I have a scenario where I need to validate a domain using values in another domain. Rule is : Each value in domain 1 must exist in domain 2. The list of unique values in second domain will be around 50 million. How do I do this in DQS?

You are correct in thinking that the ref integrity scenario is not directly supported in this release of DQS. However, by using a combination of existing techniques, you can get this functionality. I’ll list them below. Also you may want to take a look at some of the short screencasts I’ve done on DQS – here.
To simulate referential integrity:
1) Create a domain from each source field in a KB
2) Create a composite domain from those source fields
3) Create a matching rule for the composite domain in your KB where the value from the first source table is the ‘pivot’ record is set as a prerequisite – more detail here and here.
