Ramesh Reddy commented on TEIID-3166:
-------------------------------------

I can't think why always being on is bad thing, it can definitely simplify the logic. I can add a translator property and keep it by default ON. However, I need to upgrade the java driver for this to 2.12.

> When querying a MongoDB, steps of computation are limited to 100MiB. Querying large databases can easily exceed this limit, so usually allowDiskUse:true is passed in the aggregate query:

> In Teiid, however, there is currently no way to specify this with SQL.
