object DatasetManager extends Logging
DatasetManager is responsible for materializing tables in the catalog based on the given
graph. For each table in the graph, it will create a table if none exists (or if this is a
full refresh), or merge the schema of an existing table to match the new flows writing to it.

- case class TableMaterializationException(tableName: String, cause: Throwable) extends Exception with NoStackTrace with Product with Serializable
Wraps table materialization exceptions.
Wraps table materialization exceptions.
The target use case of this exception is merely as a means to capture attribution - 1. Indicate that the exception is associated with table materialization. 2. Indicate which table materialization failed for.
- tableName
The name of the table that failed to materialize.
- cause
The underlying exception that caused the materialization to fail.
