Out of Memory


I think your product is lovely. I am trying to de-dup my customer master records using this tool. I am just using demo version to get the look and feel. When I tried to process 20k records, the tool gave me out of memory exception. So I increased the java heap size to 4096m. Now I am able to process 50k records in de-duplication task but when I connect the merge task, I am again getting out of memory exception.

Any thoughts?

That sounds extreme for so few records. Are the records very large, or are your criteria very wide so they end up as only a very few groups (very large groups are rather expensive, memory-wise)?
