Why would PaaS providers switch back to offering Redis? They've clearly all already invested a lot in Valkey (AWS, GCP, Heroku).

AWS, GCP, surely are invested: they paid for ValKey, they forked to avoid doing revenue sharing with Redis in any way :D IMHO it's a matter of what the community does, and it, in turn, this depends on how well we are able to develop Redis.

It's not just licensing and hyper-scalers, it's also a matter of development quality and direction. For instance, now in Redis you can find substantial more stuff not available in ValKey, including hash items expires, Vector Sets that are very useful for a number of things, the probabilistic data structures just introduced with Redis 8, and so forth.

If Redis is superior then sticking with Valkey would just be throwing good money after bad. Hopefully those companies are competent enough to understand the concept of sunk costs.

Maybe Valkey has served its purpose in pressuring Redis into playing ball.

Just answering "why would". Whether or not Redis is better then Valkey or if it would be worth it to switch back is not something I know.

AWS and GCP offer valkey-based versions of products that are typically based on Redis, but those versions are currently, generally, preview-grade, and statistically zero customers are using them. They still offer the original, Redis-based versions of those products, which, statistically, 100% of their customers are using.

Do you have data to back up your claims? I see a lot of customer claims for Valkey here, https://aws.amazon.com/elasticache/customers/. Neither of the AWS or GCP offerings are in preview.

>and statistically zero customers are using them

You've said this twice now, but not provided any data or even a hand-wave to a possible source so that others could go get the data and look at it.

If it's statistically something, where are the stats?

>My claim that statistically zero (cloud provider) customers are using valkey should, I sincerely hope, be self-evident.

I have no idea what the actual stats are. But no, I don't find your "statistically 0%" to be self-evident, especially in light of the other comments and links in this thread, and what I've heard elsewhere.

I was hoping, since you presented it so confidently, that you had something more than "trust me". In another comment you say you have evidence of marketshare, maybe you could post that?

Their stats are "I asked an LLM", no, that's not joke, see this thread: https://news.ycombinator.com/item?id=43860256

>Nobody has performed any kind of automatic or default transition from Redis to valkey for existing customers.

>My claim that statistically zero (cloud provider) customers are using valkey should, I sincerely hope, be self-evident.

This is simply not true. For example, Aiven (a cloud provider) completely ended support for Redis at the end of March and migrated existing users to Valkey. https://aiven.io/docs/platform/reference/end-of-life#aiven-f...

I recently moved on to a new company, but my prior company had a pretty large scale Elasticache Redis deployment in production (over 50 large clusters in us-east-1), and were in the middle of a complete migration to Valkey due cost savings, improved performance, and reduction in memory usage.

We've already completed migrating several large production clusters and I can confidently say that the migration had been pretty smooth and seamless.

Valkey is certainly production ready (at least on AWS it is). The team is looking forward to expedite and complete the migration
