In Duplicate Stages we have more number of optionscompare
to sort while removing duplicates.If you have less number
if data you can go with Sort stage to remove duolicats.If
you have large number of data go for Remove Duplicates
Stage.

Answer / phani kumar

Sort stage is used to sort the data and having option of
identifying the duplicate records with the value of Key
change column. But, to perform sort and remove duplicates is
leads to decrease the performance. So, it is preferable for
less amount of data.

Remove duplicates stage is used to get only unique records
either first occurrence or last occurrences. For large
amount of data, sorted data is required for better performance.

Correct me if iam wrong..........

Answer / data master

Sort Stage do Sorting of data and performing Remove
Duplicate records, which will slow the performance of job
(Hence it is better to sort data at database level).

If the data is already sorted than use the Remove Duplicate
Stage to remove duplicate records, Which will give better
performance of job than above situation.

Answer / swati

In Remove Duplicate stage you will get only unique records.

In sort Stage you will get both unique and duplicate records based on key change column.

create a job that splits the data in the Jobs.txt file into four output files. You will direct the data to the different output files using constraints. • Job name: JobLevels • Source file: Jobs.txt • Target file 1: LowLevelJobs.txt &#8722; min_lvl between 0 and 25 inclusive. &#8722; Same column types and headings as Jobs.txt. &#8722; Include column names in the first line of the output file. &#8722; Job description column should be preceded by the string “Job Title:” and embedded within square brackets. For example, if the job description is “Designer”, the derived value is: “Job Title: [Designer]”. • Target file 2: MidLevelJobs.txt &#8722; min_lvl between 26 and 100 inclusive. &#8722; Same format and derivations as Target file 1. • Target file 3: HighLevelJobs.txt &#8722; min_lvl between 101 and 500 inclusive. &#8722; Same format and derivations as Target file 1. • Rejects file: JobRejects.txt &#8722; min_lvl is out of range, i.e., below 0 or above 500. &#8722; This file has only two columns: job_id and reject_desc. &#8722; reject_desc is a variable-length text field, maximum length 100. It should contain a string of the form: “Level out of range: <min_lvl>”, where <min_lvl> is the value in the min_lvl field. My Question is how do you write the stage variable for reject rows.
