This repository (optuna-dashboard) and Goptuna share common code. This pull request may therefore be ported to Goptuna. Make sure that you understand the consequences concerning licenses and check the box below if you accept the term before creating this pull request.

• [x] I agree this patch may be ported to Goptuna by other Goptuna contributors.

What does this implement/fix? Explain your changes.

It is known that the Optuna dashboard seriously slows down to show the list of trials when the number of trials is too large (e.g., N > 100,000). This PR virtualizes the list of trials to accelerate rendering in the dashboard/studies/:id/trials page.

• Note that this PR introduces a dependency on react-virtual.
