Google has introduced a new feature to its BigQuery migration assessment tool, allowing users to share aggregated assessment results more widely. This update, announced on July 16, 2024, is currently in preview.
Key Features of the Update
Aggregated Dataset Creation: When running a migration assessment for Amazon Redshift, Teradata, or Snowflake, the service now creates an additional dataset containing highly aggregated assessment results.
Data Privacy: The aggregated dataset excludes query logs, ensuring that no personally identifiable information (PII) or business-sensitive information is visible.
Expanded Sharing Capabilities: Users can share this aggregated dataset with individuals outside their project, potentially facilitating broader collaboration and decision-making.
BigQuery Migration Assessment Overview
The BigQuery migration assessment tool helps users plan and review the migration of existing data warehouses to BigQuery. It offers several functions:
- Cost assessment for data storage in BigQuery
- Workload optimization suggestions for potential cost savings
- Migration plan preparation, including time and effort estimates
Intended Users
This feature is designed for users familiar with the Google Cloud console and the batch SQL translator. It aims to provide a more comprehensive view of migration feasibility and potential outcomes.
Availability
The new aggregated dataset feature is currently in preview, indicating that it may undergo changes before a full release.
This update to BigQuery's migration assessment tool reflects ongoing efforts to enhance data warehouse migration processes, providing users with more flexible ways to share and analyze migration-related information while maintaining data privacy.
