Are Data import handlers more performant than regular updates

[ufuk yılmaz <uy...@vivaldi.net.INVALID>]

Hello all,

I am working on reindexing a large collection, getting data from solr, processing it a bit (adding a few fields, transforming a few) and sending it to another collection through update handler.

I was reading about data import handlers and SolrEntityProcessor. Is it more performant/better than regular indexing with http requests to update handler, or does it use the same mechanisms under the hood as the regular update handler and only exist as a convenience?
