Index state never change to ENABLED on Titan with Amazon DynamoDB backend - amazon-dynamodb

Question

I'm trying to use composite index on DynamoDB and the index never switches from from INSTALLED to REGISTERED state.
Here is the code I used to create it
graph.tx().rollback(); //Never create new indexes while a transaction is active
TitanManagement mgmt=graph.openManagement();
PropertyKey propertyKey=getOrCreateIfNotExist(mgmt, "propertyKeyName");
String indexName = makePropertyKeyIndexName(propertyKey);
if (mgmt.getGraphIndex(indexName)==null) {
mgmt.buildIndex(indexName, Vertex.class).addKey(propertyKey).buildCompositeIndex();
mgmt.commit();
graph.tx().commit();
ManagementSystem.awaitGraphIndexStatus(graph, indexName).status(SchemaStatus.REGISTERED).call();
}else {
mgmt.rollback();
}
A sample of the log is:
...
...
612775 [main] INFO
com.thinkaurelius.titan.graphdb.database.management.GraphIndexStatusWatcher
- Some key(s) on index myIndex do not currently have status REGISTERED: type=INSTALLED 613275 [main] INFO
com.thinkaurelius.titan.graphdb.database.management.GraphIndexStatusWatcher
- Some key(s) on index typeIndex do not currently have status REGISTERED: type=INSTALLED 613275 [main] INFO
com.thinkaurelius.titan.graphdb.database.management.GraphIndexStatusWatcher
- Timed out (PT1M) while waiting for index typeIndex to converge on status REGISTERED

Answer 1

Waiting for a longer time does the trick. Example:
ManagementSystem.awaitGraphIndexStatus(graph, propertyKeyIndexName)
.status(SchemaStatus.ENABLED)
.timeout(10, ChronoUnit.MINUTES) // set timeout to 10 min
.call();
