If an external contributor were to bring such features to the open source redis, would they refuse it?

[darkhorse13]

Probably won't be able to refuse it outright. Though It's unlikely that an external contributor would be able to bring these features in easily. Redis Labs has a lot of people working on their enterprise offering.

Redis has sentinel and scaling features, as well as established patterns. Enterprises are likely willing to pay for experience of doing it right, reliably.

Not all of the value they provide can be replaced by a pull request.

That said, theres equal if not greater motivation for this hypothetical contributor to raise their own $100mm and compete with Redis Labs.

[rad_gruchalski]

Most likely.
