Elassandra: Elasticsearch as a Cassandra Secondary Index (Rémi Trouville, Vin...DataStax
?
Many companies use both elasticsearch and cassandra, typically in the form of logs or time series, but managing many softwares at a large scale can be quite challenging. Elassandra tightly integrates elasticsearch within cassandra as a secondary index, allowing near-realtime search with all existing elasticsearch APIs, plugins and tools like Kibana. We will present the core concepts of elassandra and explain how it draws benefit from internal cassandra features to make elasticsearch masterless, scalable with automatic resharding, more reliable and more efficient than deploying both softwares. We will also explore the bidirectional mapping : the way elasticsearch automatically creates the corresponding cassandra schema and the way elasticsearch indexes an existing cassandra table. Furthermore, we will share some use cases and benchmark results demonstrating practical use of elassandra to scale-out, re-index with zero-downtime, search and visualize data with various tools.

Powering Predictive Mapping at Scale with Spark, Kafka, and Elastic Search: S...Spark Summit
?
The document discusses powering predictive mapping at scale using the SMACK stack, which includes Spark, Kafka, and Elasticsearch. It describes how the SMACK stack can ingest millions of events per second from connected devices, store the data in Apache Spark, and allow real-time and batch processing of the data. It also provides an example of using the stack for real-time tracking of geo-enabled IoT devices and demonstrates the data flow and a demo of the system.
The document discusses the role of local food in economic recovery in the Shasta/Lassen region of northern California. It finds that the region loses over $1 billion annually from purchasing food and farm inputs from outside the region, more than double the value of food produced locally. Developing stronger local food systems could help keep more of this wealth circulating within the regional economy.

This document discusses implementing CMMI process improvements using open-source tools. It outlines a roadmap for CMMI implementation including defining processes and templates, version control of documents and source code, and relating process areas and practices. It provides examples of open-source and proprietary tools that can be used for different CMMI process areas like project management, engineering, and support. The document also shares the experience of Multicert, who implemented CMMI DEV v1.3 using a mix of open-source and proprietary tools, starting with processes before selecting tools, and controlling acquisition and maintenance costs.
This document summarizes key topics from the first chapter of Ian Sommerville's Software Engineering textbook, 7th edition. It introduces software engineering, explaining its importance and how economies depend on software. Software engineering aims to develop software using systematic methods and tools. The document discusses what software is, differences between software engineering and computer science, software processes and models, costs of software engineering, and professional responsibilities of software engineers.

This document provides an overview and practical hints for implementing the 5S method in healthcare facilities. 5S is a workplace organization method originally developed in Japan that involves sorting, setting, shining, standardizing, and sustaining improvements. The document outlines the objectives of 5S as improving healthcare quality, infrastructure maintenance, and health and safety. It then provides specific guidance on implementing the first two S's - sorting/elimination and setting - with examples of removing unnecessary items, designating storage areas, and using visual cues like labels and signs. The overall aim is to organize workspaces for maximum efficiency and safety.
