PowerShell

Ferramentas para PowerShell

Exemplo 1: grava um registro contendo a string fornecida ao parâmetro -Text.

Write-KINRecord -Text "test data from string" -StreamName "mystream" -PartitionKey "Key1"

Exemplo 2: grava um registro contendo os dados contidos no arquivo especificado. O arquivo é tratado como uma sequência de bytes, portanto, se ele contiver texto, ele deverá ser gravado com qualquer codificação necessária antes de ser usado com esse cmdlet.

Write-KINRecord -FilePath "C:\TestData.txt" -StreamName "mystream" -PartitionKey "Key2"
