# Working with large keyspaces
|
||
|
||
## Use specific `SCAN` filter to reduce loaded amount of keys
|
||
|
||
|
||
By default RESP.app uses `*` (wildcard glob-style pattern) in `SCAN` command to load all keys from the selected database. It’s simple and user-friendly for cases when you have only a couple of thousands keys. But for production redis-servers with millions of keys it leads to a huge amount of time needed to load keys in RESP.app.
|
||
|
||
However, while working with production redis-servers that contain millions of keys users have to wait for a long time till all keys are loaded.
|
||
|
||
Consider using more specific filters for `SCAN` in order to speed up keys loading and reduce memory footprint
|
||
|
||
1. Right click on database and click on Filter button <br> <img width="250" src="https://user-images.githubusercontent.com/1655867/91542521-aa18c300-e926-11ea-8f09-4a0322d0f9ee.png">
|
||
2. Enter glob-style pattern and press apply button <br> <img width="250" src="https://user-images.githubusercontent.com/1655867/91542549-b4d35800-e926-11ea-9920-ca0ad8701c56.png">

More details about `SCAN` filter syntax you can find in Redis documentation https://redis.io/commands/scan#the-match-option
|
||
|
||
|
||
Default `SCAN` filter can be changed in connection settings on “Advanced Settings” tab:

## Use namespaced keys
|
||
|
||
Colon sign `:` is a commonly used convention when naming Redis keys. For example you can use following schema to store information about users:
|
||
|
||
`user:1000`
|
||
|
||
Following this schema allows you to simplify removal of obsolete keys and performing other operations with keys in Redis.
|
||
|
||
Using namespaced keys is also important for loading huge keyspaces in RESP.app. It renders namespaces on demand (since 2020.2+) and this approach allows to visualise millions of keys with small memory footprint.

Default namespace separator can be changed in connection settings on “Advanced Settings” tab.
