Read and write data to the cache - Amazon ElastiCache

Read and write data to the cache

This section assumes that you've created an Amazon EC2 instance and can connect to it. For instructions on how to do this, see the Amazon EC2 Getting Started Guide.

This section also assumes that you have setup VPC access and security group settings for the EC2 instance from where you are connecting to your cache, and setup valkey-cli on your EC2 instance. For more information on that step see Setting up ElastiCache.

Find your cache endpoint

AWS Management Console

To find your cache’s endpoint using the ElastiCache console:

  1. Sign in to the AWS Management Console and open the Amazon ElastiCache console at https://console.aws.amazon.com/elasticache/.

  2. In the navigation pane on the left side of the console, choose Valkey caches Redis OSS caches.

  3. On the right side of the console, click on the name of the cache that you just created.

  4. In the Cache details, locate and copy the cache endpoint.

AWS CLI

The following AWS CLI example shows to find the endpoint for your new cache using the describe-serverless-caches command. Once you have run the command, look for the "Endpoint" field.

Linux

aws elasticache describe-serverless-caches \
		--serverless-cache-name CacheName

Windows

aws elasticache describe-serverless-caches ^
		--serverless-cache-name CacheName

Now that you have the endpoint you need, you can log in to your EC2 instance and connect to the cache. In the following example, you use the valkey-cli utility to connect to a cluster. The following command connects to a cache (note: replace cache-endpoint with the endpoint you retrieved in the previous step).

src/valkey-cli -h cache-endpoint --tls -p 6379
set a "hello"          // Set key "a" with a string value and no expiration
OK
get a                  // Get value for key "a"
"hello"

Now that you have the endpoint you need, you can log in to your EC2 instance and connect to the cache. In the following example, you use the valkey-cli utility to connect to a cluster. The following command connects to a cache. Open the Command Prompt and change to the Valkey directory and run the command (note: replace Cache_Endpoint with the endpoint you retrieved in the previous step).

c:\Redis>valkey-cli -h Redis_Cluster_Endpoint --tls -p 6379
set a "hello"          // Set key "a" with a string value and no expiration
OK
get a                  // Get value for key "a"
"hello"

You may now proceed to (Optional) Clean up.
