Specifically, in many of the cases where we previously used Postgres, we now use Schemaless, a novel database sharding layer built on top of MySQL ( ). Since that time, the architecture of Uber has changed significantly, to a model of microservices and new data platforms. The early architecture of Uber consisted of a monolithic backend application written in Python that used Postgres for data persistence. Fun fact - earlier in Uber's history we'd actually moved from MySQL to Postgres before switching back for good, & though we published the article in Summer 2016 we haven't looked back since: In essence, it was due to a variety of limitations of Postgres at the time. Com isso, você terá um laboratório de simulação e estudo, conseguirá administrar este banco de dados, executar comandos SQL e muito mais. Our most popular (& controversial!) article to date on the Uber Engineering blog in 3+ yrs. Nesta publicação e vídeo aula do canal, aprenderemos a instalar o banco de dados MySQL e a ferramenta de design, desenvolvimento e administração MySQL Workbench. ![]() ![]() We use its excellent built-in full-text search, which has helped us avoid needing to bring in a tool like Elasticsearch, and we've really enjoyed features like its partial indexes, which saved us a lot of work adding unnecessary extra tables to get good performance for things like our "unread messages" and "starred messages" indexes. As a result, we were able to delete a bunch of custom queries escaping the ORM that we'd written to make the MySQL query planner happy (because postgres just did the right thing automatically).Īnd then after that, we've just gotten a ton of value out of postgres. We didn't have to do any real customization (just some tuning settings for how big a server we had), and all of our most important queries were faster out of the box. We ended up getting so frustrated that we tried out PostgresQL, and the results were fantastic. #Mysql workbench portable manualIssues ranged from bad collation defaults, to bad query plans which required a lot of manual query tweaks. However, we found that even though we were using the Django ORM for most of our database access, we spent a lot of time fighting with MySQL. Zulip started out as a MySQL project back in 2012, because we'd heard it was a good choice for a startup with a wide community. We've been using PostgreSQL since the very early days of Zulip, but we actually didn't use it from the beginning. ![]() #Mysql workbench portable licenseLicenza Launcher/Launcher License: winPenPack License AgreementĬodice Sorgente/Source Code: Launcher source - MySQLWorkbench source Licenza Software/Software License: GNU General Public License #Mysql workbench portable softwareVersione/Version: Software - X-Launcher - INI It includes everything a data modeler needs for creating complex ER models, and also delivers key features for performing difficult change management and documentation tasks that normally require much time and effort. MySQL Workbench enables a DBA, developer, or data architect to visually design, generate, and manage all types of databases including Web, OLTP, and data warehouse databases. MySQL Workbench contiene tutto ciò di cui un data modeler ha bisogno per creare modelli ER complessi, oltre a fornire le funzionalità fondamentali per l’esecuzione di attività complesse di gestione della documentazione e delle modifiche, le quali normalmente richiedono una grande quantità di tempo e lavoro ( fonte). MySQL Workbench consente a DBA, sviluppatori e data architect di progettare, generare e gestire visualmente qualsiasi tipo di database, inclusi database web, OLTP e data warehouse. ![]()
