Hi, Are you using a blocking key in the configuration of the component? If you don't, you' retrying to do 500 000 x 500 000 comparisons. This won't fit in memory and even using the store-on-disk option, it will take days to complete... You must use a blocking key (probably by generating it with the tGenKey component). Have a look at examples at https://help.talend.com/search/all?query=tMatchGroup&content-lang=en The blocking key will partition the data so that the number of comparisons is greatly decreased. See also this documentation https://help.talend.com/search/all?query=tGenKey&content-lang=en about how to tune your tGenKey configuration for a good performance. It's advised to build blocks (aka partitions) of a few tens or hundreds of line. Use the blocking key profile to tune your partitions. Hope this helps.
