Enabling Remote Streaming in OpenSolr for Drupal Integration

First things first:

Make sure you contact us (or email [email protected]) in order to have remoteStreaming enabled for your Opensolr index. Once we’ve enabled that, you can go ahead and make sure the below stuff is setup correctly in your index. This should work for any index, not just for use with Drupal.

Context

You’re integrating Drupal 10 with OpenSolr and encountering this error:

Remote Streaming is disabled.

—even after setting enableRemoteStreaming="true" inside <requestDispatcher>.

✅ Correct Way to Enable Remote Streaming in OpenSolr

OpenSolr does not rely solely on the <requestDispatcher> setting. While setting this is required, it’s not sufficient.

Here’s the complete step-by-step to get remote PDF indexing via stream.url working:

🔧 Step 1: Ensure Both of These Settings Exist

In your solrconfig.xml:

1.1 Inside `<requestDispatcher>`, this must exist:

<requestDispatcher handleSelect="true">
  <requestParsers enableRemoteStreaming="true" multipartUploadLimitInKB="2048000" />
</requestDispatcher>

1.2 Also, inside the ExtractingRequestHandler, enable this:

Look for this section (or add it if it doesn’t exist):

<requestHandler name="/update/extract" class="solr.extraction.ExtractingRequestHandler">
  <lst name="initParams">
    <bool name="allowRemoteStreaming">true</bool>
  </lst>
</requestHandler>

✅ This is the part that is usually forgotten. Without this, Solr will silently reject stream.url requests with that Remote Streaming is disabled error.

🔁 Step 2: Upload Config to OpenSolr Dashboard

Make sure to:

Edit your Solr config set (either via the OpenSolr dashboard or local files)
Re-upload the entire config set ZIP to your core/index using the OpenSolr Control Panel

🔄 Step 3: Reload or Restart Core

After updating and re-uploading:

Go to OpenSolr Control Panel
Click on your index (59a6fb53f5a58b06f113c1badef132cd)
Click “Reload Core” under the Tools menu

🧪 Step 4: Test It

You can test remote PDF indexing using:

curl "https://host.opensolr.com/solr/<INDEX_NAME>/update/extract?stream.url=https://example.com/sample.pdf&literal.id=test-doc&commit=true"

You should see a 200 OK and no longer get the Remote Streaming is disabled error.
