6. Apache Pulsar is a Cloud-Native
Messaging and Event-Streaming Platform.

7. Why Apache Pulsar?
Unified
Messaging Platform
Guaranteed
Message Delivery Resiliency Infinite
Scalability

8. Component Description
Value / data payload The data carried by the message. All Pulsar messages contain raw bytes, although
message data can also conform to data schemas.
Key Messages are optionally tagged with keys, used in partitioning and also is useful for
things like topic compaction.
Properties An optional key/value map of user-defined properties.
Producer name The name of the producer who produces the message. If you do not specify a producer
name, the default name is used. Message De-Duplication.
Sequence ID Each Pulsar message belongs to an ordered sequence on its topic. The sequence ID of
the message is its order in that sequence. Message De-Duplication.
Messages - the basic unit of Pulsar

9. Connectivity
• Libraries - (Java, Python, Go, NodeJS, WebSockets,
C++, C#, Scala, Rust,...)
• Functions - Lightweight Stream Processing (Java,
Python, Go)
• Connectors - Sources & Sinks (Cassandra, Kafka, …)
• Protocol Handlers - AoP (AMQP), KoP (Kafka), MoP
(MQTT)
• Processing Engines - Flink, Spark, Presto/Trino via
Pulsar SQL, NiFi
• Data Offloaders - Tiered Storage - (S3)

23. Pulsar Subscription Modes
Different subscription modes
have different semantics:
Exclusive/Failover - guaranteed
order, single active consumer
Shared - multiple active
consumers, no order
Key_Shared - multiple active
consumers, order for given key

26. Messaging
Ideal for work queues that do not
require tasks to be performed in a
particular order—for example, sending
one email message to many recipients.
RabbitMQ and Amazon SQS are
examples of popular queue-based
message systems.

.. and Streaming
Works best in situations where the order
of messages is important—for example,
data ingestion.
Kafka and Amazon Kinesis are examples
of messaging systems that use streaming
semantics for consuming messages.

Topic
Producer 1
Producer 2
● Producers send messages.
● Topics are an ordered, named channel that producers
use to transmit messages to subscribed consumers.
● Messages belong to a topic and contain an arbitrary
payload.
● Brokers handle connections and routes
messages between producers / consumers.
● Subscriptions are named configuration rules
that determine how messages are delivered to
consumers.
● Consumers receive messages.

32. Producer-Consumer
Producer Consumer
Publisher sends data and
doesn't know about the
subscribers or their status.
All interactions go through
Pulsar and it handles all
communication.
Subscriber receives data
from publisher and never
directly interacts with it

35. Pulsar Functions
● Lightweight
computation similar to
AWS Lambda.
● Specifically designed to
use Apache Pulsar as a
message bus.
● Function runtime can
be located within
Pulsar Broker.
A serverless event streaming
framework

36. streamnative.io
● Consume messages from one
or more Pulsar topics.
● Apply user-supplied
processing logic to each
message.
● Publish the results of the
computation to another topic.
● Support multiple
programming languages (Java,
Python, Go)
● Can leverage 3rd-party
libraries to support the
execution of ML models on
the edge.
