MQTT V3 Plug-in Reference

"databaseConnectionString"

• String
• Optional
• Defaults to "FAIRCOMS@localhost"

  This is the database that runs on the same computer as the FairCom MQTT Broker.

This is the connection string for the database instance where data will be stored for this topic.

• It provides great flexibility for the location of the database.
• It allows you to rename the FairCom database instance.
• It allows you to store data in a FairCom database instance running on a remote computer.
• It allows you to store data in one of several database instances running on the same computer.

  FairCom supports running multiple database instances on the same computer.

"AlterPersistenceTopic" cannot change the database connection string.

To move data persistence to another database instance, you must delete the Persistence Topic and create a new one.
