Hi Moon,
Some of my requirements.
1. Can we achieve better memory management for notebooks ? I'm also
facing some similar OOM issue, like Dafeng mentioned in other
discussion.I'm using the iframe view of a paragraph, can we load that
code+results to memory only when requested ? I think this is one area to be
focused on.
2. In table/graph view can we include below features along with
pagination ?
a) Search , similar to
https://docs.angularjs.org/api/ng/filter/filter
b) Sorting of columns. Also custom sorting algorithms ?
Also any idea on GA for these suggested improvements ?
Regards
Shabeel
