I tried to index a table with nested structure. I set the parent entity as
director and put cacheImpl="SortedMapBackedCache" processor=
"SqlEntityProcessor" cachedKey="parent" cacheLookup="director.id" in the
children. However quite a long time has passed but no document was
processed. What was wrong with DIH?
