Testing the Value of ScaleFlux Computational Storage Drive (CSD) for PostgreSQL

ScaleFlux Computational Storage Drive PostgreSQL

Some time ago we at Percona were approached by ScaleFlux Inc to benchmark their latest hardware appliance, the CSD 2000 Drive, which is a next-generation SSD computational storage drive. It goes without saying that a truly relevant report requires us to be as honest and as forthright as possible. In other words, my mission […]

Deploying Percona Kubernetes Operators with OpenEBS Local Storage

Deploying Percona Kubernetes Operators with OpenEBS Local Storage

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 […]

DBA Concerns About Next-Gen, Non-Volatile Memory Storage Products

DBA Concerns Memory Storage

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 […]

Comparing S3 Streaming Tools with Percona XtraBackup

Comparing S3 Streaming Tools

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 […]
