Hi, Sergey! Yes, that's basically how I fixed it. But only in key_rec_cmp(), key_cmp() changes somehow weren't needed. Perhaps they'll be needed for range optimizer though. Please, use preview-10.8-MDEV-26938-desc-indexes for your range optimizer work. On Dec 11, Sergey Petrunia wrote:

I've hit this again when trying to get range optmizer to work. Please find the patch below. It follows MySQL-8's approach.
