2017年9月15日 · The AWS::ElastiCache::ReplicationGroup resource creates an Amazon ElastiCache Redis replication group. A replication group is a collection of cache clusters, where one of the clusters is a primary read-write cluster and the others are read-only replicas.

2016年5月10日 · I just rebooted my Redis Elasticache node, and the cache maintained through reboot. Only thing that worked for me using redis-cli and FLUSHALL, from answer below. – pendo

For e.g., go-redis/redis or garyburd/redigo. In short, use the AWS SDK to manage your ElastiCache infrastructure and Redis' Go clients to put or get items from the cache.

2019年10月12日 · The redis also can use aws_elasticache_cluster but only if when redis has node 1, that is not a cluster mode. num_cache_nodes – (Required unless replication_group_id is provided) The initial number of cache nodes that the cache cluster will have.

2015年1月4日 · As of Feb 2016, AWS allows using lambda functions to connect to Elasticache. Refer to Access Resources within a VPC using AWS Lambda. Here is a link how it works - Tutorial: Configuring a Lambda Function to Access Amazon ElastiCache in an Amazon VPC

To me these two options seem to achieve the same outcome for me - which is to reduce load on my master database, but I am thinking I may have understood some fundamentals wrongly because Google doesnt seem to return any results on a comparison between them.

engine = "redis" subnet_group_name = aws_elasticache_subnet_group.redis.name security_group_ids = concat(var.security_group_ids, [aws_security_group.redis.id]) } Your subnet group basically includes all private or public subnets from your VPC where the elasticache replication group is going to be created.

2019年4月24日 · I have created a Redis Elasticache cluster in AWS and would like to read and write data to the cluster using Python script which will eventually become a Lambda function. I've read that the typical way to connect to the cluster is EC2. I have setup an EC2 instance and connected to it successfully using SSH and key pair. My questions are:
