Connect to Kafka Data from PowerBuilder
This article demonstrates how to access Kafka data from Appeon PowerBuilder using the CData ADO.NET Provider for Kafka.
This article demonstrates using the CData ADO.NET Provider for Kafka in PowerBuilder, showcasing the ease of use and compatibility of these standards-based controls across various platforms and development technologies that support Microsoft .NET, including Appeon PowerBuilder.
This article shows how to create a basic PowerBuilder application that uses the CData ADO.NET Provider for Kafka to perform reads and writes.
- In a new WPF Window Application solution, add all the Visual Controls needed for the connection properties. Below is a typical connection string:
User=admin;Password=pass;BootStrapServers=https://localhost:9091;Topic=MyTopic;
Set BootstrapServers and the Topic properties to specify the address of your Apache Kafka server, as well as the topic you would like to interact with.
Authorization Mechanisms
- SASL Plain: The User and Password properties should be specified. AuthScheme should be set to 'Plain'.
- SASL SSL: The User and Password properties should be specified. AuthScheme should be set to 'Scram'. UseSSL should be set to true.
- SSL: The SSLCert and SSLCertPassword properties should be specified. UseSSL should be set to true.
- Kerberos: The User and Password properties should be specified. AuthScheme should be set to 'Kerberos'.
You may be required to trust the server certificate. In such cases, specify the TrustStorePath and the TrustStorePassword if necessary.
- Add the DataGrid control from the .NET controls.
-
Configure the columns of the DataGrid control. Below are several columns from the Account table:
<DataGrid AutoGenerateColumns="False" Margin="13,249,12,14" Name="datagrid1" TabIndex="70" ItemsSource="{Binding}"> <DataGrid.Columns> <DataGridTextColumn x:Name="idColumn" Binding="{Binding Path=Id}" Header="Id" Width="SizeToHeader" /> <DataGridTextColumn x:Name="nameColumn" Binding="{Binding Path=Id}" Header="Id" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid> - Add a reference to the CData ADO.NET Provider for Kafka assembly.
Connect the DataGrid
Once the visual elements have been configured, you can use standard ADO.NET objects like Connection, Command, and DataAdapter to populate a DataTable with the results of an SQL query:
System.Data.CData.ApacheKafka.ApacheKafkaConnection conn
conn = create System.Data.CData.ApacheKafka.ApacheKafkaConnection(connectionString)
System.Data.CData.ApacheKafka.ApacheKafkaCommand comm
comm = create System.Data.CData.ApacheKafka.ApacheKafkaCommand(command, conn)
System.Data.DataTable table
table = create System.Data.DataTable
System.Data.CData.ApacheKafka.ApacheKafkaDataAdapter dataAdapter
dataAdapter = create System.Data.CData.ApacheKafka.ApacheKafkaDataAdapter(comm)
dataAdapter.Fill(table)
datagrid1.ItemsSource=table.DefaultView
The code above can be used to bind data from the specified query to the DataGrid.
