-If you require more control over `RedisCacheManager` e.g. set _time to live_ for the particular caches, you can customize `org.springframework.data.redis.cache.RedisCacheManager$RedisCacheManagerBuilder`
-programmatically by declaring `RedisCacheManagerBuilderCustomizer` bean(s) as shown in the following example:
+NOTE: By default, a key prefix is added so that, if two separate caches use the same key, Redis does not have overlapping keys and cannot return invalid values.
+We strongly recommend keeping this setting enabled if you create your own `RedisCacheManager`.

+TIP: You can take full control of the default configuration by adding a `RedisCacheConfiguration` `@Bean` of your own.
+This can be useful if you're looking for customizing the default serialization strategy.

+If you need more control over the configuration, consider registering a `RedisCacheManagerBuilderCustomizer` bean.
+The following example shows a customizer that configures a specific time to live for `cache1` and `cache2`:
