Cache and Drupal

Nov 6, 2009Download as odp, pdf0 likes701 views

A cache stores data that is expensive to fetch or compute to improve performance. Drupal uses caching extensively to store node data, blocks, pages and other content to avoid unnecessary database queries or PHP processing. Caches in Drupal can be stored and retrieved using functions like cache_get() and cache_set() and come in forms like block, content, page and update caches.

A cache (pronounced /kæʃ/ ) is a collection of data duplicating original values Stored elsewhere or computed earlier, where the original data is expensive to fetch (owing to longer access time) or to compute, compared to the cost of reading the cache. Wikipedia

Presented at the webinar, June 26, 2019 Materialized views are a killer feature of ClickHouse that can speed up queries 20X or more. Our webinar will teach you how to use this potent tool starting with how to create materialized views and load data. We'll then walk through cookbook examples to solve practical problems like deriving aggregates that outlive base data, answering last point queries, and using AggregateFunctions to handle problems like counting unique values, which is a special ClickHouse feature. There will be time for Q&A at the end. At that point you'll be a wizard of ClickHouse materialized views and able to cast spells of your own.

Webinar: Secrets of ClickHouse Query Performance, by Robert HodgesAltinity Ltd

From webinars September 11 and September 17, 2019 ClickHouse is famous for speed. That said, you can almost always make it faster! This webinar uses examples to teach you how to deduce what queries are actually doing by reading the system log and system tables. We'll then explore standard ways to increase query speed: data types and encodings, filtering, join reordering, skip indexes, materialized views, session parameters, to name just a few. In each case we'll circle back to query plans and system metrics to demonstrate changes in ClickHouse behavior that explain the boost in performance. We hope you'll enjoy the first step to becoming a ClickHouse performance guru! Speaker Bio: Robert Hodges is CEO of Altinity, which offers enterprise support for ClickHouse. He has over three decades of experience in data management spanning 20 different DBMS types. ClickHouse is his current favorite. ;)

ClickHouse materialized views - a secret weapon for high performance analytic...Altinity Ltd

ClickHouse materialized views allow you to precompute aggregates and transform data to improve query performance. Materialized views can store precomputed aggregates from a source table to speed up aggregation queries over 100x. They can also retrieve the last data point for each item over 100x faster than scanning the raw data table. Materialized views provide a way to optimize data storage layout and indexing to improve query efficiency.

Schema Design by Chad Tindel, Solution Architect, 10genMongoDB

MongoDB’s basic unit of storage is a document. Documents can represent rich, schema-free data structures, meaning that we have several viable alternatives to the normalized, relational model. In this talk, we’ll discuss the tradeoff of various data modeling strategies in MongoDB using a library as a sample application. You will learn how to work with documents, evolve your schema, and common schema design patterns.

Jan 2012 HUG: RHadoopYahoo Developer Network

RHadoop is an open source project aiming to combine two rising star in the analytics firmament: R and Hadoop. With more than 2M users, R is arguably the dominant language to express complex statistical computations. Hadoop needs no introduction at HUG. With RHadoop we are trying to combine the expressiveness of R with the scalability of Hadoop and to pave the way for the statistical community to tackle big data with the tools they are familiar with. At this time RHadoop is a collection of three packages that interface with HDFS, HBase and mapreduce, respectively. For mapreduce, the package is called rmr and we tried to give it a simple, high level interface that's true to the mapreduce model and integrated with the rest of the language. We will cover the API and provide some examples.

Prometheus Monitoring MixinsGrafana Labs

Presented at KubeCon Copenhagen in May 2018. Prometheus offers powerful open source monitoring and alerting - but that comes with higher degrees of freedom, making pre-configure monitoring configuration hard to build. Simultaneously, its becoming accepted wisdom that the developers of a given software package are best placed to operate said software, or at least construct the basic monitoring configuration. In this talk we present a technique for using Jsonnet (a configuration language from Google) for packaging and deploying “Monitoring Mixins” - extensible and customisable combinations of dashboards and alert definitions. This technique allows developers of open source projects to publish best-practice monitoring configurations alongside their code, and for users to consume it, customise it and stay up to date. We will present example Mixins for Kubernetes and other services such as Consul and Cassandra.

