| You could add the following config to `elasticsearch.yml`, and set the value based on your environment variable. |
| ```yml |
| # In the case of tracing, consider setting a value higher than this. |
| thread_pool.index.queue_size: 1000 |
| thread_pool.write.queue_size: 1000 |
| |
| # When you face query error at trace page, remember to check this. |
| index.max_result_window: 1000000 |
