Feed: Clustrix Blog. Author: Ken Geiselhart. In the world of databases, having multiple copies of your database helps to serve your business in a multitude of ways. To achieve this, replication is used. Replication copies the contents of one server called a Primary to one or more servers called Replicas.One advantage of replication is the ability to separate the read requests from the write requests and direct those reads to a Replica, offloading that portion of a workload away from the Primary improving performance on the Primary. The main difference in basic replication, between a Primary and a Replica, is ... Read More

Feed: Blog – Hazelcast. Author: Jaromir Hamala. Hazelcast Jet 3.2 introduces stateful map, filter, and flatmap operations, which are very strong primitives. In this blog, I am going to show you how to use stateful filter for detecting and removing duplicate elements in a stream. Why Deduplication? Deduplication is often used to achieve idempotency or effectively-once delivery semantics in messaging systems. Imagine you have a microservices architecture where individual microservices use a message broker to communicate with each other. Achieving exactly-once semantics is a hard problem. If you cannot have exactly-once then you are typically left with at-most-once and at-least-once ... Read More

It does this by doing ... Read More

Feed: Clustrix Blog. Author: Anders Karlsson. There are several ways to load data into MariaDB Platform, and some are better than others. The two basic ways are either to use LOAD DATA INFILE / LOAD DATA LOCAL INFILE, which is very fast, in particular the non-LOCAL one and then we have the plain INSERT statement. When using an INSERT statement you may pass an array to MariaDB Server, like thisINSERT (column1,column2) VALUES(, ),(, ) Nothing special with that, but what we will cover in this blog is another way of doing INSERTs using arrays, one which uses the MariaDB API ...

Video Transcript Hi, my name is Manjot Singh. I’m here to talk to you about MariaDB’s classic replication model. A lot of times you have a primary server and you have an application. That application connects to that primary server and does its work – it saves data, reads data. And what you may have ... Read More
