your existing data platform is not as daunting as it sounds. We will do a deep dive on writing Traversal Strategies to optimize performance of the underlying graph database. We will investigate how various TinkerPop systems offer unique possibilities in a multimodel approach to graph processing. We will discuss how using Gremlin frees you from vendor lock-in and enables you to swap out your graph database as your requirements evolve.

Jason Plurad

Graphs are well-suited for many use cases to express and process complex relationships among entities in enterprise and social contexts. Fueled by the growing interest in graphs, there are various graph databases and processing systems that dot the graph landscape. JanusGraph is a community-driven project that continues the legacy of Titan, a pioneer of open source graph databases. JanusGraph is a scalable graph database optimized for large scale transactional and analytical graph processing. In the session, we will introduce JanusGraph, which features full integration with the Apache TinkerPop graph stack. We will discuss JanusGraph's optimized storage model that relies on HBase for fast graph transversal and processing. Presented with Jing Chen (Jerry) He at HBaseCon West 2017, June 12, 2017.

Graphs are growing in popularity, but the landscape is becoming a hairball. Learn how to unravel it with the Apache TinkerPop graph computing framework and Gremlin, a functional, data flow language for traversing graphs. This session helps you distinguish between OLTP and OLAP graph processing as well as how to bridge the gap between graph databases and graph engines. We will offer TinkerPop alternatives for effective graph processing that go beyond Spark GraphX. We will also cover how to spin up a graph development environment quickly with Apache Ambari. Presented May 11, 2016 at Apache: Big Data 2016 conference. http://sched.co/6M2y

We've all been there before... you hear the announcement that your flight is canceled. Fellow passengers race to the gate agent to rebook on the next available flight. How do they quickly determine the best route from Berlin to San Francisco? Ultimately the flight route network is best solved as a graph problem. We will discuss our lessons learned from working with a major airline to solve this problem using JanusGraph database. JanusGraph is an open source graph database designed for massive scale. It is compatible with several pieces of the open source big data stack: Apache TinkerPop (graph computing framework), HBase, Cassandra, and Solr. We will go into depth about our approach to benchmarking graph performance and discuss the utilities we developed. We will share our comparison results for evaluating which storage backend use with JanusGraph. Whether you are productizing a new database or you are a frustrated traveler, a fast resolution is needed to satisfy everybody involved.

Big Data, a recent phenomenon. Everyone talks about it, but do you really know what Big Data is? Join our four-part series about Big Data and you will get answers to your questions! We will cover Introduction to Big Data and available platforms which we can use to deal with Big Data. And in the end, we are going to give you an insight into the possible future of dealing with Big Data. After the two previous episodes you know the basics about Big Data. Yet, it might get a bit more complicated than that. Usually when you have to deal with data which is generated in real-time. In this case, you are dealing with Big Stream. This episode of our series will be focussed on processing systems capable of dealing with Big Streams. But analysing data lacking graphical representation will not be very convenient for us. And this is where we have to use a platform capable of visualising Big Graphs. All these topics will be covered in today’s presentation. #CHEDTEB www.chedteb.eu

Computer systems architecture evolve in cycles every 15-20 years, oscillating between centralization and decentralization: centralized mainframes of the 60s, decentralized PCs of the 80s, centralized web apps of the 90s. Since 2010, we see a new architecture shift back to the 80's client-server model, with 3 trends: powerful mobile device (android, iphone), the browser becoming a rich client platform with html5, and cloud platforms commoditizing distributed computing on the server. This talk is about the server side of the current architecture shift. As most technology architecture changes, cloud computing adoption is driven by factors from multiple dimensions, not only technical ones: - technology: Big Data & fast networks, shift from vertical to horizontal scalability, commoditization of distributed computing (Virtualization, Sharding, Storage, NoSQL databases, Paxos, Map/Reduce, Go language), centralization of security - economy: broadband and wireless ubiquity, shift from product to services, economies of scale, Moore's law, cost of electricity becoming main driver for computing cost , pay as you go models - culture: consumerization of enterprise technology, technology achieves ubiquity by disappearing 20 years ago when I was involved with Command and Control Systems for the french DoD, they were called C3I. Since then it seems they added a C for Computers, C4I. Maybe for the next 20 years the 4th C of C4I should stand for Cloud.

We perform this come-to-me love spell that works instantly with the aim of bringing back the victim to the person performing the magic. Have you lost your lover? Do u need to solve any relationship problem? Contact the powerful spells caster chief kule with love spells that work overnight and love spells that really work. Have you found yourself infatuated with a special someone you think could be the one? Are you looking for a spell to provide them with a nudge in the right direction? Or maybe the spell you cast didn’t achieve the results you were hoping for? Whether you’re new or versed in the ways of spell casting, we’re here to help. Today we’re going to provide you with a detailed guide on the types of love spells to cast. Not only that but there’s something for those who wish to find outside advice from more advanced spell casters. We’re also going to provide you with the top sites available to help you with your dilemma. Let’s begin our journey by educating ourselves on love magic and what a real love caster looks like. Love Magic and Love Casters Love magic made its first appearance back in Ancient Egypt and has been an active practice since. This type of magic is a branch of traditional magic and can be practiced in various ways. Typically the more common use of love magic is through the work of spells, but other methods look like Charms Rituals-LOVE Potions-Dolls and even Amulets If you are interested in becoming a love caster, be prepared for what’s to come. A genuine love caster knows that the art of love casting is no easy feat and shouldn’t be done casually. You should know that not only does it require you to be gifted spiritually, but you must be ready to serve others. Someone who is considered a real love caster has experience in all manner of spells, no matter the difficulty. Training yourself in attraction, commitment, and marriage spells is an excellent place to start. But this by no means will make you a professional. Practice your craft and expand your knowledge; understand that you will possess the ability to help others in time truly. Types of Love Spells What better way to start broadening your experiences with love spells than by learning more about them? These spells work like just about any other spell. Simply apply your intention, use a medium (sigils, mantras, candles, or charm bags), and top it off with establishing the belief that you will receive what you want. So what kind of spells are available and which ones suit your needs the best? Let’s take a look at the many options you have at your disposal

WSO2

Data spaces in distributed environments should be allowed to evolve in agile ways providing data space owners with large flexibility about which data they store. Agility and heterogeneity, however, jeopardize data exchanges because representations may build on varying ontologies and data consumers may not rely on the semantic correctness of their queries in the context of semantically heterogeneous, evolving data spaces. Graph data spaces are one example of a powerful model for representing and querying data whose semantics may change over time. To assert and enforce conditions on individual graph data spaces, shape languages (e.g SHACL) have been developed. We investigate the question of how querying and programming can be guarded by reasoning over SHACL constraints in a distributed setting and we sketch a picture of how a future landscape based on semantically heterogeneous data spaces might look like.
