Feed: AWS Compute Blog. Author: James Beswick. In the Operating Lambda series, I cover important topics for developers, architects, and systems administrators who are managing AWS Lambda-based applications. This two-part series discusses core security concepts for Lambda-based applications. Part 1 explains the Lambda execution environment and how to apply the principles of least privilege to your workload. This post covers securing workloads with public endpoints, encrypting data, and using AWS CloudTrail for governance, compliance, and operational auditing. Securing workloads with public endpoints For workloads that are accessible publicly, AWS provides a number of features and services that can help mitigate ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Monika Sangwan. Vitalik Buterin (https://vitalik.ca) conceptualized Ethereum (https://ethereum.org) in November, 2013. The core idea proposed was the development of a Turing-complete language that allows the development of arbitrary programs (smart contracts) for blockchain and Decentralized Applications (DApps). This concept is in contrast to Bitcoin, where the scripting language is limited and only allows necessary operations. The EVM is a simple stack-based execution machine that runs bytecode instructions to transform the system state from one state to another. The EVM is a Turing-complete machine but is limited by the amount of gas ... Read More

Feed: Planet PostgreSQL. By Ryan Lambert -- Published February 21, 2021My previous two posts set the stage to evaluate declarative Postgres partitioning for OpenStreetMap data. This post outlines what I found when I tested my plan and outlines my next steps. The goal with this series is to determine if partitioning is a path worth going down, or if the additional complexity outweighs any benefits. The first post on partitioning outlined my use case and why I thought partitioning would be a potential benefit. The maintenance aspects of partitioning are my #1 hope for improvement, with easy and fast loading ... Read More

Feed: MariaDB Knowledge Base Article Feed. Author: . ColumnStore uses a smart structure called an Extent Map to provide a logical range for partitioning and remove the need for indexing, manual table partitioning, materialized views, summary tables and other structures and objects that row-based databases must implement for query performance. Extents are logical blocks of space that exist within a physical segment file, and is anywhere between 8 and 64 MB in size. Each Extent supports the same number of rows, with smaller data types using less disk space. The Extent Map catalogs Extents to their corresponding blocks (LBID's), along ... Read More
