Hi Vijay,
You can do it by setting the 'No. of readers per node'
property value to >1. When you do this there will be n No.
of readers created in the node and each reader will read a
block of data from the sequential file.
If you have multiple input files (pattern), you can set the
property 'Read from multiple nodes' to 'yes'.
These 2 properties of sequential files are mutually
exclusive.
