# Edge Storage
Edge Storage allows you to store key-value pairs across our global edge network, providing super-fast, high-volume read capability.
## Creating Edge Storage
1\. In the [Gcore Customer Portal](https://portal.gcore.com/accounts/reports/dashboard), navigate to **FastEdge** and choose the relevant page: **Edge Storage**.
2\. In the top-right corner of the screen, click **Add Edge Storage**.
3\. Enter a name for your Edge Storage and provide a description if needed.
4\. Click **Create Edge Storage**. (This completes the Edge Storage creation step)
5\. Proceed with inserting key-value pairs.
## Inserting KV pairs
#### 1. Add a key-value pair.
Click **Insert item** and select **KV Pair**.
In the side panel insert as many KV pairs as you need.
Click **+ Add value** to get another entry row.
#### 2. Upload a value from a file.
Click the **Upload Icon** to add a value from file. This can be text and/or binary files (e.g. images / fonts etc..)
**Info**
Uploading values from file has a 1 MB file size limit. Keys are limited to 256 bytes.
**Note**:
File uploads will transform the value in the UI Portal to a hash representation of its content.
#### 3. Add a value with an expiration date.
Click the **Expiry Icon** to add a value with an expiration date/time.
**Info**
These values will stop being available in the runtime, after the expiration date. They may remain visible in the UI Portal for longer.
## Editing KV pairs
1\. In the [Gcore Customer Portal](https://portal.gcore.com/accounts/reports/dashboard), navigate to **FastEdge** and choose the relevant page: **Edge Storage**.
2\. Find the Edge Storage you want to edit and click its name to open it.
3\. Find the key-value pair you want to edit, click the three-dot icon next to the key-value, and select edit.
4\. You are now able to edit its value and/or provide an expiration date. If everything is configured correctly, click **Save**.
**Note**
You can also insert more key-value pairs from this page. Duplicate keys overwrite the existing value.
## Deleting KV pairs
1\. In the [Gcore Customer Portal](https://portal.gcore.com/accounts/reports/dashboard), navigate to **FastEdge** and choose the relevant page: **Edge Storage**.
2\. Find the Edge Storage you want to edit and click its name to open it.
3\. Find the key-value pair you want to delete, click the three-dot icon next to the key-value, and select delete.
4\. Confirm you want to delete the key-value pair.
## Bulk deleting KV pairs
1\. In the [Gcore Customer Portal](https://portal.gcore.com/accounts/reports/dashboard), navigate to **FastEdge** and choose the relevant page: **Edge Storage**.
2\. Find the Edge Storage you want to edit and click its name to open it.
3\. Find all the key-value pairs you want to delete, selecting their checkbox in the first column.
4\. Click **Group actions** and select **Delete all**.
5\. Confirm you want to delete all the key-value pairs.
## Accessing Edge Storage in applications
For more information regarding Edge Storage usage in applications see the [JavaScript SDK](https://g-core.github.io/FastEdge-sdk-js/reference/fastedge/kv/open/) and the [Rust SDK](https://docs.rs/fastedge/latest/fastedge/key_value/struct.Store.html)
**Info**
In order to use Edge Storage in an application it must first be linked to the application. See [Managing Application - Edge Storage](/fastedge/manage-apps#edge-storage)
## BYOD (Bring Your Own Data)
Edge Storage provides the ability to connect your own external key-value database.
To create a store with your own data:
1\. In the [Gcore Customer Portal](https://portal.gcore.com/accounts/reports/dashboard), navigate to **FastEdge** and choose the relevant page: **Edge Storage**.
2\. In the top-right corner of the screen, click **Add Edge Storage**.
3\. Enter a name for your Edge Storage and provide a description if needed.
4\. Check the BYOD checkbox and provide your database connection URL.
**Info**
During the creation of the Edge Storage the server will attempt to connect to this database. Edge Storage creation will fail if a connection cannot be made.
5\. If everything is configured correctly, click **Create Edge Storage**.
**Warning**
When creating Edge Storage, you cannot change between BYOD and hosted storage. Once you have created a store it can no longer be updated to change its type.
