Gofer is a scalable stateless proxy architecture for DBI that is transport independent, highly configurable, efficient, well tested, scalable, and simple. It consists of a simple request/response protocol, a DBI proxy driver called DBD::Gofer, a request executor module, pluggable transport modules like HTTP, SSH, and Gearman, and an extensible client configuration mechanism. It aims to minimize round trips and supports connection pooling to improve performance and scalability.
This document discusses nested data parallelism in Haskell. It begins with an overview of task parallelism versus data parallelism. It then discusses flat data parallelism, where sequential operations are applied to bulk data, and nested data parallelism, where parallel operations can be recursively applied to bulk data. This opens up a wider range of applications compared to flat data parallelism. The document outlines some of the challenges of implementing nested data parallelism and discusses how it has been done through techniques like flattening the nested structure and aggressive fusion of operations. It describes work done in Haskell to implement a compiler for nested data parallelism using these techniques.

Today's high-traffic web sites must implement performance-boosting measures that reduce data processing and reduce load on the database, while increasing the speed of content delivery. One such method is the use of a cache to temporarily store whole pages, database recordsets, large objects, and sessions. While many caching mechanisms exist, memcached provides one of the fastest and easiest-to-use caching servers. Coupling memcached with the alternative PHP cache (APC) can greatly improve performance by reducing data processing time. In this talk, Ben Ramsey covers memcached and the pecl/memcached and pecl/apc extensions for PHP, exploring caching strategies, a variety of configuration options to fine-tune your caching solution, and discusses when it may be appropriate to use memcached vs. APC to cache objects or data.

NoSQL databases such as Redis, MongoDB and Cassandra are emerging as a compelling choice for many applications. They can simplify the persistence of complex data models and offer significantly better scalability and performance. However, using a NoSQL database means giving up the benefits of the relational model such as SQL, constraints and ACID transactions. For some applications, the solution is polyglot persistence: using SQL and NoSQL databases together.
In this talk, you will learn about the benefits and drawbacks of polyglot persistence and how to design applications that use this approach. We will explore the architecture and implementation of an example application that uses MySQL as the system of record and Redis as a very high-performance database that handles queries from the front-end. You will learn about mechanisms for maintaining consistency across the various databases.
A presentation about the problems you'll face when dealing with the relational model and highly customizable general-purpose projects, with a look at the NoSQL word focusing on a real solution, a graph database.

Results showed hash access provided CPU savings compared to non-hash access when data is relatively static. XML schema validation was moved to the engine for improved performance.
Delphix allows databases to run as software rather than hardware, using less space while maintaining full functionality and performance. It turns database servers into a single, virtual authority that can consolidate databases and instantly provision copies for development, testing, and other non-production uses. This cuts capital expenses by 50% and operational expenses by 90% while accelerating innovation by eliminating the time and costs associated with copying and moving databases between environments.
This document discusses IBM DB2 10.5 with BLU Acceleration. It introduces BLU Acceleration as a new technology that uses column-organized tables to provide significant improvements to storage, query performance, ease of use, and time-to-value for analytic workloads. The document outlines seven main ideas behind BLU Acceleration, including compute-friendly encoding and compression, keeping data compressed during evaluation, multiplying the power of CPUs using SIMD processing, core-friendly parallelism, working directly on columns to minimize I/O, and extreme data compression.
The document discusses balancing performance, capacity, and cost for cloud data storage. It notes that most data follows a pattern of occasional reads after initial writes, but some data is frequently read and written. Effective cloud storage needs high capacity and high performance at a lower cost than on-premises storage. While cloud storage was initially just about capacity, it now requires performance for active uses like file synchronization and big data. Performance is needed for cloud computing to be faster and cheaper than alternatives. The document outlines strategies for increasing storage performance like intelligent data placement algorithms and tiering for performance rather than just capacity. This enables cloud providers to reduce costs and increase revenue.

Architecting for a cost effective Windows Azure solutionMaarten Balliauw
Cloud computing and platforms like Windows Azure promise to be "the next big thing" in IT. This is certainly true as there are a lot of advantages to cloud computing. Computing and storage become an on-demand story that you can use at any time, paying only for your effective usage. But this also poses a problem: if a cloud application is designed like one would design a regular application chances are that the cost perspective of that application will not be as expected. This session covers common pitfalls and hints on improving the cost effectiveness of a Windows Azure solution.

Webinar: Designing a schema for a Data WarehouseFederico Razzoli
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.
