Scale-In with MariaDB Xpand


MariaDB Xpand can be scaled in, which reduces the number of Xpand nodes in the cluster.

Use Cases

Some use cases for scale-in:

  • To reduce operating costs following a peak event (i.e., following Cyber-Monday).

  • To allocate servers for other purposes.

  • To remove failing hardware. (See ALTER CLUSTER DROP to drop a permanently failed node.)
