Methods

The update method enables you to update the vector, metadata, or data of a vector.

​
Update Example

from upstash_vector import Index

index = Index.from_env()

updated = index.update(
    id="id1",
    metadata={"new": "metadata"},
    data="new-data",
)

print(updated)

​
Patch Metadata Example

It is also possible to patch metadata (update or delete existing fields or set new fields) according the JSON Merge Patch algorithm. 
from upstash_vector import Index
from upstash_vector.types import MetadataUpdateMode

index = Index.from_env()

updated = index.update(
    id="id2",
    metadata={
        "existing-field": "new-value",
        "existing-field-to-delete": None,
        "new-field": "new-value",
    },
    metadata_update_mode=MetadataUpdateMode.PATCH,
)

print(updated)
Also, you can specify a namespace to operate on. When no namespace is provided, the default namespace will be used. 
index.update(..., namespace="ns")
