Function Set-DbaQueryStoreConfig { <# .SYNOPSIS Configure Query Store settings for a specific or multiple databases. .DESCRIPTION Configure Query Store settings for a specific or multiple databases. .PARAMETER SqlInstance The SQL Server that you're connecting to. .PARAMETER SqlCredential SqlCredential object used to connect to the SQL Server as a different user. .PARAMETER Databases Set Query Store configuration for specific databases. .PARAMETER Exclude Set Query Store configuration for all databases on the connected server except databases entered through this parameter. .PARAMETER AllDatabases Run command against all user databases .PARAMETER State Set the state of the Query Store. Valid options are "ReadWrite", "ReadOnly" and "Off". .PARAMETER FlushInterval Set the flush to disk interval of the Query Store in seconds. .PARAMETER CollectionInterval Set the runtime statistics collection interval of the Query Store in minutes. .PARAMETER MaxSize Set the maximum size of the Query Store in MB. .PARAMETER CaptureMode Set the query capture mode of the Query Store. Valid options are "Auto" and "All". .PARAMETER CleanupMode Set the query cleanup mode policy. Valid options are "Auto" and "Off". .PARAMETER StaleQueryThreshold Set the stale query threshold in days. .PARAMETER WhatIf Shows what would happen if the command were to run .PARAMETER Confirm Prompts for confirmation of every step. For example: Are you sure you want to perform this action? Performing the operation "Changing Desired State" on target "pubs on SQL2016\VNEXT". [Y] Yes [A] Yes to All [N] No [L] No to All [S] Suspend [?] Help (default is "Y"): .NOTES Author: Enrico van de Laar ( @evdlaar ) Tags: QueryStore dbatools PowerShell module (https://dbatools.io) Copyright (C) 2016 Chrissy LeMaire This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
