Best Practices for Monitoring Vertica. We all know the health of the database is such a key aspect for making sure everything is running properly. And just like us, the Vertica database needs checks to ensure its health is maintained. This document covers everything from recovery and rebalance to monitoring DC tables. Each section provides sample queries you can run to see how to best monitor Vertica to verify it is running in the way that suits your business needs.
Best Practices for Managing Resource Pools. This document was written for Vertica administrators and walks through a few examples of how to create custom resource pools to handle both well-defined and ad-hoc workloads. The beauty of Vertica is that it excels at handling a variety of queries at the same time. When multiple queries run on the system, the queries share resources. Each query can take longer to run than if it were running alone. The resource managers helps prioritize usage and handles resources using resource pools. A resource pool is a pre-allocated subset of the system resources, with an associated queue. This document walks through use cases intended to help you create the best resource pools for managing your workload.
Node Recovery in Vertica. In Vertica Enterprise Mode, a node in the DOWN state does not participate in any transactions committed since the time the node went down. After restarting the DOWN node, that node must recover the data it missed during the down time from its buddy node before it can go back to the UP state. When the node is in the UP state, it is fully recovered and read to process all database transactions. This document assumes you already have experience recovering nodes.
Best Practices for Preparing Your Cluster for Rebalance. This document describes how to prepare your cluster for rebalance and how to estimate how long it will take to rebalance your database. Read through a customer’s experience with rebalance and learn how to make the most of the rebalance experience.
