pyarrow.unify_schemas¶
- pyarrow.unify_schemas(schemas)¶
Unify schemas by merging fields by name.
The resulting schema will contain the union of fields from all schemas. Fields with the same name will be merged. Note that two fields with different types will fail merging.
- The unified field will inherit the metadata from the schema where
that field is first defined.
- The first N fields in the schema will be ordered the same as the
N fields in the first schema.
The resulting schema will inherit its metadata from the first input schema.
