Member Data Documentation

uint ExecStreamResourceQuantity::nThreads

Number of dedicated threads the stream may request while executing.

Non-parallelized streams have 0 for this setting, meaning the only threads which execute them are managed by the scheduler instead.

uint ExecStreamResourceQuantity::nCachePages

Number of cache pages the stream may pin while executing.

This includes both scratch pages and I/O pages used for storage access.
