> Note: BigQuery has a free tier that you can use to get started without enabling billing. At the time of this writing, the free tier allows 10GB of storage and 1TB of data processing per month. Google also provides a $300 credit for new accounts.
> Note: The size of the tables you query are important because BigQuery is billed based on the number of processed data. There is 1TB of processed data included in the free tier, so running a full scan query on one of the larger tables can easily eat up your quota. This is where it becomes important to design queries that process only the data you wish to explore
> When we look at the results of this, you can see how much data was processed during this query. Writing efficient queries limits the number of bytes processed - which is helpful since that's how BigQuery is billed. Note: There is 1TB free per month
