API Calls are too slow

Hello, I recently upgraded google-ads-api to version 5.0.3 hoping to overcome all the problems I had with version 4.0.3. The GRPC library used by google-ads-api in version 4.0.3 randomly returned some obscure Stream Removed error, so as soon as I read that the newer version is using a different GRPC library I was keen on upgrading my codebase to the latest version.

Alas, it turned out that this code:

const customer = new Customer(
    clientOptions,
    {
        customer_id: id || process.env.GOOGLE_ADS_CUSTOMER_ID,
        login_customer_id: process.env.GOOGLE_ADS_CUSTOMER_ID,
        refresh_token: process.env.GOOGLE_ADS_REFRESH_TOKEN
    }, 
    {
        onQueryStart({ credentials, query, reportOptions, cancel, editOptions }) {
            console.log("q", query)
        },
        onQueryError({ credentials, query, reportOptions, error }) {
            console.log("err", error);
        }
    }
)

let data = await customer.query('SELECT customer_client.descriptive_name, customer_client.id FROM customer_client')

took about 42 seconds to resolve.

Am I missing something? Why is it so slow?

Thanks

I’ve taken a further look and there are some issues around the GoogleAdsService being very slow to initialise, as it requires all other protos within it. See my reply here as well.

We’re also going to raise the issue with Google.

Glad to hear you have a temporary solution @flasaracina.

You bring up the interesting point about the REST API being much quicker, and it’s something we’ve thought about before. We’ve been quite pro proto/gRPC as Google recommends it and claim that it’s faster, but this hasn’t been the case always, particularly with the new Gapic auto-generated clients.

It could be interesting to think about using REST behind the scenes instead of gRPC in a future major version.
