public void flushKeyValueStores()
throws ManagementException;
public void flushKeyValueStores(int[] nodeIDs)
throws ManagementException;
Request that all application state waiting for persistence in all key/value stores in all event router nodes in the cluster be persisted to the backing database as soon as possible. Any unwritten application state buffered in the key/value stores at the time this operation is invoked will be flushed. Any further application state committed after the flush operation is initiated will be persisted at some future time in accordance with normal key/value store behaviour. This method blocks until the flush operation has completed. This operation requests that all application state waiting for persistence in all key/value stores in all event router nodes in the cluster be persisted to the backing database as soon as possible. |
