Has anybody tried to replicate Oxigraph? RocksDB has replication helpers, but of course an independent replication layer is also an option. I am now implementing my own naive replication layer by proxying interactions with Oxigraph through an Actix actor, which takes care of sending the updates to other nodes in the cluster, but probably someone has done a better job at implementing something similar. |

Hey! The only kind of replication Oxigraph supported was the RocksDB secondary mode. I removed support because we were encountering significant bugs with it and it only supported local replication. Sending updates to all nodes sounds like a fairly good approach, one just need to make sure they are always applied in the same order (and be fine to have different blank node identifiers in the different instances). |

Thank you for your quick answer.
Yes, probably using something like vector clocks is enough? But that's a design question on my side, closing this. |
