What is the SLA?

See Service Availability (SLA) for complete details. SLA is not provided for Single Node Transactions services, as High Availability (HA) features are not enabled in single-node configurations.

If an SLA is needed, please consider the Replicated Transactions topology.

What is configurable?

At time of service launch, region, instance sizes and storage sizes, and MariaDB Enterprise Server version are configurable.

After launch, MariaDB Enterprise Server is configurable using SkySQL's Configuration Manager. A full list of configurable parameters is available.
