Each Data Connect operation can perform efficient, complex, multi-table queries or multi-row updates.\n\n### Cloud 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\n### Vertex 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---------------\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)."]]
