Users are not meant to implement an
PartitionManager. Users are expected to choose existing implementations of this interface, instantiate it, and pass it to the constructor ofEventProcessor.To get started, you can use the
InMemoryPartitionManagerwhich will store the relevant information in memory. But in production, you should choose an implementation of thePartitionManagerinterface that will store the checkpoints and partition ownerships to a durable store instead.Implementations of
PartitionManagercan be found on npm by searching for packages with the prefix @azure/eventhub-checkpointstore-.
