SSIS custom component performance tidbit

I was helping a friend of mine to debug performance issue with his SSIS package. The package was pretty simple – he needed to read data, shard it using some partitioning scheme, then insert the results into 8 SQL destinations. The hashing algorithm used for partitioning was rather complex for conditional split, so he created…

When April Fools jokes become reality

Couple years ago Charles Petzold wrote about C# Application Markup Language – XML syntax for C#. Go read it if you’ve not seen it yet. Well, it was a fool day’s joke of course (the publishing date at the bottom hints about it). But yesterday, when playing with Windows Workflow Foundation rules, I’ve looked at…
