Wei-Chiu Chuang updated HDDS-15071:
-----------------------------------
Release Note: New optional SCM configuration
hdds.scm.replication.reconstruction.global.limit (default 0, disabled) caps
cluster-wide in-flight EC reconstruction; when the limit is reached, additional
reconstruction is deferred until slots free up, while decommission 1-1
replication continues. Default behavior is unchanged.
