Redis Icon Redis Cmdlets

An easy-to-use set of PowerShell Cmdlets offering real-time access to Redis high-performance data stores. The Cmdlets allow users to easily read, write, update, and delete live data - just like working with SQL server.

Pipe Redis Data to CSV in PowerShell

Use standard PowerShell cmdlets to access Redis tables.

The CData Cmdlets Module for Redis is a standard PowerShell module offering straightforward integration with Redis. Below, you will find examples of using our Redis Cmdlets with native PowerShell cmdlets.

Creating a Connection to Your Redis Data

Set the following connection properties to connect to a Redis instance:

  • Server: Set this to the name or address of the server your Redis instance is running on. You can specify the port in Port.
  • Password: Set this to the password used to authenticate with a password-protected Redis instance , using the Redis AUTH command.

Set UseSSL to negotiate SSL/TLS encryption when you connect.

$conn = Connect-Redis  -Server "$Server" -Port "$Port" -Password "$Password"

Selecting Data

Follow the steps below to retrieve data from the Customers table and pipe the result into to a CSV file:

Select-Redis -Connection $conn -Table Customers | Select -Property * -ExcludeProperty Connection,Table,Columns | Export-Csv -Path c:\myCustomersData.csv -NoTypeInformation

You will notice that we piped the results from Select-Redis into a Select-Object cmdlet and excluded some properties before piping them into an Export-Csv cmdlet. We do this because the CData Cmdlets append Connection, Table, and Columns information onto each "row" in the result set, and we do not necessarily want that information in our CSV file.

The Connection, Table, and Columns are appended to the results in order to facilitate piping results from one of the CData Cmdlets directly into another one.

Deleting Data

The following line deletes any records that match the criteria:

Select-Redis -Connection $conn -Table Customers -Where "Country = US" | Remove-Redis

Inserting and Updating Data

The cmdlets make data transformation easy as well as data cleansing. The following example loads data from a CSV file into Redis, checking first whether a record already exists and needs to be updated instead of inserted.

Import-Csv -Path C:\MyCustomersUpdates.csv | %{
  $record = Select-Redis -Connection $Redis -Table Customers -Where ("Id = `'"+$_.Id+"`'")
    Update-Redis -Connection $redis -Table Customers -Columns ("City","CompanyName") -Values ($_.City, $_.CompanyName) -Where ("Id = `'"+$_.Id+"`'")
    Add-Redis -Connection $redis -Table Customers -Columns ("City","CompanyName") -Values ($_.City, $_.CompanyName)

As always, our goal is to simplify the way you connect to data. With cmdlets users can install a data module, set the connection properties, and start building. Download Cmdlets and start working with your data in PowerShell today!
