Each Data Connect operation can perform efficient, complex, multi-table queries or multi-row updates.\n\nCloud SQL no cost trial\n\nIf you accept the default configuration when you provision a Cloud SQL for\nPostgreSQL instance, you will be qualified for a no cost trial for 3 months.\n\n- 5 free trials are available per billing account.\n- 1 free trial Cloud SQL for PostgreSQL instance per project, although you can have multiple non-free instances within that project.\n- The default configuration of your Cloud SQL for PostgreSQL instance is equivalent to a [db-f1-micro instance](https://cloud.google.com/products/calculator?dl=CiRhNDU2NjBmOC1lODJiLTQ0NTctOTliNy00ZmEyZDAyYWFjYTMQBxokODA2Q0I5NzUtMTNEMC00QURFLTg5MUUtMDI2M0VGNzFBMDI0&e=13802955) that has 1 vCPU, 10 GB of storage, 628.74 MB of memory.\n\nDuring the no cost trial, you can add computing resources to your Cloud SQL\ninstance, set up a private IP for your instance, and create a read replica for\nyour instance, at which point you will be billed according to\n[Cloud SQL pricing](https://cloud.google.com/sql/docs/postgres/pricing).\n\nAfter 3 months, pricing starts as low as $9.37 / month. Pricing varies based on\nregions and configurations. See [Cloud SQL pricing](https://cloud.google.com/sql/docs/postgres/pricing).\n| **Note:** Existing customers who participated in the Public Preview trials will automatically roll into the 3 month no cost trials when General Availability starts.\n| **Note:** If you delete your no cost trial instance, your no cost trial for the associated Firebase project will terminate immediately.\n\nVertex AI embedding generation\n\nUsing Data Connect with [Vertex AI](https://cloud.google.com/vertex-ai)\nwill incur standard usage charges from Vertex AI for embedding generation.\n\nManage spending\n\nTo monitor your Data Connect usage, to access an overall view of all\nservice activity, and links to analyze individual service activity, open the\n[Data Connect product page](//console.firebase.google.com/project/_/dataconnect).\nUse the dashboards to gauge your usage over different time periods.\n\nTo track your Data Connect costs, create a monthly budget in the\nCloud console. Budgets won't limit your usage, but you can set\nalerts to notify you when you're approaching or exceeding your planned costs for\nthe month.\n\nTo set a budget, in the Cloud console, go to the\n[Billing](https://console.cloud.google.com/billing/)\nsection and create a budget for your Cloud Billing account. You can use the\ndefault alert settings or modify the alerts to send notifications at different\npercentages of your monthly budget.\n\nLearn more about [setting up budgets and budget alerts](//firebase.google.com/docs/projects/billing/avoid-surprise-bills#set-up-budget-alert-emails)."]]
