Is your feature request related to a problem?

When I upload over 900 PDF documents at once, the browser freezes for a long time (the latest version of Firefox). 

When uploading 60 files at once, all documents will be started together instead of automatically starting parsing batch by batch.

Describe the feature you'd like

Support uploading thousands of documents at once and optimize the parsing process.
