Class AsyncLaneSwitcher

  • public class AsyncLaneSwitcher
extends java.lang.Object
    Coordinates the switching of indexing lane for indexes which are to be imported. Its support idempotent operation i.e. if an indexer is switched to temp lane then a repeat of same operation would be no op.

      All Methods Static Methods Concrete Methods 
      Modifier and Type Method Description
      static java.lang.String getTempLaneName​(java.lang.String laneName)  
      static boolean isLaneSwitched​(NodeBuilder idxBuilder)  
      static boolean isNone​(PropertyState previousAsync)  
      static void revertSwitch​(NodeBuilder idxBuilder, java.lang.String indexPath)  
      static void switchLane​(NodeBuilder idxBuilder, java.lang.String laneName)
      Make a copy of current async value and replace it with one required for offline reindexing The switch lane operation can be safely repeated and if the index lane is found to be switched already it would not be modified
