Module processor 

Query processor — maps logical operators to physical operators and executes them.

Pipeline execution model:

1. Scan operators produce raw DataChunks
2. Filter removes non-matching rows
3. Projection selects/transforms columns
4. Limit/OrderBy/Aggregate are applied last

Enums

SchemaDdlOp
