Hi Zeppelin team!
I have been working on an interpreter for zeppelin that connects to MS SQL
Server. It is pretty much finished, but I had some questions as to the
scalability of Zeppelin and how to contribute.
Recently I ran a select statement that pulls in ~45,000 rows from SQL Server.
Afterwards the application was extremely sluggish in its performance (on
chrome) and it would crash (on internet explorer). I was hoping you could help
me pinpoint where these problems occur so that I could see if I could help make
Zeppelin more scalable.
Internet explorer would say there were "long running scripts" which were making
it sluggish, and when I was debugging I also saw that actions like trying to
"persist" or "save" the note were taking a while. I also wonder whether the
renderTable function in paragraph.js could be the culprit that is slowing
everything down since it uses a lot of string concatenation. These are just
starting points of what might be slow, I am still new to zeppelin so I am
hoping that with your experience you will have a better understanding of what
could be going wrong.
Looking forward to working with you,
Andres
