How do you optimally and efficiently import huge files? I currently have about 50k inserts a second but i am struggling with memory managment. I want to use 1% of the files size as memory in the app what are the ways to achieve this?
One way to efficiently import huge files into a Spring H2 database is to batch process the inserts. Instead of inserting each record individually, you can group multiple records together and insert them in batches. This can significantly reduce memory usage and improve performance.
You can also consider using tools like Apache POI or OpenCSV to read the file in chunks and insert the data into the database incrementally. This allows you to process the file without loading it entirely into memory.
Another approach is to optimize your database configuration for bulk inserts. For example, you can disable indexes and constraints temporarily during the import process and then rebuild them once the import is complete.
Additionally, make sure to monitor your memory usage during the import process and optimize your JVM settings accordingly. You may need to increase the heap size or adjust garbage collection settings to prevent memory leaks.
By implementing these strategies, you should be able to import large files efficiently while managing memory usage effectively.
