A comparison of different solutions for full-text search in web applications using PostgreSQL and other technology. Presented at the PostgreSQL Conference West, in Seattle, October 2009.
Presented by Martijn van Groningen, SearchWorkings - See conference video - http://www.lucidimagination.com/devzone/events/conferences/lucene-revolution-2012
In the real world data isn’t flat. Data is often modelled into complex models. Lucene is document oriented and doesn’t support relations natively. The only way you could index this data is by de-normalizing the relations in a document with many fields and execute subsequent queries. Subsequent queries can be expensive and data gets duplicated. This isn’t always ideal. Recently Solr and Lucene provide features that allow you to join and group. You can join and group on fields across documents and still have the power of Lucene’s awesome free text search. In this presentation, we’ll look at these new alternatives, the advantages and disadvantages and how these features can be utilized. how these new capabilities impact the design of Solr-based search applications primarily from infrastructure and operational perspectives.
Slides accompanying a presentation delivered at the VII Congresso Nacional de Arquivologia in Fortaleza, Brazil, on October 19th, 2016. The slides provide an overview of the AtoM project's history, its maintenance by Artefactual, and its development philosophy, before proceeding to examine the application as a component used in a digital preservation ecosystem. Aspects of ISO 16363:2012, the Audit and Certification of Trustworthy Digital Repositories standard, are used to evaluate how AtoM can support description, management, administration, and access functions when used to maintain a chain of custody in a trustworthy digital repository ecosystem.
Redis is a popular, powerful, and—most of all—FAST database. Developers worldwide use Redis as a Cache, a session store, a message bus, and even as their regular database. In this session, we'll introduce Redis, and learn some of the key design patterns that you can use with Redis. Then we'll go over how Redis fits into the ecosystem, and how to use it in our applications—including some of the major gotchas to avoid.

MySQL Database Architectures - High Availability and Disaster Recovery SolutionMiguel Araújo
MySQL InnoDB ClusterSet brings multi-datacenter capabilities to our solutions and makes it very easy to set up a disaster recovery architecture. Think multiple MySQL InnoDB Clusters into one single database architecture, fully managed from MySQL Shell and with full MySQL Router integration to make it easy to access the entire architecture.
This presentation covers the various solutions of MySQL for High Availability, Replication, and Disaster Recovery, with a special focus on InnoDB ClusterSet:
- The various features of InnoDB Clusterset
- How to setup MySQL InnoDB ClusterSet
- Ways to migrate from an existing MySQL InnoDB Cluster into MySQL InnoDB ClusterSet
- How to deal with various failures
- The various features of router integration make the connection to the database architecture easy.
Natural Language Search with Knowledge Graphs (Activate 2019)Trey Grainger
To optimally interpret most natural language queries, its important to understand a highly-nuanced, contextual interpretation of the domain-specific phrases, entities, commands, and relationships represented or implied within the search and within your domain.
In this talk, we'll walk through such a search system powered by Solr's Text Tagger and Semantic Knowledge graph. We'll have fun with some of the more search-centric use cases of knowledge graphs, such as entity extraction, query expansion, disambiguation, and pattern identification within our queries: for example, transforming the query "best bbq near activate" into:
{!func}mul(min(popularity,1),100) bbq^0.91032 ribs^0.65674 brisket^0.63386 doc_type:"restaurant" {!geofilt d=50 sfield="coordinates_pt" pt="38.916120,-77.045220"}
We'll see a live demo with real world data demonstrating how you can build and apply your own knowledge graphs to power much more relevant query understanding like this within your search engine.
Kerberos is the system which underpins the vast majority of strong authentication across the Apache HBase/Hadoop application stack. Kerberos errors have brought many to their knees and it is often referred to as “black magic” or “the dark arts”; a long-standing joke that there are so few who understand how it works. This talk will cover the types of problems that Kerberos solves and doesn’t solve for HBase, decrypt some jargon on related libraries and technology that enable Kerberos authentication in HBase and Hadoop, and distill some basic takeaways designed to ease users in developing an application that can securely communicate with a “kerberized” HBase installation.
php complete reference with database concepts for beginners is generally useful for those who want to start the career as a php developer. given each and every information right from the scratch to understand for the beginners and students as well. I hope this will help you a lot for the beginners to start the career.

OSCON 2018 Getting Started with Hyperledger IndyTracy Kuhrt
Presented at OSCON 2018. Hyperledger Indy is a distributed ledger built for decentralized identity and is one of the open source frameworks hosted by Hyperledger. It provides tools, libraries, and reusable components for creating and using independent digital identities rooted on blockchains or other distributed ledgers. In this presentation, I introduce The Linux Foundation and Hyperledger. We look at Decentralized Identity Concepts -- identity models, decentralized identity, zero-knowledge proofs, and verifiable credentials. We look at a demo that utilizes Hyperledger Indy and these concepts. We then look at Hyperledger Indy's software stack and roadmap and touch on how you can get involved.
