Эксплуатация и мониторинг PostgreSQL в условиях AWS RDS: проблемы, рецепты и решения.

Все наверное слышали о таком сервисе как AWS RDS. Я расскажу о своем опыте использования AWS RDS PostgreSQL Engine: о положительных и отрицательных аспектах эксплуатации и мониторинга. В докладе будет особое внимание уделено инструментам которые помогли мне создать комфортное окружение и полюбить RDS. https://www.dropbox.com/s/v7udx5x96as5gbd/pgconf2020.pdf

Architecting petabyte-scale analytics by scaling out Postgres on Azure with Citus

The story about powering a 1.5 petabyte analytics application with 2816 cores and 18.7 TB of memory in the Citus cluster at the Microsoft. The Windows team measures the quality of new software builds by scrutinizing 20,000 diagnostic metrics based on data flowing in from 800 million Windows devices. At the same time, the team evaluates feedback from Microsoft engineers who are using pre-release versions of Windows updates. At Microsoft, the Windows diagnostic metrics are displayed on a real-time analytics dashboard called “Release Quality View” (RQV), which helps the internal “ship-room” team assess the quality of the customer experience before each new Windows update is released. Given the importance of Windows for Microsoft’s customers, the RQV analytics dashboard is a critical tool for Windows engineers, program managers, and execs.

Life cycle of Database Migration from Oracle, DB2 to PostgreSQL

Many businesses which use Database management systems like Oracle, DB2 & MS SQL are unreliable these days. Moreover, the costs incurred in maintaining these systems and its product licenses keeps on increasing. As the competitors are migrating over to the new technologies and tools available in the market, it is necessary for these businesses to migrate to new environment which is efficient, consistent and reliable to stay in the market and the technologies used in the current environment have become obsolete or no longer serve the business purpose. PostgreSQL has emerged as a top open-source RDBMS software. Since there is no licensing cost associated with it most of the companies are planning to migrate the databases which are currently running on other RDBMS like Oracle, DB2, MS SQL server to PostgreSQL. This report summarizes the various methodologies, procedures and techniques involved in successfully migrating the data from Oracle to PostgreSQL & DB2 to PostgreSQL. Migration is not a simple effort there should be proper planning and testing involved in this right from database connectivity to performance analysis. In this paper we are going to cover most of the steps which we need to consider before the migration and after the migration like choosing the correct tools for implementing the migration, time taken to migrate ,data compatibility, code conversion, application connectivity to database, database configuration parameters, performance analysis, replication setups, database monitoring, patching and backup strategies.

Хранимки as code

В рамках доклада поговорим о хранимых процедурах и функциях и коде внутри базы данных в целом. Посмотрим на хранимки с разных сторон: глазами DBA, разработчика баз данных и разработчика серверной части. Попытаемся понять что такого особенного в хранимых процедурах, что зачастую препятствует применению сложившихся практик по работе с исходным кодом. Поговорим о том как выглядят best practice по работе с кодом в разрезе хранимых процедур.

Доклад в большей степени ориентирован на разработчиков баз данных и серверных разработчиков, и является скорее мотивационным, чем хардкорно-техническим.
