Wait Type PREEMPTIVE_OS_GETCOMPRESSEDFILES

The wait type PREEMPTIVE_OS_GETCOMPRESSEDFILES is ranked #302 by Stedman Solutions and Database Health Monitor.

Wait statistics, in the context of SQL Server, refer to the amount of time that a query spends waiting to access data in the database. When a client application requests data from the database, the request is placed in a queue and the client application must wait for its turn to access the data. The time that the query spends waiting is called a "wait" and is tracked by SQL Server. This information can be used to identify potential performance bottlenecks and optimize the performance of the database. Wait statistics are commonly used by database administrators to diagnose and troubleshoot performance issues in SQL Server.


The PREEMPTIVE_OS_GETCOMPRESSEDFILES wait type in SQL Server is a type of wait that occurs when a task is waiting for the operating system to return information about a compressed file. SQL Server can use compression to reduce the amount of disk space that is used by the database files.

When a task needs to access data in a compressed file, it must first obtain information about the file from the operating system. The PREEMPTIVE_OS_GETCOMPRESSEDFILES wait type indicates that the task is waiting for the operating system to return this information.

This wait type can occur when the operating system is unable to provide the information about the compressed file in a timely manner. This can be due to a variety of factors, such as high workload on the operating system or inadequate resources.

In general, the PREEMPTIVE_OS_GETCOMPRESSEDFILES wait type is not a cause for concern unless it is occurring frequently and causing performance issues. If this is the case, a database administrator can take steps to optimize the access to compressed files, such as increasing the amount of memory available to the SQL Server process or adjusting the compression settings.

In summary, the PREEMPTIVE_OS_GETCOMPRESSEDFILES wait type in SQL Server occurs when a task is waiting for the operating system to return information about a compressed file. This wait type can be a result of high workload or inadequate resources on the operating system. A database administrator can optimize the access to compressed files to reduce the occurrence of this wait type.
