SQL Server XTP Cursors object
Applies to: 
SQL Server
The SQL Server XTP Cursors performance object contains counters related to internal In-Memory OLTP engine cursors. Cursors are the low-level building blocks the In-Memory OLTP engine uses to process Transact-SQL queries. As such, you do not typically have direct control over them.
This table describes the SQL Server XTP Cursors counters.
| Counter | Description |
|---|---|
| Cursor deletes/sec | The number of cursor deletes (on average), per second. |
| Cursor inserts/sec | The number of cursor inserts (on average), per second. |
| Cursor scans started /sec | The number of cursor scans started (on average), per second. |
| Cursor unique violations/sec | The number of unique-constraint violations (on average), per second. |
| Cursor updates/sec | The number of cursor updates (on average), per second. |
| Cursor write conflicts/sec | The number of write-write conflicts to the same row version (on average), per second. |
| 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. |
| Expired rows removed/sec | The number of expired rows removed by cursors (on average), per second. |
| Expired rows touched/sec | The number of expired rows touched by cursors (on average), per second. |
| Rows returned/sec | The number of rows returned by cursors (on average), per second. |
| Rows touched/sec | The number of rows touched by cursors (on average), per second. |
| Tentatively-deleted rows touched/sec | The number of expiring rows touched by cursors (on average), per second. A row is expiring if the transaction that deleted it is still active (i.e. has not yet committed or aborted.) |
Example
You begin to explore the query performance counters in this object using this T-SQL query on the sys.dm_os_performance_counters dynamic management view:
