Hello everyone,
I am preparing material for a training with OpenRefine and I have a question regarding the size of datasets that can be cleaned... Is there a maximum size? For the moment, I have 242478 rows x 10 columns and it is working well.
Thanks,
Caroline

Allo Caroline, c'est Julie de CQ. La taille est dépendante de la RAM allouée. Tu peux jeter un coup d'oeil à [Installing OpenRefine | OpenRefine](https://openrefine.org/docs/manual/installing#increasing-memory-allocation)
