How can I create tables in Unity Catalog from a Delta Live Tables pipeline, and what permissions are required?
To create tables in Unity Catalog from a Delta Live Tables pipeline, you need to have the following requirements:

1. You must have USE CATALOG privileges on the target catalog.
2. You must have CREATE MATERIALIZED VIEW and USE SCHEMA privileges in the target schema if your pipeline creates materialized views.
3. You must have CREATE TABLE and USE SCHEMA privileges in the target schema if your pipeline creates streaming tables.

If a target schema is not specified in the pipeline settings, you must have CREATE MATERIALIZED VIEW or CREATE TABLE privileges on at least one schema in the target catalog.

Regarding the process of creating tables in Unity Catalog from a Delta Live Tables pipeline, you can define a catalog in Unity Catalog where your pipeline will persist tables and read data from Unity Catalog tables. However, it's important to note that existing pipelines cannot be upgraded to use Unity Catalog, and a single pipeline cannot write to both the Hive metastore and Unity Catalog.
