The core Search frameworks in Liferay 7 have been significantly retooled to benefit not only from Liferay's new modular architecture, but also from one of the most innovative players in the market: Elasticsearch, which replaces Lucene as the default search engine in Portal. This session will cover topics like clustering and scalability, unveil improvements (both Elasticsearch and Solr) like aggregations, filters, geolocation, "more like this" and other new query types, and also hot new features for the Enterprise like out-of-the-box Marvel cluster monitoring and Shield security.
André "Arbo" Oliveira joined Liferay in early 2014 as a senior engineer and leads the Search Infrastructure team. He's been writing code for a living for 22 years, 14 of them as a Java developer and architect. Ever since discovering Elasticsearch, he's vowed never to write another SQL WHERE clause again.

Liferay makes it easy to integrate your application with powerful search engines. However, it may be hard to diagnose why your most important content isn't showing up the way you need it to. This session will recap the key concepts for indexing and querying with Liferay Search, and present a number of techniques to guarantee your documents will be found with best possible relevance.
André de Oliveira joined Liferay in early 2014 as a senior engineer and leads the Search Infrastructure team. He's been a Java developer and architect for the last 15 years. Ever since discovering Elasticsearch, he's vowed never to write another SQL WHERE clause again.
A brief introduction to Elasticsearch and the many possibilities Elasticsearch offers in terms of search, data exploration and data aggregation. The presentation includes a brief introduction to search engine fundamentals and core features of Elasticsearch. The talk focuses on how we can navigate structured and unstructured data for search as well as aggregating and visualizing data for analytical purposes.
The talk aims to demonstrate case studies beyond traditional full-text-search, and hopefully show that Elasticsearch can help us build so much more than just a search engine.

Webinar: Strongly Typed Languages and Flexible SchemasMongoDB
Strong statically typed languages are safer because they capture programmer intent. Dynamic schemas are flexible and allow for rapid development. Having both at the same time, on the same system is a great way to build an easy to iterate, modularized and flexible application, but these properties can also generate some friction. There are a set of rules and best practices around schema versions and data type validations that are crucial to make this symbiotic system work properly.
Over the course of this webinar we will show you techniques and mechanisms to use when modeling your system with MongoDB. We will review schema design best practices and real world examples that deal with these complex topics.
We will focus on making sure you understand the benefits and performance gains of using both strongly statically typed languages along with dynamic and flexible schema database like MongoDB.

Closing the Loop in Extended Reality with Kafka Streams and Machine Learning ...confluent
We’ve built a real-time streaming platform that enables prediction based on user behavior, with events occurring in virtual and augmented reality environments. The solution enables organizations to train people in an extended reality environment, where real-life training may be costly and dangerous. Kafka Streams enables analyzing spatial and event data to detect gestural feature and analyze user behavior in real-time to be able to predict any future mistake the user might make. Kafka is the backbone of our real-time analytics and extended reality communication platform with our cluster and applications being deployed on Kubernetes.
In this talk, we will mainly focus on the following: 1. Why Extended Reality with Kafka is a step in the right direction. 2. Architecture & Power of Schema Registry in building a generic platform for pluggable XR apps and analytics models 3. How KSQL and Kafka Streams fits in Kafka Ecosystem to help analyze human motion data and detect features for real-time prediction. 4. Demo of a VR application with real-time analytics feedback, which assists people to be trained in how to work with chemical laboratory equipment.
Strongly Typed Languages and Flexible SchemasNorberto Leite

Leveraging Lucene/Solr as a Knowledge Graph and Intent EngineTrey Grainger
Search engines frequently miss the mark when it comes to understanding user intent. This talk will describe how to overcome this by leveraging Lucene/Solr to power a knowledge graph that can extract phrases, understand and weight the semantic relationships between those phrases and known entities, and expand the query to include those additional conceptual relationships. For example, if a user types in (Senior Java Developer Portland, OR Hadoop), you or I know that the term “senior” designates an experience level, that “java developer” is a job title related to “software engineering”, that “portland, or” is a city with a specific geographical boundary, and that “hadoop” is a technology related to terms like “hbase”, “hive”, and “map/reduce”. Out of the box, however, most search engines just parse this query as text:((senior AND java AND developer AND portland) OR (hadoop)), which is not at all what the user intended. We will discuss how to train the search engine to parse the query into this intended understanding, and how to reflect this understanding to the end user to provide an insightful, augmented search experience. Topics: Semantic Search, Finite State Transducers, Probabilistic Parsing, Bayes Theorem, Augmented Search, Recommendations, NLP, Knowledge Graphs

"Secure Your Premises with VizMan (VMS) – Get It Now"
In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.
Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?
