Hi *, since Tentacle the new default EC plugin is ISA-L, I wanted to ask if anyone is using it in production (maybe for several years already)? I searched tracker for issues with the cauchy technique and found several (haven't read all of them), sometimes in combination with FastEC (which isn't safe to use yet from my understanding), but for example this doesn't mention the technique: https://tracker.ceph.com/issues/74943 and it's not backported to Tentacle yet. So my current impression is that ISA may not be fully production ready, is it? Would it be safer to stick to jerasure for now although it's not being maintained anymore? One specific EC profile I'm dealing with is k=5 m=7 which can be created with "isa + cauchy" or "jerasure + reed_sol_van" but is refused by "isa + reed_sol_van". I'd appreciate any comments! Thanks!
