https://issues.apache.org/jira/browse/AMQ-3557 - Performance of consumption with JDBC persistance and Microsoft SQL Server. Fix up default value for maxRows to allign with default page size. Use a large maxPageSize via destination policy for durable subs that have sparse selectors. Same as queues with sparse selectors
