Embedding
Embedding Transform Plugin
Description
The Embedding transform plugin leverages embedding models to convert text data into vectorized representations. This
transformation can be applied to various fields. The plugin supports multiple model providers and can be integrated with
different API endpoints.
Options
| Name | Type | Required | Default Value | Description |
|---|---|---|---|---|
| model_provider | enum | yes | - | The model provider for embedding. Options may include QIANFAN, OPENAI, etc. |
| api_key | string | yes | - | The API key required to authenticate with the embedding service. |
| secret_key | string | yes | - | The secret key required for additional authentication with the embedding service. |
| single_vectorized_input_number | int | no | 1 | The number of inputs vectorized in one request. Default is 1. |
| vectorization_fields | map | yes | - | A mapping between input fields and their corresponding output vector fields. |
| model | string | yes | - | The specific model to use for embedding (e.g: text-embedding-3-small for OPENAI). |
| api_path | string | no | - | The API endpoint for the embedding service. Typically provided by the model provider. |
| oauth_path | string | no | - | The API endpoint for the oauth service. |
| custom_config | map | no | Custom configurations for the model. | |
| custom_response_parse | string | no | Specifies how to parse the response from the model using JsonPath. Example: $.choices[*].message.content. | |
| custom_request_headers | map | no | Custom headers for the request to the model. | |
| custom_request_body | map | no | Custom body for the request. Supports placeholders like ${model}, ${input}. |
model_provider
The providers for generating embeddings include common options such as DOUBAO, QIANFAN, and OPENAI. Additionally,
you can choose CUSTOM to implement requests and retrievals for custom embedding models.
api_key
The API key for authenticating requests to the embedding service. This is typically provided by the model provider when you register for their service.
secret_key
The secret key used for additional authentication. Some providers may require this for secure API requests.
single_vectorized_input_number
Specifies how many inputs are processed in a single vectorization request. The default is 1. Adjust based on your processing capacity and the model provider's API limitations.
vectorization_fields
A mapping between input fields and their respective output vector fields. This allows the plugin to understand which text fields to vectorize and how to store the resulting vectors.
vectorization_fields {
book_intro_vector = book_intro
author_biography_vector = author_biography
}
model
The specific embedding model to use. This depends on the embedding_model_provider. For example, if using OPENAI, you
might specify text-embedding-3-small.
api_path
The API endpoint to use for making requests to the embedding service. This might vary based on the provider and model used. Generally, this is provided by the model provider.
oauth_path
The API endpoint for the oauth service. Get certification information. This might vary based on the provider and model used. Generally, this is provided by the model provider.
custom_config
The custom_config option allows you to provide additional custom configurations for the model. This is a map where you
can define various settings that might be required by the specific model you're using.
custom_response_parse
The custom_response_parse option allows you to specify how to parse the model's response. You can use JsonPath to
extract the specific data you need from the response. For example, by using $.data[*].embedding, you can extract
the embedding field values from the following JSON and obtain a List of nested List results. For more details on
using JsonPath, please refer to
the JsonPath Getting Started guide.

}
}
custom_request_headers
The custom_request_headers option allows you to define custom headers that should be included in the request sent to
the model's API. This is useful if the API requires additional headers beyond the standard ones, such as authorization
tokens, content types, etc.
custom_request_body
The custom_request_body option supports placeholders:
${model}: Placeholder for the model name.${input}: Placeholder to determine input value and define request body request type based on the type of body value. Example:["${input}"]-> ["input"] (list)

Melville’s work is known for its complexity, symbolism, and exploration of themes such as man’s place in the universe, the nature of evil, and the quest for meaning. Despite facing financial difficulties and critical neglect during his lifetime, Melville’s reputation soared posthumously, and he is now considered one of the great American authors."
