The Meilisearch sink indexes documents into a Meilisearch index, using the Meilisearch JSON API.

​
Configuration

  • Endpoint URL

    The URL of your Meilisearch server (e.g., http://localhost:7700 or https://your-meilisearch-instance.com).

  • Index name

    The name of the Meilisearch index where documents will be indexed. The index must exist before imports can work.

  • Primary key

    The primary key field for the Meilisearch index. (By default, this is id)

  • API key

    The API key for authenticating with your Meilisearch server.

​
Transform requirements

Your transform must return a document matching the schema of the Meilisearch index.

For example, the following transform ensures the primary key (id) is at the top level of the returned map:

def transform(action, record, changes, metadata) do
  Map.put(record, "id", Kernel.to_string(record["product"]["id"]))
end

​
Import action

Sequin uses Meilisearch’s documents API to create or update documents:

  • Meilisearch will create a new document or update an existing one based on the id.

​
API endpoints used by Sequin

Sequin uses the following endpoints of the Meilisearch Documents API:

  • PUT /indexes/{index_uid}/documents
    For indexing batches of documents or single documents. Meilisearch accepts both.

  • POST /indexes/{index_uid}/documents/delete-batch
    For batch deleting documents.

Sequin also uses one method of the Indexes API:

  • GET /indexes/{index_uid}
    Only called when you click “Test Connection” in the Sequin console.
    Successful responses indicate the connection is working and the index exists, but the result is otherwise ignored.

Sequin does not perform any searches.

​
Routing

The Meilisearch sink supports dynamic routing of the index_name with routing functions.

Example routing function:

def route(action, record, changes, metadata) do
  %{
    index_name: metadata.table_name
  }
end

When not using a routing function, documents will be written to the index specified in the sink configuration.

​
Error handling

Common errors that can occur when working with the Meilisearch sink include:

  • Connection issues to the Meilisearch server (HTTP vs HTTPS, TCP port, URL typos, etc.)
  • Schema mismatches
  • Missing primary key fields

When errors occur, they will be visible in the “Messages” tab of the Sequin web console. You can click on a message to see details about the error.
Error messages from the Meilisearch API are passed through unchanged to the Sequin console, including messages for asynchronous batch imports.
