Hi @<1722061389024989184:profile|ResponsiveKoala38> Thanks for the update. The Microsoft documentation for Azure Managed Redis is not 100% clear - according to None the B0 instance which we use only has one primary shard and we have HA disabled, so this would indicate that only one shard is in use.
OTOH - None states that due to clustered configuration, CROSSSLOT errors may happen and that all multi-key commands must map to the same hash slot.
