Starting with MarkLogic 12.0.0, the MarkLogic CloudFormation Template only supports Amazon Linux 2023. The OSType parameter, introduced in MarkLogic 11.3.1 (combined), is no longer supported in the MarkLogic 12.0.0 Cloud Formation Template.
The MarkLogic 12.0.0 Cloud Formation Template also includes enhancements to the Node Manager Lambda function to better handle attachment of the secondary network interface hosts in the cluster.
The supported instance types have been updated:
- GPU instance types have been removed
- Support for additional instance families (m7i, m7i-flex, m7a, c7i, c7i-flex, c7a, r7i, r7iz, r7a, i7ie)
