Free trial FAQs
When you sign up for Materialize, you get a free trial account so you can explore the product and start building! This page answers some frequently asked questions about free trials.
What are the limits of a free trial?
In Materialize, cluster replicas are the physical resources for doing computational work. Cluster replicas come in various sizes, and each size has a credit consumption rate.
During your free trial, your credit consumption rate across all replicas in a region cannot exceed 4 credits per hour at any point in time. This limit should accommodate most trial scenarios.
For example, let’s say you have 3 clusters in a region:
|Cluster||Replicas||Credits per hour|
||1 (0.5 each)|
In this case, your credit consumption rate would be 2 credits per hour, which is under the rate limit of 4 credits per hour.
How long does a free trial last?
If you need additional time, please chat with our team. Otherwise, Materialize will delete your resources and data at the end of the trial period.
How do I monitor my credit consumption rate?
To see your current credit consumption rate, measured in credits per hour, run the following query:
SELECT sum(s.credits_per_hour) AS credit_consumption_rate FROM mz_cluster_replicas r JOIN mz_internal.mz_cluster_replica_sizes s ON r.size = s.size;
For example, if you start your free trial with the getting started guide, you’ll end up consuming credits at a rate of
3.5 per hour:
credit_consumption_rate ------------------------- 3.5 (1 row)
Can I go over the credit rate limit?
No, you cannot go over the rate limit of 4 credits per hour at any time during your free trial. If you try to add a replica that puts you over the limit, Materialize will return an error.
If you need additional resources during your trial, chat with our team.
