Cassandra ADO.NET Provider

Standard ADO.NET Access to Cassandra

The Cassandra ADO.NET Provider offers the most natural way to access Cassandra data from any .NET application. Simply use Cassandra Data Provider objects to connect and access data just as you would access any traditional database. You will be able to use the Cassandra Data Provider through Visual Studio Server Explorer, in code through familiar classes, and in data controls like DataGridView, GridView, DataSet, etc.

The CData ADO.NET Provider for Apache Cassandra hides the complexity of accessing data and provides additional powerful security features, smart caching, batching, socket management, and more.

Working with DataAdapters, DataSets, DataTables, etc.

The Cassandra Data Provider has the same ADO.NET architecture as the native .NET data providers for SQL Server and OLEDB, including: CassandraConnection, CassandraCommand, CassandraDataAdapter, CassandraDataReader, CassandraDataSource, CassandraParameter, etc. Because of this you can now access Cassandra data in an easy, familiar way.

For example:

using (CassandraConnection conn = new CassandraConnection("...")) {
	string select = "SELECT * FROM CQL Queries";
	CassandraCommand cmd = new CassandraCommand(select, conn);
	CassandraDataAdapter adapter = new CassandraDataAdapter(cmd);
	using (adapter) {
		DataTable table = new DataTable();
		adapter.Fill(table);		
		...
	}
}

More Than Read-Only: Full Update/CRUD Support

Cassandra Data Provider goes beyond read-only functionality to deliver full support for Create, Read, Update, and Delete operations (CRUD). Your end-users can interact with the data presented by the Cassandra Data Provider as easily as interacting with a database table.

using (CassandraConnection connection = new CassandraConnection(connectionString)) {
	CassandraDataAdapter dataAdapter = new CassandraDataAdapter(
	"SELECT Id, Where FROM CQL Queries", connection);
  
	dataAdapter.UpdateCommand = new CassandraCommand(
		"UPDATE CQL Queries SET Where = @Where " +
		"WHERE Id = @ID", connection);

	dataAdapter.UpdateCommand.Parameters.AddWithValue("@Where", "Where");
	dataAdapter.UpdateCommand.Parameters.AddWithValue("@Id", "80000173-1387137645");

	DataTable CQL QueriesTable = new DataTable();
	dataAdapter.Fill(CQL QueriesTable);

	DataRow firstrow = CQL QueriesTable.Rows[0];
	firstrow["Where"] = "New Location";

	dataAdapter.Update(CQL QueriesTable);
}
