Is it possible for mautic to query multiple databases and cross-check their results during the same processing.

Probably not out of the box. What are you trying to achieve?

I’m trying to apply a segmentation on contacts from a BigQuery database and then with that result send it to the mautic’s databse which is mySql ( where the cross-checking applys ). So that i can apply a campaign on them.

You need to create the plugin, that reads the second database.
Most simple way is to create an import, or set up a custom, automated import using the custom imports plugin:

> Custom Import for Mautic. Contribute to mtcextendee/mautic-custom-import-bundle development by creating an account on GitHub.
You can also use webhooks to populate data from other databases.
Or the most hacky would be to set up a conversion table, here is a tutorial:
> **[Add new functionality to your Mautic with a conversion table (2 case studies)...](https://joeykeller.com/add-new-functionality-to-your-mautic-with-a-conversion-table-2-case-studies/)**
You can of course create a plugin as well.