Hadoop is a system for processing large amounts of data using MapReduce and HDFS. HDFS is the storage component that splits files into blocks and stores multiple copies for reliability. MapReduce is the processing framework where mappers process key-value pairs in parallel and reducers aggregate the outputs. While Hadoop can process huge datasets, other systems like Pig, Hive, HBase, Accumulo, Avro, ZooKeeper, and Flume provide additional functionality for tasks like SQL queries, real-time processing, coordination, serialization, and data aggregation.

The document discusses the causes and effects of stress and strain in modern life. It states that increased pace, challenges, financial issues, and traffic make modern life anxious. Stress affects people physically and psychologically. It identifies three stages the body goes through when under stress, involving the nervous and hormonal systems. Prolonged stress can lead to many health problems. The document recommends foods and lifestyle changes that can help relieve stress, such as a balanced diet with raw foods, water, and antioxidants. It suggests avoiding fried, fatty, fast, and processed foods as well as alcohol and smoking when stressed. Non-food approaches like exercise, meditation, and breathing techniques can also help manage stress.

Cultural Identity, Network Action, and Customary LawSPERI

“ The CHESH-Lao Program” is the name given to the activities in Laos of the Centre for Human Ecology Studies of Highlands (CHESH). CHESH is an independent Science and Technology Association (STO) registered in Vi etnam with the Vietnam Union of Science and Technology Associations (VUSTA). It was founded in 1999 by the Vietnamese NGO, Towards Ethnic Women (TEW), to carry out research on the traditional natural resource management practices of indigenous ethnic minority peoples in the highland areas of the Mekong region of Southeast Asia. Its founder, TEW, had itself been working very closely with highland ethnic minority peoples in Vietnam, supporting village-level development projects, since 1994. In its work, TEW had developed strong critique of conventional development programmes, such as those going under the names of ‘poverty alleviation’, ‘hunger eradication’ and ‘capacity building’. Such programmes they saw as imposing outsiders’ views minority peoples’ lives. They were particularly critical of the failure of development agencies, both domestic and foreign, to listen to and learn from minority peoples. They saw this failure as resulting in interventions that were destructive of the ecological balance and close spiritual relations that minority communities had with their natural environment. In its own work, in the areas of land rights and gender relations, TEW treated ethnic minority peoples as experts in human ecology and sustainable resource management. TEW staff lived with ethnic minority communities for months at a time to learn their languages and cultures and the spiritual values behind their ways of managing natural resources. It was to research these matters more thoroughly that TEW established CHESH, in the hope that its research results would be used to improve government policies and the lives of ethnic minority peoples in the highland regions (Vandenhende: 11)

Case study: Custlaw based landforest conflict resolutions in Long Lan village...SPERI

Land conflicts take place in many places due to land loss faced by people, especially farmers with various forms of pressures. Such programs as modernization, industrialization and urbanization tend to transfer fertile agricultural land attaching high profitability and commercial possibility to other purposes. The needs for more land for modern, large-scale food production are encouraged by technocrats as the way to meet growing consumer demand. Under pressure of attracting resources for industrialization from political power and monetary power, many farmers in developing countries are forced to move from their ancestor land and lose the land to the hands of investors and transnational companies. Shortage of land to live, lack of transparency, and overlapping of ownership of land, forests and natural resources or land use rights are among the hottest constrains causing conflicts over land.

Could Virtual Threads cast away the usage of Kotlin Coroutines - DevoxxUK2025João Esperancinha

This is an updated version of the original presentation I did at the LJC in 2024 at the Couchbase offices. This version, tailored for DevoxxUK 2025, explores all of what the original one did, with some extras. How do Virtual Threads can potentially affect the development of resilient services? If you are implementing services in the JVM, odds are that you are using the Spring Framework. As the development of possibilities for the JVM continues, Spring is constantly evolving with it. This presentation was created to spark that discussion and makes us reflect about out available options so that we can do our best to make the best decisions going forward. As an extra, this presentation talks about connecting to databases with JPA or JDBC, what exactly plays in when working with Java Virtual Threads and where they are still limited, what happens with reactive services when using WebFlux alone or in combination with Java Virtual Threads and finally a quick run through Thread Pinning and why it might be irrelevant for the JDK24.
