Tungsten Clustering depends on a number of prerequisites and best practices to function optimally. In this blog post, we explore a critical, yet easily-overlooked step when installing a Tungsten Cluster node - configuring the available number of open files when using `systemd` control.

Tungsten Clustering depends on a number of prerequisites and best practices to function optimally. In this blog post, we explore a critical, yet easily-overlooked step when installing a Tungsten Cluster node - setting up start at boot, ideally under `systemd` control.

Recently a customer asked, “Are there any issues with running a specific node with parallel apply enabled, and the rest of the nodes using a single stream (parallel disabled)? Just curious because that would be easiest for A/B testing of the replication effects.” Firstly, the answer is yes, you may certainly enable Parallel Apply on a single node within a Tungsten Cluster.

In this blog post we explore the implications and best practices for using Parallel Apply in this way.

Upgrades are a normal, expected part of all software lifecycles, and Tungsten is no exception. Keep your software up-to-date to ensure compatibility, supportability and the lowest risk possible to your operation.
