I am trying to import an excel file with 4 columns and 106830 rows. After first step, and few minutes of CPU at 100% an exception of java.lang.OutOfMemoryError: Java heap space is raised
hi,
lot’s amount of data can be a problem. In order to narrow down the problem, please see this similar topic: Support large files · Issue #86 · mariodavid/cuba-component-data-import · GitHub
You can instead of using the UI wizard use the DataImportAPI
. Furthermore it heavily depends on the settings that you have configured for the data import. Unique configuration will influence that as well as the Trasaction Strategy.
Please provide the following:
- an minimal example project
- example import configuration
- example import file (CSV e.g.)
then I can take a look into it.
Thanks
Cheers
Mario
