Performance tips for processing Date Fields:
- Formats with single character are the slowest, for example, YYYY-M-D has single M and D
- Three characters are slow as well, for example, YYYY-MMM-DD
- Use the relevant format for example if the data looks like this 2001-02-01 format YYYY-MM-DD HH:NN:SS.FFF will work but YYYY-MM-DD will be faster
- Special tip for Advanced ETL Processor if the data is already in YYYY-MM-DD HH:NN:SS.FFF format there is no need to convert it
