Feature/reindex support 321

[ljluestc]

We expose the Elasticsearch _reindex API via a new HTTP endpoint on the status server. This allows for triggering manual reindexing operations directly.

Usage

To trigger a reindex, send a POST request to the /reindex endpoint of the status server (default port 12800). The body of the request should contain the standard Elasticsearch reindex JSON payload.

Example

curl -X POST http://127.0.0.1:12800/reindex -d '{
  "source": {
    "index": "old_index"
  },
  "dest": {
    "index": "new_index"
  }
}'

Implementation Details

The implementation involves:

• Elasticsearch Client: A Reindex method has been added to the internal client.
• HTTP Handler: A new handler /reindex accepts JSON requests and proxies them to the Elasticsearch _reindex API.
