Several publisher samples are available that demonstrate LiveView embedded publishers. Load these samples in Studio and explore their README files to learn more:

  • LiveView Publisher Sample (publisher, no recovery)

  • LiveView EMS Recovery Sample (publisher and recovery)

  • LiveView FTL Recovery Sample (publisher and recovery)

  • LiveView Kafka Recovery Sample (publisher and recovery)
