PowerShell 7.3 - implementing Filtering and Sorting Large CSV Data Efficiently
After trying multiple solutions online, I still can't figure this out. I'm building a feature where I've searched everywhere and can't find a clear answer. I'm trying to process a large CSV file containing over 100,000 records using PowerShell 7.3, and I'm working with important performance optimization when filtering and sorting the data. My objective is to filter the records based on a specific condition and sort them by another column. Here's the code snippet I am currently using: ```powershell $csvData = Import-Csv -Path 'C:\data\largefile.csv' $filteredData = $csvData | Where-Object { $_.Status -eq 'Active' } $sortedData = $filteredData | Sort-Object -Property CreatedDate -Descending $sortedData | Export-Csv -Path 'C:\data\filtered_sorted.csv' -NoTypeInformation ``` When I run this code, it takes a very long time to execute, and I often get a "The operation has timed out" behavior after a few minutes. I've tried using `Select-Object` to limit the number of columns being processed, but it doesn't seem to help. Additionally, the machine has ample resources but still struggles with this operation. I've read that using `Measure-Command` could help identify bottlenecks, but Iām unsure how to apply this in my case effectively. Could there be a more efficient way to handle filtering and sorting for large datasets in PowerShell? Any suggestions or alternative methods would be greatly appreciated. What am I doing wrong? For context: I'm using Powershell on Linux. Cheers for any assistance! The project is a CLI tool built with Powershell.
