thank you very much for your helpful answers, in fact I'm doing a research on all Nosql technologies and Cloud data management systems in order to develop a system for my particular highly heterogeneous data. That's why I need to know what each of them can offer and what are the potential limitations. I saw some people using Datastore but they have a replica for there data on a RDBMS only to process ad-hoc queries. So thank you vry much for the BigQuery link I didn't hear about it before.
As it's an interesting discussion (I hope for you too), do you think that the other NoSql (hbase, Hive, cassandra ) have the same problem of ad-hoc queries and so can we use BigQuery with those databases or it's designed for google projects?
