Exporting exposures takes a long time even in medium-sized Superset instances

[AntonAiven]

I'm not able to export exposures as it always ends up crashing before finishing, even in our testing environment where data is limited.

Is it possible to pararellize the exporting, or at least narrow down the exported exposures to certain types?

hey @AntonAiven,

Do you have any logs/stack traces that could help pointing out to the issue/bottleneck?
