This is far more of a subjective question and we need to decide if the query is important enough to want to ensure there is never a key lookup to pull those additional columns back from the clustered index. Cache sharing is disabled by default.
If you have multiple SQL Servers using shared storage, that maintenance may hit the storage at the same time. MOFG can have several containers where Checkpoint Files will be stored. The output of native compilation is a DLL.
Added cluster name and availability group name to the backup directory and filename, for databases in availability groups.
For large databases where you access data more or less randomly, you can be sure that you need at least one disk seek to read and a couple of disk seeks to write things.
Even if there are pending updates that are not processed, flushing a bucket causes all indexes to drop their data.
When the first TCP client connection reaches the server from a given IP address, a new cache entry is created to record the client IP, host name, and client lookup validation flag.
Furthermore, when two or more tasks are blocking one other because each task has a lock on a resource in which the other tasks are attempting to place a lock, a deadlock can occur because neither can resolve. This is a commonly exploited performance optimization.
Optimized Tables, and in order to support table changes, Microsoft recommends that at least double the estimated table size is available.
The optimizer handles derived tables, view references, and common table expressions the same way: It avoids unnecessary materialization whenever possible, which enables pushing down conditions from the outer query to derived tables and produces more efficient execution plans.
In this case, histogram statistics are not necessarily useful because index dives can yield better estimates.
Queries that normally could retrieve all the result columns from a secondary index, instead look up the appropriate values from the table data.
Such waste translates into higher resource utilization and latency, pushing your workload beyond what you would consider acceptable performance.
Tree index, the server reads the last row.
