You can use this form to request access to pre-general availability (pre-GA) features in BigLake tables for Apache Iceberg in BigQuery, including:
1. Multi-statement transactions
2. Table partitioning
3. Change Data Capture (CDC)
A multi-statement transaction lets you perform mutating operations, such as inserting or deleting rows on one or more tables, and either commit or roll back the changes atomically. Please refer to the product documentation for more details.
Table partitioning allows organizing data in a large table into smaller segments, called partitioned, based on the values of a specified partitioning column. We recommend using partitioning when you want to improve the query performance, especially with third-party or open-source engines, and lower query costs by reducing the amount of data that your query engine needs to scan.
With BigQuery CDC, stream row-level changes (UPSERTs and DELETEs) from your OLTP databases into BigLake Iceberg tables using the BigQuery Storage Write API. This native CDC capability eliminates the need for complex DML MERGE statements and provides a scalable, low-latency solution for replicating transactional data into managed Iceberg tables for near real-time analysis.
We enable Pre-GA feature access on a rolling basis as we process the incoming requests. We will send information, including next steps, when the feature is enabled for your organization. Completing this form does not guarantee Pre-GA access to the preview features in BigLake tables for Apache Iceberg in BigQuery.
