I have the following quetion.

Let's say I have the unstable_cache function for checking if an onboardingSurvey was filled by a user:

It accepts:

1) user_id which is added to the cache keyParts as well as the hasCompletedOnboardingSurvey
2) I create the tag to revalidate based on the function name hasCompletedOnboardingSurvey

  const hasCompletedOnboardingSurvey = unstable_cache(
    async ({ userId }: { userId: string }) => {
      const onboardingSurveysData = await db
        .select({
          id: onboardingSurveys.id,
        })
        .from(onboardingSurveys)
        .where(eq(onboardingSurveys.userId, userId))

      return onboardingSurveysData.length > 0
    },
    ['hasCompletedOnboardingSurvey'],
    {
      tags: ['hasCompletedOnboardingSurvey'],
    },
  )

When a user clicks the don't show button in a client component, I am running the following server action, where I call revalidateTag('hasCompletedOnboardingSurvey'):

async function saveOnboardingSurvey({
  data
}: {
  data: TForm
}) {
  'use server'

  const user = await getUser()

  await db.insert(onboardingSurveys).values({
    ...data,
    userId: user.id,
    createdAt: new Date(),
  })

  revalidateTag('hasCompletedOnboardingSurvey')
  redirect('/campaigns')
}

My current understanding is that this will invalidate the cache for ALL USERS since I cannot pass in the userId as a tag. Is this correct? How would I be able to only revalidate the data cache for a specific user and not every user?

Thanks 🙏
