iex>     msgs |> Enum.map(&{:ack, IO.inspect(&1)})
iex>   end
iex> end

iex> PulsarEx.start_consumers("test-topic", "test-subscription", ExampleCallback)
iex> PulsarEx.stop_consumers("test-topic", "test-subscription")

Available pulserl options:

consumer_name :: string()

priority_level :: non_neg_integer(),

Only works in shared/failover subscription

properties = [] :: keyword() | %{term() => term()}

initial_position = :latest :: :latest | :earliest

subscription_type = :shared :: :shared | :failover | :exclusive | :key_shared

queue_size = 1000 :: non_neg_integer()

acknowledgments_send_tick = 100 :: non_neg_integer()

max_pending_acknowledgments = 1000 :: non_neg_integer()

queue_refill_threshold :: non_neg_integer(),

When to get next batch of messages from broker, default to half of the queue_size

acknowledgment_timeout = 0 :: non_neg_integer(),

Timeout for sending acknowledgments, 0 means infinity.

If any, must be greater than 1_000(1 second)

nack_message_redelivery_delay = 60000 :: non_neg_integer(),

Redeliver delay for nack'ed messages

dead_letter_topic_name :: string()

dead_letter_topic_max_redeliver_count = 0 :: non_neg_integer(),

Max number of times nack'ed messages can be redelivered0 means infinity

Available PulsarEx options:

callback_module,

The module that implements PulsarEx.ConsumerCallback

batch_size = 1 :: non_neg_integer(),

Always consume the messages in batch, indicate the size of each batch, defaults to 1

poll_interval = 100,

How often to poll next batch, defaults to 100 milliseconds

workers = 1,

Number of workers to work on messages, default to 1.

Note in the case of consuming from partitioned topics and with key_shared subscription,

workers is set to be the same as number of partitions
