Guys, I want to introduce another breaking change for 2.0.
Currently SQL is being processed differently when we call method `query` on partitioned cache and on replicated: on replicated cache we do not do any extra processing and execute the query as is on current node. This behavior historically existed for performance reasons. But it is not obvious and leads to wrong query results. This issue becomes even more creepy with JDBC and ODBC drivers. In 2.0 I want to execute all the SQL queries the same way through the whole processing pipeline to guaranty the correct result irrespectively to the cache that was the query originator. To be able to have the old behavior (skip all the preprocessing and run query on current node) add a flag isReplicatedOnly() on SqlQuery and SqlFieldsQuery. It will be disabled by default and if one knows that the only replicated tables participate in a query, then he can enable it for better performance. Sergi
