Target Service, API
The driver provides native connectivity to Amazon Redshift data warehouse based on PostgreSQL 8.0.2. Connects directly to Redshift clusters across all AWS regions using the Redshift SQL interface.
Schema, Data Model
Models Redshift as a traditional relational database with full access to schemas, tables, views, and stored procedures. Dynamically discovers metadata including table definitions, columns, data types, and relationships.
Key Objects
Databases, Schemas, Tables, Views, Stored Procedures, User-Defined Functions, and system tables. Full access to all Redshift database objects including external tables and Spectrum data.
Operations
Full ANSI SQL-92 support with PostgreSQL compatibility. Supports all DML operations (SELECT, INSERT, UPDATE, DELETE), complex JOINs, window functions, CTEs, and Redshift-specific features. Query optimization pushes operations to Redshift for server-side processing.
Authentication
Standard database authentication with Username/Password. Connects using Server hostname/IP, Port, Database name, and credentials. Supports SSL/TLS encryption for secure connections. Compatible with IAM authentication when configured.

Standard ADO.NET Access to Redshift
The Amazon Redshift ADO.NET Provider offers the most natural way to access Redshift data from any .NET application. Simply use Amazon Redshift Data Provider objects to connect and access data just as you would access any traditional database. You will be able to use the Amazon Redshift 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 Amazon Redshift 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 Amazon Redshift Data Provider has the same ADO.NET architecture as the native .NET data providers for SQL Server and OLEDB, including: RedshiftConnection, RedshiftCommand, RedshiftDataAdapter, RedshiftDataReader, RedshiftDataSource, RedshiftParameter, etc. Because of this you can now access Redshift data in an easy, familiar way.
For example:
using (RedshiftConnection conn = new RedshiftConnection("...")) {
string select = "SELECT * FROM RedshiftTable";
RedshiftCommand cmd = new RedshiftCommand(select, conn);
RedshiftDataAdapter adapter = new RedshiftDataAdapter(cmd);
using (adapter) {
DataTable table = new DataTable();
adapter.Fill(table);
...
}
}
More Than Read-Only: Full Update/CRUD Support
Amazon Redshift 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 Amazon Redshift Data Provider as easily as interacting with a database table.
using (RedshiftConnection connection = new RedshiftConnection(connectionString)) {
RedshiftDataAdapter dataAdapter = new RedshiftDataAdapter(
"SELECT Id, Where FROM RedshiftTable", connection);
dataAdapter.UpdateCommand = new RedshiftCommand(
"UPDATE RedshiftTable SET Where = @Where " +
"WHERE Id = @ID", connection);
dataAdapter.UpdateCommand.Parameters.AddWithValue("@Where", "Where");
dataAdapter.UpdateCommand.Parameters.AddWithValue("@Id", "80000173-1387137645");
DataTable RedshiftTableTable = new DataTable();
dataAdapter.Fill(RedshiftTableTable);
DataRow firstrow = RedshiftTableTable.Rows[0];
firstrow["Where"] = "New Location";
dataAdapter.Update(RedshiftTableTable);
}
ADO.NET Provider Performance
With traditional approaches to remote access, performance bottlenecks can spell disaster for applications. Regardless if an application is created for internal use, a commercial project, web, or mobile application, slow performance can rapidly lead to project failure. Accessing data from any remote source has the potential to create these problems. Common issues include:
- Network Connections - Slow network connections and latency issues are common in mobile applications.
- Service Delays - Delays due to service interruptions, resulting in server hardware or software updates.
- Large Data - Intentional or unintentional requests for large amounts of data.
- Disconnects - Complete loss of network connectivity.
The CData ADO.NET Provider for Amazon Redshift solves many of these issues with support for replication queries that can be used to sync data to local databases, greatly improving the performance and dramatically reduce application bottlenecks.
More information about ADO.NET Provider performance capabilities are available in the included documentation.
Visual Studio Integration & Server Explorer
Working with the new Amazon Redshift ADO.NET Provider is easy. As a fully-managed .NET Data Provider, the Amazon Redshift Data Provider integrates seamlessly with the Visual Studio development environment as well as any .NET application.
As an ADO.NET Data Provider, Amazon Redshift ADO.NET Provider can be used to access and explore Amazon Redshift data directly from the Visual Studio Server Explorer.
It's easy. As a standard ADO.NET adapter, developers can connect the Server Explorer to Amazon Redshift ADO.NET Provider just like connecting to any standard database.
- Add a new Data Connection from the Server Explorer and select the Amazon Redshift Data Source
- Configure the basic connection properties to access your Amazon Redshift account data.
Explore all of the data available! Amazon Redshift ADO.NET Provider makes it easy to access live Amazon Redshift data from Visual Studio.
- After configuring the connection, explore the feeds, views, and services provided by the Amazon Redshift Data Source.
- These constructs return live Amazon Redshift data that developers can work with directly from within Visual Studio!
Developer Integration: Databind to Redshift
Connecting Web, Desktop, and Mobile .NET applications with Amazon Redshift is just like working with SQL Server. It is even possible to integrate Amazon Redshift ADO.NET Provider into applications without writing code.
Developers are free to access the Amazon Redshift ADO.NET Provider in whatever way they like best. Either visually through the Visual Studio Winforms or Webforms designers, or directly through code.
- Developers can connect the Amazon Redshift Data Source directly to form components by configuring the object's smart
tags.
- Add a new Data Connection from the Server Explorer and select the Amazon Redshift Data Source. Then, select the
feed, view, or services you would like to connect the object to.
Done! It's just like connecting to SQL Server.
- Once the object is bound to the data source, applications can easily interact with Amazon Redshift data with full
read/write (CRUD) support.
