This submission appears to read more like an advertisement than an entry in an encyclopedia. Encyclopedia articles need to be written from a neutral point of view, and should refer to a range of independent, reliable, published sources, not just to materials produced by the creator of the subject being discussed. This is important so that the article can meet Wikipedia's verifiability policy and the notability of the subject can be established. If you still feel that this subject is worthy of inclusion in Wikipedia, please rewrite your submission to comply with these policies. | |

Comment: There is not enough independent, significant coverage here. Please read the advice. WikiOriginal-9 (talk) 17:44, 8 November 2023 (UTC)
- Comment: The majority of the references are primary sources, please cite secondary sources. Also, YouTube and Github are not reliable sources. Additionally, some paragraphs remained unsourced, please cite reliable, secondary sources! Tails Wx 14:08, 8 November 2023 (UTC)
- Comment: So many unreferenced sections, also promotional. Vanderwaalforces (talk) 12:56, 8 November 2023 (UTC)

Apache Pulsar is a cloud-native, distributed messaging and stream-processing platform.[4] [5][6]
It provides scalable, durable, and secure messaging and stream processing that aims to handle high-throughput use cases such as event-driven architecture, real-time analytics, and data integration.[7][8]
Pulsar covers both message queue and publish-subscribe (pub-sub) use cases.[9][10][6]
Pulsar is an open-source project by Apache Software Foundation and written in Java.
There are client libraries for several programming languages, including Java, C++, Go, .NET, Node.js, Python, and Rust.
History[edit]
Apache Pulsar was developed by Yahoo! in 2014. It was first released as an open-source project in 2016.[11] Apache Pulsar becomes Top-Level project[12][13] [14]
Architecture[edit]
Apache Pulsar adopts a segmented architecture that separates the serving layer from the storage layer.[15] This separation allows for independent scaling of processing and storage, providing flexibility and better resource utilization.[6][16]
Pulsar Cluster components:
- Brokers: Stateless components that handle client connections and manage the dispatch of messages to consumers.[17]
- Bookies: A bookie is a node of Apache BookKeeper, a scalable, fault-tolerant, and low-latency storage service optimized for append-only workloads. It's responsible for storing messages on disk.
- Distributed metadata store: Used for coordination and metadata storage among different Pulsar components.
A set of multiple Pulsar clusters can be connected as a single Pulsar Instance. It is often used for geo-replicating data across multiple data-centers.
