问题 Is there any way to access cache nodes from local development environment? Although the same cache nodes are accessible from EC2 instance. I'm using Enyim memcache client library with C#. I found few article saying this is not possible then what should be best approach. Should i need to setup memcache locally for development work? 回答1: When you create your Elastic Cache cluster, you have to define a Security Group. A Security group is a set of rules that define what IP addresses are

问题 Is there a way to connect to the Redis Cache Cluster Node by providing the Node endpoint? Which library should I use for this? Also, which API should I use to store and retrieve contents from the Cache? 回答1: In short It depends. Explanation You can connect to Redis Cluster nodes without command dispatching to other nodes. You just should make sure, that you access keys that are handled by the node. If you are connecting to a slave make sure, that your connection is in READONLY mode, otherwise

问题 I'm confused as to how to connect to AWS's ElastiCache Redis via Node.js. I've successfully managed to connect to the primary host (001) via the node_redis NPM, but I'm unable to use the clustering ability of ioredis because apparently ElastiCache doesn't implement the CLUSTER commands. I figured that there must be another way, but the AWS SDK for Node only has commands for managing ElastiCache, not for actually connecting to it. Without using CLUSTER, I'm concerned that my app won't be able

问题 I am using AWS Elasticache and here is the method I am using with annotation, @Cacheable(unless = "#result != null and #result.size() == 0") public List<SomeObject> findById(String id) { return dynamoDBMapper.query(SomeObject.class, queryExpression(id)); } Here is my query expression, DynamoDBQueryExpression<SomeObject> queryExpression(String id) { SomeObject object = new SomeObject(); object.setId(id); return new DynamoDBQueryExpression<SomeObject>() .withIndexName("idIndex")

问题 My problem is that I do not think I am able to refresh the magento redis cache from the admin page. I realize that the problem could come from many sources, but my gut tells me it has something to do with the backend being on a separate server. My magento installation is as follows: Magento CE 1.8 Backend server and NFS(media) on an Amazon AWS EC2 at http://admin.example.com Database on AWS RDS MySQL 2 app servers (scalable to more) on AWS Elastic Beanstalk at http://www.example.com (route53)

问题 I have a Redis cluster running on ElastiCache. Multiple processes connect to the Redis cluster. Each process lives within a Docker container. The processes are not all the same -- I have a web process, a worker process, etc. After a few days of operating normally, some of my web processes begin to time out when connecting to Redis. When I ssh into an affected web container and try to reach the cluster via redis-cli , my connection to the cluster times out. This tells me that the issue affects

问题 I've searched and searched and have been unable to find a tutorial / example / walkthrough with all of the above! I am trying to write a Lambda function in C# which makes use of some ElastiCache storage. I can find examples of ElastiCache access from C#, but every Library I have found referenced will not operate with .NetCore 1.0, which is what Lambda uses! Has anyone managed to do this? Many thanks. 回答1: Yes, it is possible and you're right, the information on this subject is sparse. The key

问题 I was trying to setup Elastic cache (memcached engine) & use in my .NET application through a memcache c# client API "Enyim". I'm new to AWS and facing some problems. I have few questions :- Question 1 : Can I access my cache cluster nodes from my local machine ? Question 2 : What is the process of setting up complete AWS Elastic cache instance. Correct me if i'm wrong :- Setup VPC (by default) Setup a security group in EC2 (by default) Setup cache cluster as with same VPC. Now how can i use

问题 I've a redis server set with a maxmemory-policy set to volatile-lru . The documentation indicate this will evict from the set of entries with expires set when memory limit has reached. In this case, does redis only evict items past their expiration? If everything in memory has an expire set, but nothing is past the expiration time, will anything get evicted when max memory is reached? 回答1: If your eviction policy is set to any of the volatile-* policies, when running out of memory and having

问题 According to Elasticache manual, the SLAVEOF command is restricted for AWS cache nodes. Is there anyway to set an existing Elasticache node as a slave so that I can migrate my existing redis cluster over to AWS? 回答1: As you've spotted, Elasticache doesn't support the SLAVEOF command so you can't simply add an Elasticache node to your existing cluster and then promote it to the primary node/switch off your existing cluster. Instead, to migrate your Redis cluster you should create a snapshot by
