Is BigQuery java api thread safe?

Question

I would like to use BigQuery java api 'com.google.cloud:google-cloud-bigquery' in our project. I am creating service instance like this

BigQuery bq =
        BigQueryOptions.newBuilder()
            .setCredentials(credentials)
            .build()
            .getService();

Should I store this com.google.cloud.bigquery.BigQuery instance somewhere in the app and reuse it for every call? Is it thread safe? What is the recommended way?

Thanks!

I suggest having this as a global variable and reuse it as you may hit a rate limit due to multiple authentication requests. Moreover, if you plan use Threads, I suggest checking the BigQuery API quotas to consider them in your development.

Hope it helps.
