      • createReader

        public <T> EventStreamReader<T> createReader​(java.lang.String readerId,
                                             java.lang.String readerGroup,
                                             Serializer<T> s,
                                             ReaderConfig config)
        Description copied from interface: EventStreamClientFactory
        Creates (or recreates) a new reader that is part of a ReaderGroup. The reader will join the group and the members of the group will automatically rebalance among themselves. In the event that the reader dies, the method ReaderGroup.readerOffline(String, Position) should be called, passing the last position of the reader (Usually done by storing the position along with the output when it is processed.) Which will trigger redistribute the events among the remaining readers.

        Note that calling reader offline while the reader is still online may result in multiple readers within the group receiving the same events.

        Specified by:
        createReader in interface EventStreamClientFactory
        Type Parameters:
        T - The type of events.
        Parameters:
        readerId - A unique name (within the group) for this reader.
        readerGroup - The name of the group to join.
        s - The serializer for events.
        config - The reader's configuration.
        Returns:
        Newly created reader object that is a part of reader group
