Network volumes in Kubernetes provide great flexibility, but still, nothing beats local volumes from direct-attached storage in the sense of database performance.
I want to explore ways to deploy both Percona Kubernetes Operators (Percona Kubernetes Operator for Percona XtraDB Cluster and Percona Kubernetes Operator for Percona Server for MongoDB) using local volumes, both on the […]
Abstract: Storage engine algorithmic gains have mostly settled and Moore’s law for CPU speed is bottoming out, but database performance still stands to increase ~10x thanks to continuing NAND Flash improvement, Optane, Flash-idiomatic SSD drives (e.g. OpenChannel, Zoned Namespaces), KeyValue SSD, etc. The downside is each storage engine revolution historically has broken encapsulation/reuse and […]

Making backups over the network can be done in two ways: either save on disk and transfer or just transfer without saving. Both ways have their strong and weak points. The second way, particularly, is highly dependent on the upload speed, which would either reduce or increase the backup time. Other factors that influence […]

Last year, I wrote a post focused on the performance of the 3D_XPoint technology and sold under the Optane brand. Those devices are outperforming regular flash devices and have higher endurance. In the context of this post, I found they are also very good at handling the fsync call, something many flash devices are […]
