Examples with ConfigurationManagementGraph org.janusgraph.graphdb.management.ConfigurationManagementGraph used on opensource projects

Example 11 with ConfigurationManagementGraph

use of org.janusgraph.graphdb.management.ConfigurationManagementGraph in project janusgraph by JanusGraph.

the class ConfiguredGraphFactory method updateTemplateConfiguration.

/**
 * Update template configuration by updating supplied existing properties and adding new ones to the
 * {@link Configuration}; your updated Configuration may not contain the property "graph.graphname";
 * NOTE: Any graph using a configuration that was created using the template configuration must--
 * 1) be closed and reopened on every JanusGraph Node 2) have its corresponding Configuration removed
 * and 3) recreate the graph-- before the update is guaranteed to take effect.

Example 12 with ConfigurationManagementGraph

use of org.janusgraph.graphdb.management.ConfigurationManagementGraph in project janusgraph by JanusGraph.
