Out of memory with taggregaterow

Hello,
I have an issue with the component taggregaterow.
It takes too much memrory, and i would like to know if you have a tips about it.
I import a big file with 3 columns: Customer - Household
i need to check if i don't have a same Customer in different hosehold
For that i use the taggregaterow then tmap with filter (see attach files)
but that takes too much memory, and job is failed
any idea to reduce the memory used?
thanks a lot

Hi,
I think tMap is the component which consume too much memory.
See this KB article outOfMemory

Hi,
The reference is on Talend Help Center and you are welcome to use your forum ID or register a new account freely. In addition, for a large set of data, try to store the data on disk instead of memory on tMap.
See my screenshot

About my issue, i resolved the Tmap problem, in replacing it by a tuniqrow.
But still have an issue with the taggregaterow to count the number of custmer_id per household and export it in sql table, it takes all the memory
If you have an idea?
thanks

Hi,
Perhaps Allocating more memory to the Talend Studio is a good option for your case.
