SpreadStreamProcessing: Stream should be flushed when the content is ready to be written

At this point, CsvWorkbookExporter flushes the data to the underlying stream each time a new data is added. This leads to decreased performance. Ensure the best possible performance by flushing the stream at the end of the content generation.

Hi Grinden,

Thank you for your feedback. As this is an optimization to the product and a change in its behavior, we logged it as a feature request for the component. Nonetheless, it is already implemented and included in our LIB Version 2018.3.1126 from this week.

Regards,

The performance decrease for writing a moderately sized CSV (1.5MB of data) to a local network drive over a 1Gb connection is about 15 minutes vs 2 seconds when AutoFlush is turned off via reflection. I would say this was a bug, not a feature request.
