Hi all, I'm wondering, since the datastore is hierarchical, does the number of children an entity has affect the performance on querying on the parents themselves? For example, if I have a set of parents, say...
Jane Margaret Graham Arthur ...and I have a set of children associated with those parents... Jane -Sam -Robert Margaret -Lisa Graham Arthur -Rowen -Jerry ...will the number of children for each parent affect the performance of querying the parents themselves? For instance, if I wanted to select all of the parents (SELECT * FROM parents), that would be easy with the data above. But, since the datastore is hierarchical, does the performance get hampered if say the parents have many thousands or even millions of children? Say, like... Jane -Sam -Robert ...1 million more Margaret ... If so, I'm just wondering if it would make more sense to make the children root entities too, so as not to affect the performance of querying on the parents. Anyways, hope I've explained my question well enough. Thanks in advance! Charles -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
