Method Detail

awaitGraphIndexUpdate

public static void awaitGraphIndexUpdate(JanusGraph g,
                                         String indexName,
                                         long time,
                                         TemporalUnit unit)

This method blocks and waits until the provided index has been updated across the entire JanusGraph cluster and reached a stable state. This method will wait for the given period of time and throw an exception if the index did not reach a final state within that time. The method simply returns when the index has reached the final state prior to the time period expiring. This is a utility method to be invoked between two JanusGraphManagement.updateIndex(Index, org.janusgraph.core.schema.SchemaAction) calls to ensure that the previous update has successfully persisted.

Parameters:

g -

indexName -

time -

unit -

awaitVertexIndexUpdate

public static void awaitVertexIndexUpdate(JanusGraph g,
                                          String indexName,
                                          String relationTypeName,
                                          long time,
                                          TemporalUnit unit)
