Benjamin Elder (@BenTheElder) you mentioned this might affect test coverage, so if 3 replicas isn't enough I can maybe just make it configurable in the script? |

Yeah -=- I think we were concerned that shards would change behavior (need to be careful not to attempt to query across shards) but probably not replication. We may want to only disable replication in the local testing, and I'm not sure about shard count or more generally what is desirable. I do want to avoid a lot of skew between local and "real" deployments where possible but I'm somewhat skeptical that we need redundant copies in memory for local dev .. cc Grant McCloskey (@MushuEE) Julian Gutierrez Oschmann (@juli4n) |
Fixes #225 - [x] Tests pass - [x] Appropriate changes to documentation are included in the PR Tested local setup: ``` ❯ kubectl exec -n ate-system valkey-cluster-0 -- cat /tmp/valkey.conf | grep cluster-announce cluster-announce-hostname valkey-cluster-0.valkey-cluster-service.ate-system.svc cluster-announce-tls-port 6379 cluster-announce-bus-port 16379 ``` Separate from this, we should decrease the number of clusters, because right now all of these get created: ``` ❯ kubectl exec -n ate-system valkey-cluster-0 -- valkey-cli --tls --cacert /etc/valkey-ca/ca.crt --cert /run/servicedns.podcert.ate.dev/credential-bundle.pem --key /run/servicedns.podcert.ate.dev/credential-bundle.pem cluster nodes d6ca3f519ddcf774bc8df68f7b7ab6c82cc35066 10.244.0.25:6379@16379,valkey-cluster-2.valkey-cluster-service.ate-system.svc master - 0 1781721223000 3 connected 10923-16383 6f66ad32594c1a5dc550729434996eb129112a1f 10.244.0.27:6379@16379,valkey-cluster-3.valkey-cluster-service.ate-system.svc slave d6ca3f519ddcf774bc8df68f7b7ab6c82cc35066 0 1781721224614 3 connected c72d9e9bd165b0f800a135fbda1d8184e8111319 10.244.0.28:6379@16379,valkey-cluster-4.valkey-cluster-service.ate-system.svc slave 1c37cdd7fdcc0a261614a6e3936cc0043fe63d35 0 1781721223594 1 connected 54690be32b6647d43e5e1171e6db92ddf9515ad7 10.244.0.20:6379@16379,valkey-cluster-1.valkey-cluster-service.ate-system.svc master - 0 1781721224614 2 connected 5461-10922 6d862697f8af8750a5280409d1eb2bce9f3f8e0a 10.244.0.26:6379@16379,valkey-cluster-5.valkey-cluster-service.ate-system.svc slave 54690be32b6647d43e5e1171e6db92ddf9515ad7 0 1781721223594 2 connected 1c37cdd7fdcc0a261614a6e3936cc0043fe63d35 10.244.0.22:6379@16379,valkey-cluster-0.valkey-cluster-service.ate-system.svc myself,master - 0 0 1 connected 0-5460 ``` #267 is a quick fix to decrease the pain of setting up the cluster + tearing it down. This would fix the stale IP issue. Signed-off-by: npolshakova <nina.polshakova@solo.io>

Needs a rebase after the other PR, thanks! Raised in the community meeting today for input. |

There will still be crosslot concerns without replicas. But is this making 3 replicas with a single shard or 3 shards with no replicas? We are handling cross-shard queries in things like ListActors but those calls have no consistency promises. I think we could allow for "local" vs "real" deployments as the abstraction layers that need scale and "real" testing should enable that. Can we build an abstraction over the .yaml that allows users to set the replication with a standard default? |
We apply kustomizations to install on kind already, so we can definitely do that. I think we should. But we should also be careful to make sure it doesn't impact the quality of testing. My rough read is that valkey replication won't impact that much but if we did say, only one cluster shard, that might be too unrealistic. |
Fixes #225
(Or at least reduce the cost to spin it up in kind)
