Weaviate
Batch process all your records to store structured outputs in a Weaviate database.
The requirements are as follows.
-
For the Unstructured Platform: only Weaviate Cloud clusters are supported.
-
For Unstructured Ingest: Weaviate Cloud clusters, Weaviate installed locally, and Embedded Weaviate are supported.
-
For Weaviate installed locally, you will need the name of the target collection on the local instance.
-
For Embedded Weaviate, you will need the instance’s connection URL and the name of the target collection on the instance.
-
For Weaviate Cloud, you will need:
-
A Weaviate database instance. The following information assumes that you have a Weaviate Cloud (WCD) account with a Weaviate database cluster in that account. Create a WCD account. Create a database cluster. For other database options, learn more.
-
The URL and API key for the database cluster. Get the URL and API key.
-
The name of the target collection in the database. Create a collection.
An existing collection is not required. At runtime, the collection behavior is as follows:
For the Unstructured Platform:
- If an existing collection name is specified, and Unstructured generates embeddings, but the number of dimensions that are generated does not match the existing collection’s embedding settings, the run will fail. You must change your Unstructured embedding settings or your existing collection’s embedding settings to match, and try the run again.
- If a collection name is not specified, Unstructured creates a new collection in your Weaviate cluster. If Unstructured generates embeddings,
the new collection’s name will be
U<short-workflow-id>_<short-embedding-model-name>_<number-of-dimensions>
. If Unstructured does not generate embeddings, the new collection’s name will beU<short-workflow-id
.
For Unstructured Ingest:
- If an existing collection name is specified, and Unstructured generates embeddings, but the number of dimensions that are generated does not match the existing collection’s embedding settings, the run will fail. You must change your Unstructured embedding settings or your existing collection’s embedding settings to match, and try the run again.
- If a collection name is not specified, Unstructured creates a new collection in your Weaviate cluster. The new collection’s name will be
Elements
.
If Unstructured creates a new collection and generates embeddings, you will not see an embeddings property in tools such as the Weaviate Cloud Collections user interface. To view the generated embeddings, you can run a Weaviate GraphQL query such as the following. In this query, replace
<collection-name>
with the name of the new collection, and replace<property-name>
with the name of each additional available property that you want to return results for, such astext
,type
,element_id
,record_id
, and so on. The embeddings will be returned in thevector
property.
-
Weaviate requires an existing collection to have a data schema before you add data. At minimum, this schema must contain the record_id
property, as follows:
Weaviate generates any additional properties based on the incoming data.
If you have specific schema requirements, you can define the schema manually. Unstructured cannot provide a schema that is guaranteed to work for everyone in all circumstances. This is because these schemas will vary based on your source files’ types; how you want Unstructured to partition, chunk, and generate embeddings; any custom post-processing code that you run; and other factors.
You can adapt the following collection schema example for your own specific schema requirements:

The Weaviate connector dependencies:
You might also need to install additional dependencies, depending on your needs. Learn more.
The following environment variables:
-
For Weaviate installed locally,
WEAVIATE_COLLECTION
- The name of the target collection in the instance, represented by--collection
(CLI) orcollection
(Python). -
For Embedded Weaviate:
WEAVIATE_HOST
- The connection URL to the instance, represented by--hostname
(CLI) orhostname
(Python).WEAVIATE_COLLECTION
- The name of the target collection in the instance, represented by--collection
(CLI) orcollection
(Python). If no value is provided, see the beginning of this article for the behavior at run time.
-
For Weaviate Cloud:
-
WEAVIATE_CLUSTER_URL
- THE REST endpoint for the Weaviate database cluster, represented by--cluster-url
(CLI) orcluster_url
(Python). -
WEAVIATE_API_KEY
- The API key for the database cluster, represented by--api-key
(CLI) orapi_key
(Python).For the CLI, the--api-key
option here is part of theweaviate-cloud
command. For Python, theapi_key
parameter here is part of theCloudWeaviateAccessConfig
object. -
WEAVIATE_COLLECTION
- The name of the target collection in the database, represented by--collection
(CLI) orcollection
(Python). If no value is provided, see the beginning of this article for the behavior at run time.

Now call the Unstructured Ingest CLI or the Unstructured Ingest Python library. The source connector can be any of the ones supported. This example uses the local source connector:
This example sends files to Unstructured API services for processing by default. To process files locally instead, see the instructions at the end of this page.
For the Unstructured Ingest CLI and the Unstructured Ingest Python library, you can use the --partition-by-api
option (CLI) or partition_by_api
(Python) parameter to specify where files are processed:
-
To do local file processing, omit
--partition-by-api
(CLI) orpartition_by_api
(Python), or explicitly specifypartition_by_api=False
(Python).Local file processing does not use an Unstructured API key or API URL, so you can also omit the following, if they appear:
--api-key $UNSTRUCTURED_API_KEY
(CLI) orapi_key=os.getenv("UNSTRUCTURED_API_KEY")
(Python)--partition-endpoint $UNSTRUCTURED_API_URL
(CLI) orpartition_endpoint=os.getenv("UNSTRUCTURED_API_URL")
(Python)- The environment variables
UNSTRUCTURED_API_KEY
andUNSTRUCTURED_API_URL
-
To send files to Unstructured API services for processing, specify
--partition-by-api
(CLI) orpartition_by_api=True
(Python).Unstructured API services also requires an Unstructured API key and API URL, by adding the following:
--api-key $UNSTRUCTURED_API_KEY
(CLI) orapi_key=os.getenv("UNSTRUCTURED_API_KEY")
(Python)--partition-endpoint $UNSTRUCTURED_API_URL
(CLI) orpartition_endpoint=os.getenv("UNSTRUCTURED_API_URL")
(Python)- The environment variables
UNSTRUCTURED_API_KEY
andUNSTRUCTURED_API_URL
, representing your API key and API URL, respectively.
