I am trying to build a Destinatino adapter whose error output can be something apart from integer(errocode and index). How can we proceed with that?

It's pretty clear,pls give definition for Blocking,non-blocking or semi-blocking definition.

I am just trying to understand how it's behave in the sql server engine.

please excuse if i am wrong.

Awesome article. Probably you could create a package with one of the blocking, non blocking and semi blocking transformations and explain as to what exactly is happening @ runtime for each of the transformations.

The multicast component is partially blocking, not non-blocking.

Chielus said:

Also, the script component can be either of the 3 i think?

waseem said:

HI,

Let say i have first name and last name as my input column but i m passing Name i.e  first name + last name  as  a  single  record (by concatanatin).So in this my  expression is recieving 2 inputs but  one  output.So can u please xplain why still expression is non blocking

March 19, 2013 12:47 PM
 

Thiru said:

Hi Waseem,

No of records IN== No of records out   (i.e 10(Firstname+Lastname)=10 Name)  So 10 input records 10 output records

Thanks for the wonderful post.

Any idea why “Row sampling” is blocking task whereas “Percentage sampling” is non-blocking?

Lot of Ads in Site area ppearing over content in the website. Can you please move ads to other places so that content should be clearly visible.

Little confusion

for Synchronous Row input = Row output

Then how Percentage Sampling can be Synchronous

vivek raj said:

Is union all is semi-blocking transformation? I think it is non-blocking transformation because it does not need another buffer to store result.

Excellent Article

Mike T said:

That's really interesting, considering it reverses the customary meaning of synchronous and asynchronous.  Typically calls that are synchronous are blocking calls.

Very basic but powerful explanation nice job

GOPI said:

You mentioned, All source adapters are asynchronous(two outputs) but you mentioned Lookup , multi cast(these will have more outputs..matched/non matched..etc) are non blocking transformations. Is not this contradict?
