Feed: Redis. Author: Ross Owens. If you believe Ralph Waldo Emerson, a foolish consistency may be the hobgoblin of little minds, but when it comes to implementing a scalable, successful enterprise-level caching strategy, there’s nothing foolish about consistency. In fact, one of the greatest challenges in managing the operation of an enterprise database is maintaining cache consistency. Why do we bother with caches in the first place? The principal advantage of an enterprise cache is the speed and efficiency at which data can be accessed. While each call to the primary database can be expensive in terms of both time ... Read More

Feed: Recent Announcements. AWS AppSync is a managed GraphQL service that simplifies application development by letting you create a flexible API to securely access, manipulate, and combine data from one or more data sources. Today, we are happy to announce that AppSync now supports eviction of specific entries from AppSync’s built-in server-side cache. AppSync’s server-side caching feature can be used to help improve the performance of latency-sensitive and high-throughput applications by allowing developers to store and fetch data from a fast, in-memory, managed cache. Before today, customers could invalidate cache entries by flushing the entire cache, but could not invalidate ... Read More

Feed: Redis. Author: Will Johnston. We received a lot of good feedback on our post titled, “Learn How Redis Simplifies Your Architecture in 90 Seconds,” so we decided to do a follow-up about Redis as a cache versus Redis as both a cache and a primary database. How to replace your primary database with Redis Everyone knows Redis began as a caching database, but it has since evolved to a primary database. Many applications built today use Redis as a primary database.  However, most Redis service providers support Redis as a cache, but not as a primary database. This means ... Read More

Feed: MariaDB Knowledge Base Article Feed. Author: . This filter was introduced in MariaDB MaxScale 2.1. Overview From MaxScale version 2.2.11 onwards, the cache filter is no longer considered experimental. The following changes to the default behaviour have also been made: The default value of cached_data is now thread_specific (used to be shared). The default value of selects is now assume_cacheable (used to be verify_cacheable). The cache filter is a simple cache that is capable of caching the result of SELECTs, so that subsequent identical SELECTs are served directly by MaxScale, without the queries being routed to any server. By ... Read More

Feed: Recent Announcements. Amazon Elastic Container Registry (Amazon ECR) now supports pull through cache repositories, a new feature designed to automatically sync images from publicly accessible registries. With today’s release, customers now benefit from the download performance, security, and availability of Amazon ECR for the public images. Organizations rely on public registries for images to build or complement their container applications. The more public images that are pulled, the more teams need to ensure they stay updated with the public image’s source registry. With pull through cache repositories, there are no additional solutions or tools to manage. Using pull through ... Read More

Feed: R-bloggers. Author: Bernardo Lares. CategoryTagsIf you’ve never heard of cache (/kaSH/) before, Google it and you’ll quickly find that it is “a collection of items of the same type stored in a hidden or inaccessible place”. Basically, you have “something” stored “somewhere” so you can fetch it “sometime” later. If it sounds basic, it (can be) is! This simple technic can come quite handy when you are coding functions that take some time to gather and/or process the data you’re working with. In other words, think of those processes that take some time to run and there’s really no ... Read More

Feed: Recent Announcements. Starting today, you can launch your RDF/SPARQL or Apache TinkerPop graph application using R5d instances on Amazon Neptune. The R5d instance type is based on the Amazon EC2 Nitro System and includes local NVMe-based SSD block level storage. Neptune R5d instances introduce a lookup cache that leverages the low-latency NVMe SSD storage to improve read query performance and reduce data retrievals from storage. For use cases with frequent, repetitive lookups of property values or RDF literals, R5d instances use the lookup cache to temporarily store these values in the NVMe SSD volume for faster retrieval in the ...

Feed: Planet PostgreSQL.  Photo by Free-PhotosPgpool-II provides "query cache" feature which speeds up SELECT to database. It stores query results to specified storage (either shared memory or memcached). If same query (more precisely, SELECT query which has identical text) arrives, Pgpool-II returns the cached result without accessing the database. This is very fast because:Query results are fetched from memory, rather than database's (typically on desk) storageDoes not use CPU or memory on database serverIs there any pitfall?Whether a SELECT result is fetched from the database or cache is transparent to client. That is, you don't realize the distinction except the ... Read More

Feed: Redis Labs. Author: Maygol Kananizadeh. Digital transformation has been an ongoing journey for many organizations across industries for the past few years. However, this transformation was significantly accelerated this past year due to COVID-19. Since people’s day to day lives have become more digital, their expectations—not surprisingly—have grown much more real-time in nature. And having access to real-time data is a key component for all organizations to ensure they can deliver the best experience to their users. As the builders of a real-time data platform, we find ourselves at the center of many digital transformation projects. We believe that for ... Read More
