Examples with ConfigException org.apache.samza.config.ConfigException used on opensource projects

Example 1 with ConfigException

use of org.apache.samza.config.ConfigException in project samza by apache.

the class MockCoordinatorStreamSystemFactory method getConsumer.

/**
   * Returns a consumer that sends all configs to the coordinator stream.
   *
   * @param config Along with the configs, you can pass checkpoints and changelog stream messages into the stream.
   *               The expected pattern is cp:source:taskname -> ssp,offset for checkpoint (Use sspToString util)
   *               ch:source:taskname -> changelogPartition for changelog
   *               Everything else is processed as normal config
