Description

The value of the configuration parameter can be changed during cluster initialization (IgniteImpl#init). System components do not see the actual configuration values at startup (since locally this values is applied later).
This can cause confusion when a component reads a default configuration value at startup, which then changes when the distributed configuration is applied on the local node.
