## Change the plan [#change-the-plan]

On the database's **Settings** tab, under **Plan**, pick a bigger or smaller plan and select **Change
plan**. Memory and CPU change live, without a restart, and billing follows the new plan from then on.

## Eviction and persistence [#eviction-and-persistence]

Change the **Eviction policy** and **Persistence** on **Settings**, then **Save settings**. Changes apply
live, without a restart. See [Create a Redis database](/en/data-storage/redis/create-a-redis-database)
for what each option does.

## Metrics [#metrics]

The **Overview** shows memory use from the last hour; the **Metrics** tab charts, for the last hour, 24
hours or 7 days:

* **Memory used** against the plan's limit;
* **Operations / s**: commands processed per second;
* **Hit rate**: reads that found their key;
* **Connected clients**;
* **Evictions**: keys removed to free memory;
* **Keys** stored;
* **CPU** in use.

When memory is nearly full, the Overview warns you: with an eviction policy, keys are being evicted to make
room; with `noeviction`, writes fail. Move to a bigger plan to keep more.

## Delete the database [#delete-the-database]

On **Settings**, select **Delete database** and confirm. Its data is removed and billing stops. This can't
be undone.
