The connection fields are described below.

Basic​

  • Name: The display name of the database in Canner Enterprise. You can change it later.
  • Data Source Type: The database type. Select MongoDB.

Data Source Properties​

  • URL: The database address, in the format <hostname>:<port>.
  • Username: The username used to connect to this MongoDB database.
  • Password: The password used to connect to this MongoDB database.
  • Database Name: The name of the database to connect to.
  • Auth Source: The Auth Source (authentication database) in your MongoDB deployment, used to verify the credentials you provide. The Auth Source is usually admin.
  • TLS (off by default): Turn this on to connect using TLS/SSL.
  • Schema sampling strategy: Canner Enterprise samples your table schema to infer a structured format. Choose the sampling method:
    1. From First (default): Sample starting from the first document.
    2. From Last: Sample starting from the last document.
  • Schema strategy sample size: The number of documents to sample.
  • Explore Timeout: The timeout for connecting to the data source. If connecting takes longer than this, the system stops and shows a connection error. The default timeout is 5000 ms. If the database you are connecting to has many tables, consider increasing this timeout.

Step 3: Finish​

After you submit, the MongoDB data source appears in the sidebar shortly. Click it to open the data source details page.
