| description: |- | ||
| D1 now detects read-only queries and automatically attempts up to two retries to execute those queries in the event of failures with retryable errors. You can access the number of execution attempts in the returned [response metadata](/d1/worker-api/return-object/#d1result) property `total_attempts`. | ||
| At the moment, only read-only queries are retried, that is, queries containing only the following SQLite keywords: `SELECT`, `EXPLAIN`, `WITH`. Queries containing any [SQLite keyword](https://sqlite.org/lang_keywords.html) that leads to database writes are not retried. |

| Latency improvements range from 50-500 ms depending on request location and [database location](/d1/configuration/data-location/) and only apply to the REST API. REST API requests and databases outside the United States see a bigger benefit since Cloudflare's primary core data centers reside in the United States. | ||
| D1 query endpoints like `/query` and `/raw` have the most noticeable improvements since they no longer access Cloudflare's core data centers. D1 control plane endpoints such as those to create and delete databases see smaller improvements, since they still require access to Cloudflare's core data centers for other control plane metadata. |
