A place for my thoughts and experiences the Microsoft Data Platform

SSIS Balanced Data Distributor

While surfing the web I’ve stumbled upon an new SSIS Transformation Component just released from Microsoft. The new component is called “Balanced Data Distributor” and it’s available here:

As the page says: “this transform takes a single input and distributes the incoming rows to one or more outputs uniformly via multithreading”.

This could be interesting to apply subsequent transformation in parallel, so that performance can be increased.

Again, from the mentioned link, the documentation says that “The intention of BDD is to improve performance via multi-threading. Several characteristics of the scenarios BDD applies to: 1) the destinations would be uniform, or at least be of the same type. 2) the input is faster than the output, for example, reading from flat file to OleDB.”

Surely Interesting. I just wonder why MS doesn’t announce these kind of releases more loudly. I think I got the news from a tweet (unfortunately I don’t remember the source right now, I saw it some days ago and I just pinned it to my mind), but it would be nice if there would be an official channel where to subscribe to in order not to miss anything. If such channel already exists, please pardon me and point me to the correct direction, thanks Smile.

Btw, before posting this post, I’ve just checked Feedly and found that Boyan Penev wrote an intersting post on this new transformation:
