Parsing data File

Estimated Time:

Why does it take so much time?

While parsing a file, the database has to perform various tasks, some of them needs a lot of CPU and memory for larger files.

• preprocessing: means automatic detection of headlines, table body, format values or csv-separators
• copying: means read the file cell by cell and copy all elements to the database. During this format settings can be calculated (for example iso-time)
• analyzing: check out for different data types (can be time, numeric or text)
