Transparent compression would also be a useful feature here. On a lot of workloads it would result in the replication cost being more like 1.5x than the 3x you’d typically deploy FDB with, especially if you ran zstd training in the background and made a custom dictionary instead of just using LZ4.
- spullara 8y agoYou could also just use a filesystem that does compression on top of it. Might be better? Another thing to watch out for is that if you format it ext4 don't make enormous as it will write lots and lots of superblocks. Found out the hard way.
- nmelkozerov 8y agoIt's definitely a cool idea. I think it makes sense to make it configurable, since some workloads might write already compresses bytes and then it's not possible to compress them any further.
