Amazon S3 Cmdlets

An easy-to-use set of PowerShell Cmdlets offering real-time access to Amazon S3 data. The Cmdlets allow users to easily access live data - just like working with SQL server.

Write a simple PowerShell script to replicate Amazon S3 data to a MySQL database.

The CData Cmdlets for Amazon S3 offer live access to Amazon S3 data from within PowerShell. Using PowerShell scripts, you can easily automate regular tasks like data replication. This article will walk through using the CData Cmdlets for Amazon S3 and the CData Cmdlets for MySQL in PowerShell to replicate Amazon S3 data to a MySQL database.

After obtaining the needed connection properties, accessing Amazon S3 data in PowerShell and preparing for replication consists of four basic steps.

To authorize Amazon S3 requests, provide the credentials for an administrator account or for an IAM user with custom permissions. Set AccessKey to the access key Id. Set SecretKey to the secret access key.

Note: You can connect as the AWS account administrator, but it is recommended to use IAM user credentials to access AWS services.

For information on obtaining the credentials and other authentication methods, refer to the Getting Started section of the Help documentation.

Collecting Amazon S3 Data

  1. Install the module:

    Install-Module AmazonS3Cmdlets
  2. Connect to Amazon S3:

    $amazons3 = Connect-AmazonS3 -AccessKey $AccessKey -SecretKey $SecretKey
  3. Retrieve the data from a specific resource:

    $data = Select-AmazonS3 -Connection $amazons3 -Table "ObjectsACL"

    You can also use the Invoke-AmazonS3 cmdlet to execute pure SQL-92 statements:

    $data = Invoke-AmazonS3 -Connection $amazons3 -Query 'SELECT * FROM ObjectsACL WHERE Name = @Name' -Params @{'@Name'='TestBucket'}
  4. Save a list of the column names from the returned data.

    $columns = ($data | Get-Member -MemberType NoteProperty | Select-Object -Property Name).Name

Inserting Amazon S3 Data into the MySQL Database

With the data and column names collected, you are ready to replicate the data into a MySQL database.

  1. Install the module:

    Install-Module MySQLCmdlets
  2. Connect to MySQL, using the server address and port of the MySQL server, valid user credentials, and a specific database with the table in which the data will be replicated:

    $mysql = Connect-MySQL -User $User -Password $Password -Database $Database -Server $Server -Port $Port
  3. Loop through the Amazon S3 data, store the values, and use the Add-MySQL cmdlet to insert the data into the MySQL database, one row at a time. In this example, the table will need to have the same name as the Amazon S3 resource (ObjectsACL) and to exist in the database.

    $data | % { $row = $_ $values = @() $columns | % { $col = $_ $values += $row.$($col) } Add-MySQL -Connection $mysql -Table "ObjectsACL" -Columns $columns -Values $values }

You have now replicated your Amazon S3 data to a MySQL database. This gives you freedom to work with Amazon S3 data in the same way that you work with other MySQL tables, whether that is performing analytics, building reports, or other business functions.


  • Once you have connected to Amazon S3 and MySQL in PowerShell, you can pipe command results to perform the replication in a single line:

    Select-AmazonS3 -Connection $amazons3 -Table "ObjectsACL" | % { $row = $_ $values = @() $columns | % { $col = $_ $values += $row.$($col) } Add-MySQL -Connection $mysql -Table "ObjectsACL" -Columns $columns -Values $values }
  • If you wish to replicate the Amazon S3 data to another database using another PowerShell module, you will want to exclude the Columns, Connection, and Table columns from the data returned by the Select-AmazonS3 cmdlet since those columns are used to help pipe data from one CData cmdlet to another:

    $columns = ($data | Get-Member -MemberType NoteProperty | Select-Object -Property Name).Name | ? {$_ -NotIn @('Columns','Connection','Table')}
