Release Notes for Cluster Management API 22.08.1

Cluster Management API (CMAPI) 22.08.1 is a maintenance release of CMAPI. CMAPI is a REST API for administering MariaDB Enterprise ColumnStore in multi-node topologies.

Cluster Management API 22.08.1 was released on 2022-09-12. This release is of General Availability (GA) maturity.

CMAPI 22.08.1 is compatible with MariaDB Enterprise ColumnStore 22.08. CMAPI 22.08.1 was first released with MariaDB Enterprise ColumnStore 22.08.1.

Notable Changes

• CMAPI configures ColumnStore to allow read queries to be executed on any node. (MCOL-4770)
  • In previous releases, CMAPI only added an ExeMgr section for the primary node to Columnstore.xml.
  • Starting with this release, CMAPI adds an ExeMgr section for every node to Columnstore.xml, which means that any node can execute read queries.

• Since Enterprise ColumnStore 22.08 merges the ExeMgr process into the PrimProc process, CMAPI no longer tries to start ExeMgr on a node when the binary is not present. (MCOL-5138)

• Some redundant log messages have been removed from the CMAPI log. (MCOL-5157)
