Summary

The rule collects the Windows "Dusty corner scan retries/sec (user-issued)" performance counter for internal XTP engine cursors.

The XTP Cursors performance object contains counters related to internal XTP engine cursors. Cursors are the low-level building blocks the XTP engine uses to process Transact-SQL queries. As such, you do not typically have direct control over them.

Dusty corner scan retries/sec (user-issued) - The number of scan retries due to write conflicts during dusty corner sweeps issued by a user's full-table scan (on average), per second. This is a very low-level counter, not intended for customer use.

Note that this rule is enabled only for SQL editions supporting Memory-Optimized Data (64-bit Enterprise, Developer, or Evaluation edition).
