+To support InfluxDB 1.x query and write patterns in InfluxDB 2.0, databases and retention
+policies are mapped to buckets using the **database and retention policy (DBRP) mapping service**.
+_See [DBRP mapping](/v2.0/reference/api/influxdb-1x/dbrp/) for more information._

+The InfluxDB v2 API includes InfluxDB 1.x compatibility endpoints that work with
+InfluxDB 1.x client libraries and third-party integrations like [Grafana](https://grafana.com) and others.
+
+## Authentication
+InfluxDB 2.0 requires all query and write requests to be authenticated.
+Use **basic authentication** or **token authentication** to authenticate requests to
+InfluxDB 1.x compatibility endpoints.
+
+### Basic Authentication
+Basic authentications requires the following credentials:
+
+- **username**: InfluxDB username
+- **password**: InfluxDB [authentication token](/v2.0/security/tokens/)
+
+There are multiple ways to provide basic authentication credentials.
+The example below uses the `Authorization` header with the `Basic` scheme to
+provide the required credentials:
+
+##### Basic authentication with authorization header
+```sh
+# Header syntax
+Authorization: Basic <username>:<password>
+
+# Header example
+Authorization: Basic admin:mYSuP3rs3cREtT0k3N
+```
+
+### Token Authentication
+Token authentication requires the following credential:
+
+- **token**: InfluxDB [authentication token](/v2.0/security/tokens/)
+
+Use the `Authorization` header with the `Token` scheme to provide your
+authentication token to InfluxDB.
+
+##### Token authentication with authorization header
+```sh
+# Header syntax
+Authorization: Token <token>
+
+# Header example
+Authorization: Token mYSuP3rs3cREtT0k3N
+```

+---
+
+The InfluxDB 1.x data model includes [databases](https://docs.influxdata.com/influxdb/v1.8/concepts/glossary/#database)
+and [retention policies](https://docs.influxdata.com/influxdb/v1.8/concepts/glossary/#retention-policy-rp).
+InfluxDB 2.0 replaces both with [buckets](/v2.0/reference/glossary/#bucket).
+To support InfluxDB 1.x query and write patterns in InfluxDB 2.0, databases and retention
+policies are mapped to buckets using the **database and retention policy (DBRP) mapping service**.
+
+The DBRP mapping service uses the **database** and **retention policy** specified in
+[compatibility API](/v2.0/reference/api/influxdb-1x/) requests to route operations to a bucket.
+[Create DBRP mappings automatically](#dbrp-mapping-behavior) with the `/write` compatibility endpoint or
+[create DBRP mappings manually](#manually-create-and-manage-dbrp-mappings) using the `/api/v2/dbrps` API endpoint.
+
+- [DBRP mapping behavior](#dbrp-mapping-behavior)
+- [Manually create and manage DBRP mappings](#manually-create-and-manage-dbrp-mappings)
+
+### Default retention policies
+A database can have multiple retention policies with one set as default.
+If no retention policy is specified in a query or write request, InfluxDB uses
+the default retention policy for the specified database.
+
+## DBRP mapping behavior
+
+- [When writing data](#when-writing-data)
+- [When querying data](#when-querying-data)
+
+### When writing data
+When writing data to InfluxDB 2.0 using the [`/write` compatibility endpoint](/v2.0/reference/api/influxdb-1x/write/),
+the DBRP mapping service checks for a bucket mapped to the database and retention policy:
+
+- If a mapped bucket is found, data is written to the bucket.
+- If an unmapped bucket with a name matching:
+    - **database/retention policy** exists, a DBRP mapping is added to the bucket,
+      and data is written to the bucket.
+    - **database** exists (without a specified retention policy), the default
+      database retention policy is used, a DBRP mapping is added to the bucket,
+      and data is written to the bucket.
+- If no matching bucket is found, a new **database/retention-policy** bucket is
+  created with a DBRP mapping, and data is written to the bucket.
+  If no retention policy is specified, `autogen` is used.
+
+    {{% note %}}
+To automatically create new buckets, the authentication token used for the
+write request must be an **All Access token**.
+    {{% /note %}}
+
+### When querying data
+When querying data from InfluxDB 2.0 using the [`/query` compatibility endpoint](/v2.0/reference/api/influxdb-1x/query/),
+the DBRP mapping service checks for the specified database and retention policy
+(if no retention policy is specified, the database's default retention policy is used):
+
+- If a mapped bucket exists, data is queried from the mapped bucket.
+- If no mapped bucket exists, InfluxDB returns an error.
+
+## Manually create and manage DBRP mappings
+If you have an existing bucket that does't follow the **database/retention-policy**
+naming convention, you **must** manually create a database and retention policy
+mapping to query that bucket with the `/query` compatibility API.
+Use the using the [`/api/v2/dbrps` API endpoint](/v2.0/api/#tag/DBRPs) to
+manually create and manage DBRP mappings.
+
+**To manually create a DBRP mapping, provide the following:**
+
+- authentication token
+- organization name or ID
+- target bucket ID
+- database to map
+- retention policy to map
+
+<!--  -->
+```sh
+curl -XPOST https://cloud2.influxdata.com/api/v2/dbrps \
