Hi, Wayne Gao Thanks a lot for starting this thread and also happy to see more storage related projects in the ASF.
I have two questions around this idea: - The ASF advocates Community Over Code. In the incubator, we help projects grow and mature their communities, rather than just building a code repository. So where is your community? Are there any outside contributors besides Solidigm? - The ASF works for public good. If your code is already part of upstream SPDK, why do you believe donating it to the ASF will improve things? Are you considering open-sourcing your internal closed-source projects as well? Does this software work with all SSDs or just Solidigm ones?
