Description

Hello all,
I was looking into https://issues.apache.org/jira/browse/ZEPPELIN-463
I am currently facing a similar issue, basically the browser freezes when displaying more than 5k rows.
The JS starts saying:
Handling of 'wheel' input event was delayed for 1971 ms due to main thread being busy. Consider marking event handler as 'passive' to make the page more responsive.
vendor.ad32e609e9466e7a.js:327 Handling of 'wheel' input event was delayed for 2293 ms due to main thread being busy. Consider marking event handler as 'passive' to make the page more responsive.
vendor.ad32e609e9466e7a.js:327 Handling of 'wheel' input event was delayed for 2582 ms due to main thread being busy. Consider marking event handler as 'passive' to make the page more responsive.

Which makes the UX very unpleasant. This issue would be to address this by simplying adding a LIMIT X (where x is a defined amount) to all queries, only when using the table.
Another request could address pagination.

What do you say? How should I start?

Thanks, regards,
