Question { IBM, 16974 }

how does deadlock occur?

Answer

It is the condition, where the graph will stop processing
due to mutual dependency of data.

For Ex:

Let’s consider a concatenate component, having three
inputs. Let’s say first i/p receives 20 million records,
second i/p receives 1000 records, third i/p receives 500
records.
Now even though the concatenate receives i/p’s at second
and third i/p port, the concatenate won’t work until it
receives all the i/p’s at it’s first i/p port. So the
graph’ll stop processing until the first i/p port receives
all its data. This condition is called DEADLOCK.

This is now minimised (not prevented) by “Automated flow
buffering”. This will in turn provide more workspace in
network resource allocation. So that the processing’ll be
faster.

The Automated flow buffering is available from 1.8 version.

What is the difference between Generate Records Component
and Create Data Component?

Answer

There is no transform function in Generate Record comp.
Therefore it will create data's defaultly of it's own,
according to the dml defined. To change that data, we have
to connect some other component after Generate Record comp.
and have to modify. Whereas, in Create Data comp. we can
write a transform function, so that the data's are
generated as per out trfm function. Also index is defaultly
defined in Create Data comp.
