Joiner Freezes

Hello, I have a severe Joiner problem. I want to join to csv- Files, each of them with mor than 2,5 Mio. Rows. The Joiner freezes at 30%. . I Use already the cache node in each connection between the csv-file and the Joiner node. I use KNIME 4.2.0, Windows 10, 8,00 GB RAM

Most likely this is a low memory issue. Try to use database to collect CSVs and make join on database level. Or try Garbage Collection

Thank you, I will try it with SQLite.

Hello @dibu,

I suggest trying out the new Joiner (Labs) node available in 4.2. Performance should be better :wink:

Additionally check this (useful) topic about joining:
