![]() ![]() This will come in handy later when you set up workload management (WLM). We also recommend grouping your users by type of workload (e.g. This way, you’ll have more control and better visibility into your workloads. Instead, use Redshift’s CREATE USER command, which creates a new database user account, and create individual logins to isolate your workloads-one user, one login, no exceptions. ![]() A single masteruser may work if you only have 3 to 5 users accessing Redshift, but it becomes simply intractable once you have 10 or more. As you add more users, troubleshooting bad queries starts to become harder and harder. The problem with this approach is that you lose granularity: it gets much more difficult to understand which people are doing what and running which queries. Next, the masteruser’s login gets shared, such that ETL pipelines, scheduled jobs, and dashboard tools all log in with the same user. Setting up Redshift Clusters: Don’t Use the Masteruserįor many people, the process of setting up Amazon Redshift looks like this: when launching a Redshift cluster, you create a masteruser, which by default has access to the initial database. By scrupulously avoiding these issues, you’ll be paving the way for success as the complexity of your data pipeline grows. In this post, we’ll focus on exactly the opposite topic: the top 3 things not to do when setting up an Amazon Redshift cluster. You may have already seen our article on the top performance tuning techniques for Amazon Redshift. Some of the common Redshift pain points are slow queries and lack of workload scalability. Cutting corners when setting up Redshift may create performance issues down the line, and you’ll pay the price later as your data volume and pipeline complexity grows. With Redshift, it’s easy to spin up a cluster, pump in data, and begin performing advanced analytics in under an hour.īecause it’s so easy to start using Redshift, however, data engineers often skip Redshift best practices when setting up a cluster. Setting up Redshift Clusters: Don’t use the default WLM queueĪmazon Redshift is a petabyte-scale data warehouse that has been widely adopted since its release in October 2012.Setting Up Redshift Clusters: Don't use a Single Schema.Setting up Redshift Clusters: Don't Use the Masteruser. ![]()
