2022/11/03 - Amazon MemoryDB - 10 updated api methods
Changes Adding support for r6gd instances for MemoryDB Redis with data tiering. In a cluster with data tiering enabled, when available memory capacity is exhausted, the least recently used data is automatically tiered to solid state drives for cost-effective capacity scaling with minimal performance impact.
