Hi there 🙂

I am trying to figure out whether it’s possible (or not) to run a cluster configuration with operator where there is 1 GRV proxy on each zone, with the intent of minimizing latency on read-only queries.

So far I have tried using `three_data_hall` and configuring `grv_proxies: 1` on the cluster of each zone, with no luck: the GRV proxy and cluster controller always end up in a single zone.

Any tips/ideas? Thanks!

`grv_proxies=N` is a database option that can be configured with `fdbcli`. For your desired case, N=3. Then you need to have 3 stateless pods, one in each zone, running `grv_proxy` class so that these processes are preferred and recruited as GRV proxies.

Thanks for your reply @jzhou! When setting `grv_proxies: 3` on each of the 3 k8s FoundationDB cluster objects, no change happens e.g. the `master`, `commit_proxy`, `cluster_controller`, `grv_proxy` and resolver are all running on the stateless pods of one of the 3 data halls. By `grv_proxy` class you mean that I should somehow have the operator create dedicated pods for this class? Is that supported/possible? I can see for example that one can specify a `coordinatorSelection` but I can’t locate a similar mechanism for `grv_proxy` and other classes which normally run on `stateless` pods; if you have some reference to existing documentation I’ll be happy to read it.

@johscheuer do you know of any way to force the cluster to hire more than 1 GRV proxy role in one of the 3 halls? 🤔

I managed to activate multiple GRV proxies: it was key to not specify a pre-fixed `stateless:` in `processCounts:`.

Thanks everyone!
