## Example

Before using the Solr sink connector, you need to create a configuration file through one of the following methods.

* JSON

  ```json theme={null}
  {
      "solrUrl": "localhost:2181,localhost:2182/chroot",
      "solrMode": "SolrCloud",
      "solrCollection": "techproducts",
      "solrCommitWithinMs": 100,
      "username": "fakeuser",
      "password": "fake@123"
  }
  ```

* YAML

  ```yaml theme={null}
  {
      solrUrl: "localhost:2181,localhost:2182/chroot"
      solrMode: "SolrCloud"
      solrCollection: "techproducts"
      solrCommitWithinMs: 100
