Release Notes for Cluster Management API 1.6.3


Cluster Management API (CMAPI) 1.6.3 is a maintenance release of CMAPI. CMAPI is a REST API for administering MariaDB Enterprise ColumnStore in multi-node topologies.

Cluster Management API 1.6.3 was released on 2022-04-20. This release is of General Availability (GA) maturity.

CMAPI 1.6.3 is compatible with MariaDB Enterprise ColumnStore 5.6 and 6. CMAPI 1.6.3 was first released with MariaDB Enterprise ColumnStore 5.6.5 and MariaDB Enterprise ColumnStore 6.2.3.

Notable Changes

  • When a node is added to the cluster using a DNS name, the node's DNS name is added to Columnstore.xml instead of the node's IP address. (MCOL-4804)

    • Prior to this release, when a node's IP address changed after it was added to the cluster, Columnstore.xml still contained the node's old IP address.

    • Starting with this release, CMAPI can adapt to changing IP addresses when the DNS name in Columnstore.xml resolves to the new IP address.

Issues Fixed

  • After the primary server is killed and restarted, MaxScale and CMAPI could each choose different primary servers. (MCOL-5052)
