Avro Data Cmdlets

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



Use standard PowerShell cmdlets to access Avro tables.

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

Creating a Connection to Your Avro Data

Connect to your local Avro file(s) by setting the URI connection property to the location of the Avro file.

$conn = Connect-Avro  -URI "$URI"

Selecting Data

Follow the steps below to retrieve data from the SampleTable_1 table and pipe the result into to a CSV file:

Select-Avro -Connection $conn -Table SampleTable_1 | Select -Property * -ExcludeProperty Connection,Table,Columns | Export-Csv -Path c:\mySampleTable_1Data.csv -NoTypeInformation

You will notice that we piped the results from Select-Avro 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.
