IngestDocument​Ingest​Document

Ingest documents into an embedding store.

Only text documents (TXT, HTML, Markdown) are supported for now.

yaml
type: "io.kestra.plugin.langchain4j.rag.IngestDocument"

Ingest documents into a KV embedding store.\nWARNING: the KV embedding store is for quick prototyping only, as it stores the embedding vectors in a K/V Store and load them all in memory.

Properties

Embedding Store Provider

Language Model Provider

This provider must be configured with an embedding model.

The document splitter

Default false

Whether to drop the store before ingestion. Useful for testing purpose.

A list of inline documents

SubType string

A list of document URLs from external sources

SubType string

A list of internal storage URIs representing documents

A path inside the task working directory that contains documents to ingest

Each document inside the directory will be ingested into the embedding store. This is recursive and protected from being path traversal (CWE-22).

SubType string

Additional metadata that will be added to all ingested documents

Additional outputs from the embedding store.

The number of ingested documents

The input token count

The output token count

The total token count

Endpoint URL

Project location

Model name

Project ID

API endpoint

The Azure OpenAI endpoint in the format: https://{resource}.openai.azure.com/

Model name

API Key

Client ID

Client secret

API version

Tenant ID

API Key

Model name

Default https://api.deepseek.com/v1

API base URL

SubType string
Min items 1

List of HTTP ElasticSearch servers.

Must be an URI like https://elasticsearch.com: 9200 with scheme and port.

Basic auth configuration.

SubType string

List of HTTP headers to be send on every request.

Must be a string with key value separated with : , ex: Authorization: Token XYZ.

Sets the path's prefix for every request used by the HTTP client.

For example, if this is set to /my/path, then any client request will become /my/path/ + endpoint. In essence, every request's endpoint is prefixed by this pathPrefix. The path prefix is useful for when ElasticSearch is behind a proxy that provides a base path or a proxy that requires all paths to start with '/'; it is not intended for other purposes and it should not be supplied in other scenarios.

Whether the REST client should return any response containing at least one warning header as a failure.

Trust all SSL CA certificates.

Use this if the server is using a self signed SSL certificate.

API Key

Model name

API Key

Model name

API base URL

Model endpoint

Model name

Basic auth password.

Basic auth username.

Default {{flow.id}}-embedding-store

The name of the K/V entry to use

API Key

Model name

AWS Access Key ID

Model name

AWS Secret Access Key

Default COHERE
Possible Values
COHERETITAN

Amazon Bedrock Embedding Model Type

The content of the document

The metadata of the document

The database name

The database server host

The database password

The database server port

The table to store embeddings in

The database user

Default false

Whether to use use an IVFFlat index

An IVFFlat index divides vectors into lists, and then searches a subset of those lists closest to the query vector. It has faster build times and uses less memory than HNSW but has lower query performance (in terms of speed-recall tradeoff).

API Key

Model name

API base URL

The maximum size of the overlap, defined in characters. Only full sentences are considered for the overlap.

The maximum size of the segment, defined in characters.

Default RECURSIVE
Possible Values
RECURSIVEPARAGRAPHLINESENTENCEWORD

Title the type of the DocumentSplitter

We recommend using a RECURSIVE DocumentSplitter for generic text. It tries to split the document into paragraphs first and fits as many paragraphs into a single TextSegment as possible. If some paragraphs are too long, they are recursively split into lines, then sentences, then words, and then characters until they fit into a segment.

The name of the index to store embeddings
