I could not find this in the documentation. Neither could I figure this out by trying on a running cluster.
An index is created with defer_build=true. So the index is created but it is not built i.e. only the definition is present but structure/data is not created. My question is: when will the server build it? Will it be built only when somebody manually executes the “build” command? Not until then?
If so, what is the advantage of defer_build=true? Because then its as good as if the index never existed!
