with the Restrict, with this architecture, an software might be bigger than only one commodity device can cope with because the load is spread throughout multiple devices.
Every single database can run at another compute dimension to help pretty big, "powerful" databases with superior useful resource prerequisites.

Each individual Section of this instance makes an attempt to operate a parameterized insert statement 1,000 times (to make a adequate load to utilize for a examination facts set). When it executes stored strategies, the query processor examines the parameter value that's handed into the procedure in the course of its very first compilation (parameter "sniffing"). The processor caches the resulting strategy and uses it for later on invocations, even if the parameter benefit is different.
after final result set caching is enabled, a dedicated SQL pool can mechanically cache query outcomes for repetitive use.
