Different flows using a special character

lmit — Wed, 20 Mar 2019 10:53:49 GMT

Hi All,

I have a input file which has a data like
1,a~b~c,xyz

Based on the special character my data should be going into different flows like
1,a,xyz ( as 1st flow if I use tmap component)
1,b,xyz (as 2nd flow )
1,c,xyz (as 3rd flow)

Am not saying about the output which we get tNormalize component where the 3 rows will be in one flow or file

But I want 3 different flows how can I achieve this

Any help would be great

Thanks in advance,
Lmit

Hi,

The easy way is to assign a sequence number for each group and separate the data based on the sequence number value in output section.

In normal case, you will have sequence like below

Numeric.sequence("s1", 1, 1)

But in your case, add your primary key as the factor to determine the sequence. But make sure that id value is in String format.

Numeric.sequence(row1.id, 1, 1)

Once you get a sequence number, you can control the flow by adding filter condition in output by checking the reminder of sequence value. For a three way sequence, you need to take the reminder of row1.seq%3 and check it as 0,1 or 2.

Hi,

I would say, do the split first using tnormalize and then group them.

Hi,

If I group them then I will get all 3 records in one file as they will be having same id

Thanks,
