These enhancements were added for all platforms unless specified in the title for a specific platform.
VantageCloud Lake Supported Azure Regions
VantageCloud Lake on Azure is now available in the following regions:
| VantageCloud Lake Supported Azure Regions | |
|---|---|
| Region Name | Region |
| East US 2 (Virginia) | eastus2 |
| Brazil South (Sao Paulo) | brazilsouth |
Support for Multi-Node Cliques (AWS Only)
Primary cluster supports multi-node cliques (MNC) on the AWS platform, in addition to the already supported single-node clique (SNC).
MNC provides a faster recovery time from compute failure and mitigates impact to system level availability due to storage volume failure by offering higher durable storage.
Support for High I/O Instance Types (AWS Only)
When creating an environment, the Organization Admin can choose High I/O instance types. High I/O instances are network optimized. They support throughput but at a higher consumption rate. These instances are only available in certain regions.
Provisioned IOPS SSD (io2 block storage) on AWS Only
Under Advanced Options, the Organization Admin can choose to use IOPS SSD (io2 block storage). This storage is automatic for more than 10 nodes and is required for multi-node cliques.
Cost Estimates when Provisioning Multi-Node Cliques and IOPS SSD (AWS Only)
When provisioning an environment you can see the estimated cost of Multi-Node Cliques, and IOPS SSD. For example, selecting gp3 block storage costs less than IOPS SSD (io2 block storage). The actual costs are shown on the Consumption page.
128 Node Support for Primary Cluster
The organization admin can now request 128 nodes as the instance count when creating an environment.
Variable AMPs per Instance for Primary Cluster
This feature is once again available for both AWS and Azure. You can choose the number of AMPs per instance (API) for the primary cluster when configuring your environment using the VantageCloud Lake Console (). See Variable AMPs per Instance for Primary Cluster.
Availability Zone Provisioning (AWS only)
You can deploy to a specific availability zone (AZ) within your region where you have other applications running to improve performance and cost efficiency. See Step 1: Sign On and Create Your First Environment.
Personal Access Tokens
Personal Access Tokens can be used with Flow, user-defined functions, and the Open Analytics Frameworks. You can upload a public key or have Teradata generate a key pair. See Create a Personal Access Token.
Answering Questions with ask.ai
Azure: ask.ai was previously a limited availability feature is now GA on Azure.
ask.ai allows you to use a chat bot interface to ask questions using natural language. Access ask.ai using in the left sidebar.
Users with different roles can get different information according to their needs.
- What is the current consumption of this environment?
- Which region was this environment provisioned in?
- What is the syntax for a SQL function (for example, create table)?
- Describe the NaiveBayes Classifier function.
- Give me SQL for an nPath statement.
- What is a compute group?
No information is sent to the cloud service provider. Content is retrieved from Teradata products such as documentation and function descriptions. This release does not provide access to your data.
Data Copy Updates (AWS only)
Data Copy deployment is handled exclusively by Teradata Support. Contact https://support.teradata.com for setup and configuration.
Supervised Learning Algorithm
TD_NaiveBayes and TD_NaiveBayesPredict functions are used for solving classification problems. A probabilistic classifier algorithm is used to predict on the basis of the probability of an object. See TD_NaiveBayes and TD_NaiveBayesPredict.
Azure Service Principal Authorization Supported on Native Object Store
Azure service principal allows you to set restricted authorization to applications and services accessing Azure external object storage.- For applications, a service principal is used to authenticate and authorize the application to access Azure resources with the necessary permissions, without using user credentials.
- For users, a service principal can be used if you need to grant limited permissions to an automated process or a service, acting on behalf of the user, to perform specific tasks in Azure.
User Profile Time Zone in Lake Console
Users can access the Account Settings page in the Lake console to specify a preferred time zone within the Lake console, and select their preferred date and time formats for display.
