This table uses columnstore for its primary storage to produce batch mode execution later on. Batch mode execution is all about speed. You might call this arrangement "off-row" or "out-of-batch" storage. The flag indicates in-batch data storage when the LSB is clear (set to zero). DROP TABLE IF EXISTS #T ; GO.

Our demo project on a not-so-hot-anymore framework that we want to migrate. All in all, Frankenstein Migration — is an attempt to combine “good” and “fast” migration types in which we get high-quality results such as the complete re-write that is combined with the delivery speed of gradual migration.

Both Xen and KVM have had many performance and security improvements, and workloads can now be tuned to run at almost bare metal speeds (say, a 3% loss or less). Appliance manufacturers hire kernel engineers to develop custom features, including storage appliances. Outside of EC2, many other providers are deploying on KVM.
