+## Disclaimer
+
+The Couchbase Columnar data source does not achieve full test coverage.
+Please do not assume complete stability.

+```
+
+The full set of configuration options is available [here](https://rtd.feast.dev/en/master/#feast.infra.offline_stores.contrib.couchbase_offline_store.couchbase_source.CouchbaseColumnarSource).
+
+## Supported Types
+
+Couchbase Capella Columnar data sources support `BOOLEAN`, `STRING`, `BIGINT`, and `DOUBLE` primitive types.

+# Couchbase Columnar offline store (contrib)
+
+## Description
+
+The Couchbase Columnar offline store provides support for reading [CouchbaseColumnarSources](../data-sources/couchbase.md). **Note that Couchbase Columnar is available through [Couchbase Capella](https://cloud.couchbase.com/).**
+* Entity dataframes can be provided as a SQL++ query or can be provided as a Pandas dataframe. A Pandas dataframe will be uploaded to Couchbase Capella Columnar as a collection.
+
+## Disclaimer
+
+The Couchbase Columnar offline store does not achieve full test coverage.
+Please do not assume complete stability.
+
+## Getting started
+
+In order to use this offline store, you'll need to run `pip install 'feast[couchbase]'`. You can get started by then running `feast init -t couchbase`.
+
+To get started with Couchbase Capella Columnar:
+1. Sign up for a [Couchbase Capella](https://cloud.couchbase.com/) account
+2. [Deploy a Columnar cluster](https://docs.couchbase.com/columnar/admin/prepare-project.html)
+3. [Create an Access Control Account](https://docs.couchbase.com/columnar/admin/auth/auth-data.html)
+    - This account should be able to read and write. 
+    - For testing purposes, it is recommended to assign all roles to avoid any permission issues.
+4. [Configure allowed IP addresses](https://docs.couchbase.com/columnar/admin/ip-allowed-list.html)
+    - You must allow the IP address of the machine running Feast.
+
+
+## Example
+
+{% code title="feature_store.yaml" %}
+```yaml
+project: my_project
+registry: data/registry.db
+provider: local
+offline_store:
+  type: couchbase.offline
+  connection_string: COUCHBASE_COLUMNAR_CONNECTION_STRING # Copied from Settings > Connection String page in Capella Columnar console, starts with couchbases://
+  user: COUCHBASE_COLUMNAR_USER # Couchbase cluster access name from Settings > Access Control page in Capella Columnar console
+  password: COUCHBASE_COLUMNAR_PASSWORD # Couchbase password from Settings > Access Control page in Capella Columnar console
+  timeout: 120 # Timeout in seconds for Columnar operations, optional
+online_store:
+    path: data/online_store.db
+```
+{% endcode %}
+
+Note that `timeout`is an optional parameter.
+The full set of configuration options is available in [CouchbaseColumnarOfflineStoreConfig](https://rtd.feast.dev/en/master/#feast.infra.offline_stores.contrib.couchbase_offline_store.couchbase.CouchbaseColumnarOfflineStoreConfig).
