I’m trying to create a triggered Lakebase synced table from a SDP-created materialized view.

The source MV uses Automatic CDF: row tracking is enabled and legacy CDF (delta.enableChangeDataFeed) is disabled. The Automatic CDF workspace preview is enabled (says GA now)

The producer pipeline is configured with the PREVIEW channel and pipelines.externalMetadata.enabled=true. I recreated and reran the pipeline successfully.

However, synced-table creation still says that Change Data Feed is required and suggests running ALTER TABLE ... SET TBLPROPERTIES (delta.enableChangeDataFeed=true). That would enable legacy CDF, and ALTER TABLE also cannot be used because the source is a materialized view.

Does Lakebase synced-table creation support Automatic CDF for pipeline-created materialized views? If so, how should pipeline_channel=PREVIEW be configured for the managed sync pipeline?
