tDataShuffle - generating duplicate values

Anonymous — Thu, 13 Dec 2018 17:28:15 GMT

Hi,

I have a 5 independent unique columns and I am doing tDataShuffling on the 4 fields with Group ID 1 to 5.

The result is giving me rows - with duplicates with 2 of the columns.

Example:

Field1(type - String 15) = 1,2,3,4,5,6 - group 1

Filed2(type - Binary Decimal 15) = 11,12,13,14,15,16 - group 2

Field3(type - String 30) = 21, 22, 23, 24, 25, 26 - group 3

Field4(type - String 30) = 31, 32, 33, 34, 35, 36 - group 4

Field5(type - Binary Decimal 10) = 41, 42, 43, 44, 45, 46 - group 5

Expected: (shuffle independently)

Field1 = 2,3,5,1,6,4

Filed2 = 13,11,14,16,15,12

Field3 = 26, 25, 24, 23, 22, 21

Field4 = 35, 36, 34, 33, 31, 32

Field5 = 44, 41, 46, 43, 42, 45

Actual output:

Field1 = 2,3,2,1,6,4

Filed2 = 13,11,14,16,15,12

Field3 = 26, 25, 24, 26, 22, 21

Field4 = 35, 36, 34, 33, 31, 32

Field5 = 44, 41, 46, 43, 42, 45

I see the duplicated created are in String type or group 1 & 3.

The random generator and buffer size are of default value.

Please advice.

Thanks

Hello,

Could you please clarify in which Talend version/edition you are?
