-Starting Dgraph version `20.3.0`, indexes are computed in the background.
-This requires that you wait for indexing to complete before running queries.
-You could do that using following code.
-
-```java
-AlterUtils.waitForIndexing(dgraphClient, "name", Collections.singletonList("exact"), false, false);
-```
-
 `Operation` contains other fields as well, including drop predicate and
 drop all. Drop all is useful if you wish to discard all the data, and start from
 a clean slate, without bringing the instance down.
