--------------------------------------
Summary: Enabling downloading more rows with Download Data as CSV
Key: ZEPPELIN-2487
URL: https://issues.apache.org/jira/browse/ZEPPELIN-2487
Project: Zeppelin
Issue Type: Improvement
Affects Versions: 0.7.1
Reporter: Paul Brenner
There are limits to how much data the download to csv button will download
which limit Zeppelin’s usefulness for our BI teams. In Chrome the limit is
either 1.5MB or 3500 rows. In Firefox it is possible to download 100k rows,
however the web interface slows to a crawl.
Although most users fluent in whatever language they are working with would
just export 100k rows directly to csv (e.g. via df.write.csv() in spark), if
Zeppelin is going to be a BI tool useful to analysts it is important to include
a way to export more data to csv via the web app.
Would it be possible to include a way to download more data (perhaps up to 100k
rows if we need a limit) without showing all the rows on screen? Hue is able to
do this by only loading data as it is scrolled through. If that is too complex
perhaps just add an option to download all of the data sent to z.show even
though z.show is limited to showing 1000 rows.
Discussion on the users list is here:
