PowerShell Scripting to Replicate Wasabi Data to MySQL

Write a simple PowerShell script to replicate Wasabi data to a MySQL database.

The CData Cmdlets for Wasabi offer live access to Wasabi 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 Wasabi and the CData Cmdlets for MySQL in PowerShell to replicate Wasabi data to a MySQL database.

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

To authorize Wasabi 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 Wasabi Data

  1. Install the module:

    Install-Module WasabiCmdlets
  2. Connect to Wasabi:

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

    $data = Select-Wasabi -Connection $wasabi -Table "Buckets"

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

    $data = Invoke-Wasabi -Connection $wasabi -Query 'SELECT * FROM Buckets 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 Wasabi 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 Wasabi 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 Wasabi resource (Buckets) and to exist in the database.

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

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

Notes

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

    Select-Wasabi -Connection $wasabi -Table "Buckets" | % { $row = $_ $values = @() $columns | % { $col = $_ $values += $row.$($col) } Add-MySQL -Connection $mysql -Table "Buckets" -Columns $columns -Values $values }
  • If you wish to replicate the Wasabi 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-Wasabi 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')}
