Support for upserts?

[Lemmmy]

Currently, it does not look like sequelize-paper-trail supports revisions for upserts (and possibly bulkCreate too?). Would it be possible/feasible to support this, or should I manually do findOne + insert/update? I'm using MySQL.

Paper trail uses sequelize hooks. This is possible setting { individualHooks: true } at bulk operation.

From what I can see, sequelize-paper-trail does not use the before/afterUpsert hooks:

One problem with using { individualHooks: true } is when creating a lot of records in bulk (like you're supposed to). sequelize-paper-trail will try to insert tens of thousands of create revisions one-by-one, which can lead to a large number of inserts failing/timing out due to pool inavailability, etc.

@Lemmmy @ksfreitas any ideas on how to implement it / whether it's worth to implement it?
