> We set a few memory usage related parameter such as sort-memory, group-memory and join-memory in asterix-configuration.xml. There are a few more parameters as well. An issue is that each parameter is used individually by Asterix codebase and there is no global management regarding these parameters. 
> Thus, for example, we can't guard a situation where memory allocation of sub components such as sort-memory and group-memory is greater than the NC java heap size.
> It would be really nice if we have a query memory budgeting feature, too. If it is evident that a query will exceed certain memory budget, we can warn users rather than issuing runtime Out Of Memory error.
