I run Redis across dozens of applications. So when Valkey became available for a discounted price on AWS I was excited. We finally got around to trying it out about 2 months ago and all was going well. No noticeable difference in performance. Until Valkey just died. It died in such a way that AWS still thought it was running happily but it was completely offline. It took 12+ hours for it to come up again and then it happened again... AWS researched the issue for 2 weeks and couldn't figure it out. It will be a long time before we attempt to use Valkey for anything critical in the future. We since have replace that Valkey with Redis under the same workload and have no issues.
