Some aspects of Context Store configuration can be changed dynamically, but not all. See lists below for details.
Changes requiring cluster restart
Data-grid sizing is not dynamic (ContextStoreManager "Startup Configuration" attributes); you must shut down all the nodes and start the nodes simultaneously if you make changes to the data-grid.
The Context Store cluster does not support scaling out dynamically. After adding or removing a node to the cluster, you must shut down all the nodes and start the nodes simultaneously.
Changes requiring service reinstall
ContextStoreQuery - reinstall this service after attributes changes.
Changes requiring that the feature is toggled off and on again
ContextStoreManager "External Data Mart Configuration" attributes - enable/disable the EDM feature(s) to make configuration changes.
ContextStoreManager "Geo Redundancy Configuration" attributes - enable/disable the GEO feature to make configuration changes.
ContextStoreNotify - to make changes to the configuration of a subscription, you must first disable the subscription, make the changes, and then enable the subscription again.
Changes that do not require any action other than the change in attribute value itself
ContextStoreManager "Run-time Service Configuration"
ContextStoreManager "Streams Configuration"
ContextStoreRest "External Data Mart Configuration"
