DS8.7:
Improvements in Xmeta. Significant Performance improvement in Job Open, Save,
Compile etc.
DS9.1:
No Change
2. PX Engine Performance

DS9.1:
No Change
5. Interactive
Parallel Job Debugging
DS8.5:
Not Exist
DS8.7:
Breakpoints with conditional logic per link and node.
(Link -> Rclick -> Toggle Breakpoint)
The running job can be continued or aborted by using multiple breakpoints
with conditional logic per link and node. (row data or job parameter values can
be examined by breakpoint conditional logic)
DS9.1:
No Change
6. Added Vertical
Pivot : Pivot Enterprise Stage
DS8.5:
Extended to current horizontal parallel pivot. Enhanced pivot stage to support
vertical pivoting. (mapping multiple
input rows with a common key, to a single output row containing multiple
columns)
DS8.7:
No Change
DS9.1:
No Change
7. Balance
Optimization :
DS8.5:
Balanced Optimization is that to redesign the job automatically with maximize
performance by minimizing the amount of input and output performed, and by
balancing the processing against source, intermediate, and target environments.
The Balanced Optimization enables to take advantage of the power of the
databases without becoming an expert in native SQL.
DS8.7:
No Change
DS9.1:
Balanced Optimization for Hadoop.
8. Transformer
Enhancements
DS8.5:
Looping in the transformer, Multiple output rows to be produced from a single
input row. 1. New input cache: SaveInputRecord(), GetSavedInputRecord().
2. New System Variables: @ITERATION, @Loop
Count, @EOD(End of data flag for last row).
3. Functions : LastRowInGroup(InputColumn).
4. Null Handling more Options.
DS8.7:
No Change
DS9.1: New Transformation Expressions has
been added. EREPLACE : Function to replace substring in expression
with another substring. If not specified occurrence, then each occurrence of
substring will be replaced.

Stage :
DS8.5:
Not Exist
DS8.7:
Big Data File Stage for Big Data sources (Hadoop Distributed File System-HDFS).
DS9.1: New Enhancement on
1. The IBM Big Data Solution Integrate and
manage the full variety, velocity and volume of data.
