Examples

from pymilvus import DataType, FieldSchema, StructFieldSchema

vector = FieldSchema(
    name="vector_02",
    dtype=DataType.FLOAT_VECTOR,
    dim=768,
)

varchar = FieldSchema(
    name="varchar_02",
    dtype=DataType.VARCHAR,
    max_length=512
)

# Create dictionary representation 
schema_dict = {
    "fields": [     
        vector.to_dict(),
        varchar.to_dict()                
    ]
}  

# Reconstruct schema from dictionary 
schema = StructFieldSchema(name="struct_schema", fields=[vector]).construct_from_dict(schema_dict)  

print(schema)

# Output
