Configuring Tiered Storage in Apache Pulsar
The tiered storage feature of Apache Pulsar enables long-term retention of messages by transparently leveraging cost-effective storage systems like cloud storage. This tutorial demonstrates how to configure Pulsar tiered storage to use Amazon S3.
Using Pulsar Functions: Log Topics
Streamlio's Sanjeev Kulkarni demonstrates how to use log topics from within Pulsar Functions to aid in monitoring and troubleshooting your functions.
Using Pulsar Functions: Runtime Parameters
Streamlio's Sanjeev Kulkarni explains how to use pass parameters into an Apache Pulsar Function and provides a live code demo of an example.
Using Pulsar Functions: Composing Functions
Streamlio's Sanjeev Kulkarni explains how you can connect the output of one Pulsar Function to the input of another to perform a sequence of processing steps in this video example.
Introduction to Pulsar Functions, Part 2
Streamlio's Sanjeev Kulkarni explains how to write a Pulsar Function and illustrates how to deploy that function to a Pulsar cluster using a simple example function.
Introduction to Pulsar Functions, Part 1
Streamlio's Sanjeev Kulkarni explains the motivation for the creation of Apache Pulsar Functions and how they differ from other approaches to stream processing.
Unified queuing and streaming: Part 2
In this video Sanjeev Kulkarni of Streamlio discusses a retail use case that would need both queuing and streaming. He whiteboards how Apache Pulsar is uniquely able to handle both use cases within one distributed messaging system.
Unified queuing and streaming: Part 1
In this short video, Sanjeev Kulkarni and Christian Hasker of Streamlio discuss the differences between queuing and streaming. Apache Pulsar, the next generation distributed pub/sub system is unique in that it can handle both queuing and streaming use cases. Sanjeev presents a definition of each, and explains when it would make sense to use one vs the other.
Migrating an Apache Kafka application to Apache Pulsar with no code changes
In this 201 level video, Sijie Guo of Streamlio demonstrates how to migrate an existing Kafka application to Apache Pulsar with no code change using the Kafka API wrapper. It can be used to migrate an application to take advantage of next generation messaging features in Pulsar such as multi-datacenter support, multi-tenancy, strong durability guarantees, and unified messaging and queuing architecture.
Install Apache Pulsar and get up and running in 4 minutes
Development 101 series: in this quick 4-minute video, Sanjeev Kulkarni shows you how easy it is to download, install and get Apache Pulsar up and running on your laptop. For more information on Apache Pulsar visit streaml.io or the project at pulsar.apache.org.
Running Heron on Google Kubernetes Engine
In this hands-on demo, Chris Kellogg, engineer at Streamlio, shows how easy it is to set up the Heron streaming engine up and get it running on Google Kubernetes Engine, powered by Kubernetes.
How Apache Pulsar uses Apache BookKeeper to store topics
In this expert developer whiteboard session Ivan Kelly, Apache BookKeeper PMC member and engineer at Streamlio, discusses how Apache Pulsar uses Apache BookKeeper to store replicated logs for hundreds of thousands of topics.
Message guarantees in Apache Pulsar with Apache BookKeeper
In this expert developer whiteboard session Ivan Kelly, Apache BookKeeper PMC member and engineer at Streamlio, discusses what happens to a message when it enters Apache Pulsar and the guarantees that are provided.
Experiences in production with Heron
In this video, Karthik Ramasamy, co-creator of Heron while working at Twitter and now co-founder of Streamlio, talks about lessons learned running Heron in production at massive scale at Twitter. He also presents feedback regarding common issues in development. While the presentation is Heron specific, these lessons can be applied to other streaming systems as well.
How Apache Pulsar stores cursors using Apache BookKeeper
In this expert developer whiteboard session, Ivan Kelly, PMC member of Apache BookKeeper and engineer at Streamlio talks about cursor management. This is very hard for other messaging systems to do but is no sweat for Apache Pulsar, which leverages Apache BookKeeper. Make sure to read Ivan's blog post on the subject at [streaml.io/blog](https://streaml.io/blog).
Introduction to the Heron Stream Processing Engine's Architecture
In this video Karthik Ramasamy, co-creator of Twitter Heron, and co-founder of Streamlio, presents an overview of the design goals for the Heron stream processing engine. He also looks at the overall architecture of Heron, which has been used in production at Twitter for 3 years.
Multi-tenant Messaging with Apache Pulsar (and Monopoly!)
In this quick video tutorial (using Monopoly) we'll take a look at the multi-tenant capabilities in the Apache Pulsar (incubating) messaging system. Pulsar was designed as an enterprise grade solution to meet the following requirements at Yahoo:
* Ensure that strict SLAs are met
* Guarantee isolation between tenants
* Enforce resource utilization quotas
* Provide per-tenant and system-wide security
* Ensure low-cost operations and simpler manageability
Introduction to the Apache Pulsar Messaging System
This short demo shows you how to easily get up and running with Apache Pulsar. Apache Pulsar is an open-source distributed pub-sub messaging system originally created at Yahoo and now part of the Apache Software Foundation. Built from the ground up as a multi-tenant system, it includes support for isolation, authentication, authorization and quotas. With built-in geo-replication and durable storage backed by Apache BookKeeper it is horizontally scalable and can be distributed across multiple data centers.
Pulsar has run in production at massive scale at Yahoo for more than three years, and today powers the message part of the Streamlio platform.
Heron Delivery Semantics, Part 2
In Part 2 Sanjeev Kulkarni, co-creator of Heron and co-founder of Streamlio, examines the difference between effectively once semantics and exactly once semantics in streaming systems. Exactly once is a very expensive mechanism, and often effectively once achieves the same goal.
Heron Delivery Semantics, Part 1
Sanjeev Kulkarni, co-creator of Heron stream processing engine, and co-founder of Streamlio, outlines the different delivery mechanisms supported in Heron. He explains the difference between at most once semantics, at least once semantics, effectively once semantics, and exactly once semantics. These terms can all be very confusing. In Part 1 Sanjeev focuses on at most and at least once semantics. In Part 2 he dives more deeply into effectively once, and exactly once.
Apache Pulsar Concepts and Terminology
Apache Pulsar (incubating) is an enterprise-grade publish-subscribe (aka pub-sub) messaging system that was originally developed at Yahoo. It is one of the core components of the Streamlio end-to-end real-time solution. This whiteboard session introduces the core concepts and terminology needed to work with Pulsar.
Heron Stream Processing Architecture and Terminology
Heron is a real-time stream processing engine, built at and proven in production at massive scale at Twitter. This short video provides an overview of Heron for architects and developers interested in learning about its architecture and terminology.

*Apache Heron is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by Apache Incubator PMC. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
