JSON support is available for Redis version 6.2 and above for ElastiCache and MemoryDB in all available regions, at no additional cost. Its often used to improve application performance by reading from a fast in-memory data store instead of a slower disk-based database. You can use this to restore from an ElastiCache snapshot. Only one upgrade operation is performed It is a fixed-size chunk of secure, network-attached RAM. In this post, we show how to easily deploy Amazon ElastiCache for Redis with Terraform. ElastiCache for Redis supports the native JavaScript Object Notation (JSON) format, In-memory data stores enable high-velocity and low-latency workloads with submillisecond latency. All rights reserved. The cluster is available for reads during the entire upgrade and is available for writes for most of the upgrade duration, except during the failover operation which lasts a few seconds. type. GitHub - tmknom/terraform-aws-elasticache-redis: Terraform module which processed before the replicas in other shards are finished Console. Supported browsers are Chrome, Firefox, Edge, and Safari.
