## Vector Search

### Does ScyllaDB Cloud support Vector Search?

Yes. ScyllaDB Cloud includes built-in
[Vector Search](https://cloud.docs.scylladb.com/stable/vector-search/index.md), allowing you to store, index, and
query high-dimensional vector data for AI and machine learning workloads
such as semantic search, RAG, and recommendation systems. Vector Search is
available on Standard, X Cloud, and free trial clusters running ScyllaDB
2025.4.3 or later.

See the [Vector Search Quick Start](https://cloud.docs.scylladb.com/stable/vector-search/vector-search-quick-start.md)
to get started, or consult the [Vector Search FAQ](https://cloud.docs.scylladb.com/stable/vector-search/vector-search-faq.md)

quantization, and more.

### How can I enable experimental features for ScyllaDB Cloud?

ScyllaDB Cloud does not support experimental features. The service deploys the latest ScyllaDB version with
experimental features disabled.

### How can I enable DNS names for my cluster nodes?

If you create a new cluster, DNS names are already enabled, and no action is required from you. DNS names are automatically
generated by ScyllaDB and may resemble the following: `node-0.aws_us_east_1.5493c518df7fdc22b724.clusters.scylla.cloud`.

For existing clusters, you may need to manually enable DNS names in your cluster’s view:

1. Go to the **General** tab.
2. Click the **Enable** button next to “DNS”.
3. Wait for the DNS feature to be enabled. The time to complete this process may vary, depending on your cluster size.

Using DNS names eliminates the need to update the IP in the connection strings when there’s a change in the cluster,
for example, when a node is replaced. In such cases, the node’s DNS name remains unchanged, sparing you the time and
effort to update your application and drivers.

### How can I set custom tags to my AWS resources?

AWS tags are metadata that help you identify and manage your resources. A tag consists of a key and value; see
[Tagging AWS resources](https://docs.aws.amazon.com/general/latest/gr/aws_tagging.html) for more information.

To assign custom tags to your AWS resources in a ScyllaDB Cloud cluster, open a support [ticket](https://cloudsupportscylla.zendesk.com/hc/en-us)
providing the requested key-value pairs:

Subject: *Set AWS custom tags*

*Please set the following tags:*

```console
Cluster: <ID>
Key: <service/group/resource name>, value: <some UUID>
Key: <service/group/resource name>, value: <some UUID>
```

For example:

```console
Clusters:  12233, 112234
Key: App_ID, value: 5ff91777
Key: Owner, value: TeamFrontend
```
