How to do a bulk update in Firestore

Any of those help Turns out a special table named excluded contains the row-to-be-inserted (strange name though)

insert into USERS(
    id, username, profile_picture)
select unnest(array['12345']),
    unnest(array['Peter']),
    unnest(array['someURL'])
on conflict (id) do 
update set
    username = excluded.username,
    profile_picture = excluded.profile_picture;

will help you Option 1 is clearly the least performant both in terms of memory requirements and computing needs. You'll need to 1) query all records from your primary data source, 2) query all records from Elasticsearch, 3) figure out the diff and 4) bulk update all records in Elasticsearch again. As time goes, your primary data source will always contain approximately the same number of records, but the number of records in ES will grow since you have new records in your snapshot that are not in Elasticsearch and also records that will need to be deleted from Elasticsearch, which means that step 2 above will retrieve more and more documents each time.
With option 2 you'll need to 1) query all records from your primary data source, 2) bulk index them, 3) then query Elasticsearch for the records that weren't updated and 4) bulk update them in Elasticsearch again. This is not my preference either for the same reason as for option 1, i.e. your Elasticsearch index will keep growing.

will help you I believe you're just after promise chaining with then? The first line should return a promise - so just call then on the result:

return sequelize.transaction(function(t){
  return sequelize.Promise.each(arrToUpdate, function(itemToUpdate){
    model.update(itemToUpdate, { transaction: t })
  }).then((updateResult) => {
    return model.bulkCreate(itemsArray, { transaction: t })
  }, (err) => {
    // if update throws an error, handle it here.
  }); 
});

I hope this helps . You can add a FailureListener and it will tell you what's wrong in logcat.

db.collection("user").document(uid).set(data).addOnCompleteListener(new OnCompleteListener<Void>() {
    @Override
    public void onComplete(@NonNull Task<Void> task) {
        if (task.isSuccessful()) {
            Toast.makeText(getApplicationContext(), "Data Added", Toast.LENGTH_SHORT).show();
        } else {
            Toast.makeText(getApplicationContext(), "There was some problem", Toast.LENGTH_SHORT).show();
        }
    }
})
.addOnFailureListener(new OnFailureListener() {
    @Override
    public void onFailure(@NonNull Exception e) {
        Log.w(TAG, "Error writing document", e);
    }
});

hope this fix your issue If you want to log an object with JavaScript, don't call toString() on it. Just pass it directly:

console.log(data!)

console.log(data!.bJaE...7eC2.referencia)
