Hi folks, if we have multiple instances of quadrant, one marked as a leader, and the other should be a flower, how does the quadrant handle write from flowers? What happens if data should be written in shards that are not in the local flower data? |

Leader election happens automatically. Any node can be the leader. The elected leader might change if a node goes down. Data is spread across nodes in (replicated) shards. If a shard doesn't have a local replica, any other node having a replica is contacted and used. Please read through our distributed deployment documentation here, it elaborates on all of this in detail: https://qdrant.tech/documentation/guides/distributed_deployment/ By default, all nodes accept reads and writes and updates are not serialized through the leader. If you'd like to have strong consistency guarantees you can configure it as described here: https://qdrant.tech/documentation/guides/distributed_deployment/#consistency-guarantees |
