How to update a field, and prevent it re-triggers the update subscriber?

[aldo-roman]

Hello Medusa,

I have a use case where I need to trigger a workflow when a product is updated. As part of the workflow, the product is also updated (it re generates the product's tags).

How can I update the product without it re-emitting events?

I found preventReleaseEvents in the shared context, but it seems to be undocumented

Will doing this work?

productModuleService.updateProductTags(productId, {
  value: newTags,
}, {
  preventReleaseEvents: true
})

Alternatively, when subscribing to product.updated, how could I know which fields were updated? This was possible in V1 but couldn't find documentation about it for V2.

Thanks!
