What is an ElastiCache parameter group?

A parameter group is a collection of Redis configuration values that you apply to your ElastiCache cluster. You cannot modify the default parameter group, so you create a custom one with your desired settings. Changes to some parameters require a reboot to take effect.

Which maxmemory-policy should I use?

For general caching, allkeys-lru is usually best as it evicts the least recently used keys when memory is full. For caching with TTL-based expiration, volatile-lru only evicts keys with an expiration set. For session stores where you do not want eviction, use noeviction and ensure sufficient memory.

About This Tool

The ElastiCache Redis Config Generator helps you build optimal Redis configuration parameters for Amazon ElastiCache. Redis has dozens of configuration parameters that affect memory management, persistence, eviction policies, and replication behavior. This tool provides guided configuration based on your use case (caching, session store, message queue) and cluster size, generating ElastiCache parameter group settings with explanations for each value.

When to Use This Tool

•Generate optimal Redis configuration for a caching layer with appropriate maxmemory-policy, eviction settings, and timeout values.
•Configure Redis parameter groups for session storage with proper persistence and backup settings.
•Build configuration for a Redis-based message queue with keyspace notifications and list-related tuning parameters.
•Compare configuration options for different ElastiCache node types to balance memory, CPU, and network performance.
