Feed: Planet MySQL; Author: ScaleGrid.io; MySQL semisynchronous replication provides improved data integrity because when a commit returns successfully, it’s known that the data exists in at least two places – the master and its slave. In this blog post, we review some of the MySQL configurations that influence the data integrity and performance aspects of semisynchronous replication. We’ll be using InnoDB storage engine and GTID-based replication in a 3-node replica set (master and 2 slaves), which will ensure there is redundancy in the slaves. This means that if there are issues with one slave, we can fall back on the ... Read More

Feed: Planet MySQL; Author: Severalnines; Automated failover is pretty much a must have for many applications - uptime is taken for granted. It’s quite hard to accept that an application is down for 20 or 30 minutes because someone has to be paged to log in and investigate the situation before taking action. In the real world, replication setups tend to grow over time to become complex, sometimes messy. And there are constraints. For instance, not every node in a setup makes a good master candidate. Maybe the hardware differs and some of the replicas have less powerful hardware as ... Read More

Feed: Databasejournal.com - Feature Database Articles. Author: . Typical big data applications have a load phase, where a snapshot of data is extracted from operational systems, transformed and cleaned, and then loaded into your big data appliance. Analysts and data scientists can then execute business analytics (BI) queries against the data store in search of patterns and potential marketing opportunities and cost savings. One disadvantage of this architecture is that your appliance becomes more like a large data warehouse, in that it does not contain the most up-to-date data. IBM now provides an option to configure its Db2 version 11 ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Tetiana Boichenko. Machine learning in finance may work magic, even though there is no magic behind it (well, maybe just a little bit). Still, the success of machine learning project depends more on building efficient infrastructure, collecting suitable datasets, and applying the right algorithms. Machine learning is making significant inroads in the financial services industry. Let’s see why financial companies should care, what solutions they can implement with AI and machine learning, and how exactly they can apply this technology. Definitions We can define machine learning (ML) as a subset of data science that uses ... Read More

Feed: Planet MySQL; Author: Severalnines; Before you attempt to perform any schema changes on your production databases, you should make sure that you have a rock solid rollback plan; and that your change procedure has been successfully tested and validated in a separate environment. At the same time, it’s your responsibility to make sure that the change causes none or the least possible impact acceptable to the business. It’s definitely not an easy task. In this article, we will take a look at how to perform database changes on MySQL and MariaDB in a controlled way. We will talk about ... Read More

Feed: MemSQL Blog. Author: Rick Negrin. It’s time for us to admit what we have all known is true for a long time; NoSQL is the wrong tool for many of the modern application use cases, and it’s time that we move on. NoSQL came into existence because the databases at the time couldn’t handle the scale required. The rise of this new generation of data services solved many of the problems of web scale and rapidly growing data sets when it was created more than a decade ago. NoSQL also offered a new, cost-effective method for cold storage/occasional batch ... Read More
