Towards multiverse databases Marzoev et al., The central idea behind multiverse databases is to push the data access and privacy rules into the database itself. With multiverse databases, each user sees a consistent “parallel universe” database containing only the data that user is allowed to see.

Partitioning is the concept of splitting large tables logically into smaller pieces for better performance of the database. However, a rule of thumb is that the size of the table should exceed the physical memory of the database server. The exact point at which a table will benefit from partitioning depends on the application.

It’s less of an apples-to-oranges comparison and more like apples-to-orange-sherbet. Even a service that doesn’t turn around and call another service usually has to do something like talk to a database, which is another form of RPC. But the answer isn’t that simple. Let’s take a look at the bigger picture. ?? Messaging doesn’t do that.

For example, consider a database system that is distributed across a data center, or even across data centers. On the other hand, one can implement this system with encryption/decryption units between the compute and the storage. Second, as the trust boundary grows, the classes of adversary that can permeate that boundary increases.

NoSQL databases are often compared by various non-functional criteria, such as scalability, performance, and consistency. At the same time, NoSQL data modeling is not so well studied and lacks the systematic theory found in relational databases. Document databases advance the BigTable model offering two significant improvements.

Fellow SQL Server MVP Paul White theorizes that it could be related to using information from the outer input’s leaf to hint the storage engine to avoid duplicated effort by the read-ahead mechanisms. They’re also quite efficient, using a Left Semi Join optimization with a short-circuit. You can find the details here. So far, so good.
