IBM Informix and EntityFrameworkCore

Walk-Through

Just recently I needed to explore how I could get IBM Informix and EntitiyFrameworkCore to work together with an existing database, and therefore decided to document my findings in this simple step-by-step walk-through.

Prerequisites

As mentioned here, the IBM® Data Server Provider for .NET IBM DB2® provider option is now the preferred Informix® provider for developing new applications.

Looking at the related site for the IBM Data Server Provider for .NET, it actually states that the former Informix specific provider (IBM.Data.Informix) is now deprecated.

IBM.Data.Informix.dll is deprecated

Although this statement actually applies to the provider for .NET, … more

.NET for Apache Spark – Stream to SQL Server

In this article I am going to describe how to use .NET for Apache Spark with EntityFrameworkCore to stream data to a Microsoft SQL Server. If you have tried this before, you probably stumbled upon the following exception: Microsoft.Data.SqlClient is not supported on this platform.

So let’s find out, how that can be fixed.

Preparation

If you want to stream to an SQL Server, you obviously need to have access to an SQL Server instance first.

Using docker, it is very easy to fire up a related container. I’ve just named it sqlserver, as … more

.NET for Apache Spark ForeachWriter & PostgreSQL

.NET for Apache Spark IForeachWriter implementation

Introduction

A couple of months ago I’ve described how to transfer data from Apache Spark to PostgreSQL by creating a Spark ForeachWriter in Scala.

This time I will show how this can be done in C#, by creating a ForeachWriter for .NET for Apache Spark.

To create a custom ForeachWriter, one needs to provide an implementation of the IForeachWriter interface, which is supported from version 0.9.0 onward. I am going to use version 0.10.0 in this article, however.

Documentation of the C# Interface is provided within the related source code:

https://github.com/dotnet/spark/blob/master/src/csharp/Microsoft.Spark/Sql/ForeachWriter.cs

The example project I am … more
