First time user, how to select source in query

[bouteillerAlan]

Hello, I'm trying to use mesh with the following source :

sources:
  - name: sourcea
    handler:
      mysql:
        host: localhost
        port: 3306
        user: root
        password: root
        database: sourcea
  - name: sourceb
    handler:
      mysql:
        host: localhost
        port: 3306
        user: root
        password: root
        database: sourceb

Both of the db have the exact same table in it.

I'm trying to do a request, but I have the count for just one db and not the other :

query MyQuery {
  count_client
}

What I have to do for selecting sourcea or sourceb or both of them ?

In the explorer I just have each table one time without any mention of soucea or sourceb but in the .mesh folder I have the following file :

.mesh
├── index.ts
├── package.json
├── schema.graphql
└── sources
    ├── sourceb
    │   ├── schema.graphql
    │   └── types.ts
    └── sourcea
        ├── schema.graphql
        └── types.ts

In the first schema, no mention of sourcea or sourceb, but just the list of all the table.

EDIT :
Find a solution with transform (https://the-guild.dev/graphql/mesh/docs/transforms/prefix)

sources:
  - name: sourcea
    handler:
      mysql:
        host: localhost
        port: 3306
        user: root
        password: root
        database: sourcea
    transforms:
      - prefix:
          value: sourcea_
          includeRootOperations: true
