Supported connectors

OpenSearch provides two types of connector blueprints:

  • Standard blueprints (recommended for OpenSearch 2.14+):

    • Designed for connectors that pass input directly to the model and return its raw output without requiring additional transformations.
    • Use a registered model without any pre-processing or post-processing functions.
    • Compatible with machine learning (ML) inference processors: ingest processors, search request processors, and search response processors.
    • Ideal for new implementations in OpenSearch 2.14 and later.

  • Legacy blueprints:

    • Suitable for specific input and output formatting requirements.
    • Include pre- and post-processing functions.
    • Recommended for existing implementations.
    • Compatible with neural search queries.

The following table provides a comprehensive list of connector blueprints available in OpenSearch. Each blueprint link offers an example request for creating the connector, including all necessary parameters, and a sample Predict API request.
