Cross-AZ in Managed Service

Multi-AZ or Cross-AZ configurations are supported in some Managed Service editions.

The SingleStore architecture expects low, consistent latency between nodes – i.e. it expects them to be on the same local area network. Cross-AZ latencies can sometimes be high (over 100 msec), leading to dropped heart beat messages or other failures in SingleStore DB. SingleStore Managed Service has special handling and monitoring to counter the latency and increased data transfer costs.
