In this benchmark, we hope to learn more about how they leverage the directly attached SSD in a cloud environment. The benchmark is designed for running Apache HBase and Apache Cassandra in an optimal production environment. This means using ... Read More

Feed: Percona Database Performance Blog. Author: Vadim Tkachenko. Vadim Tkachenko  | September 13, 2017 |  Posted In: Database Monitoring, Insight for DBAs, MySQL, Yandex ClickHouse PREVIOUS POST In this blog, I’ll look at how to use ClickHouse for parallel log processing. Percona is seen primarily for our expertise in MySQL and MongoDB (at this time), but neither is quite suitable to perform heavy analytical workloads. There is a need to analyze data sets, and a very popular task is crunching log files. Below I’ll show how ClickHouse can be used to efficiently perform this task. ClickHouse is attractive because it has multi-core parallel ... Read More
