Apache Pulsar is touted as a highly scalable, low-latency messaging platform running on commodity hardware. Besides Yahoo (NASDAQ: AABA), current enterprise users include Zhaopin Ltd., the Chinese online recruitment service. Zhaopin said Apache Pulsar addresses “the shortcomings of existing messaging systems, such as message durability, low latency.”
Other early enterprise users said they are using the messaging system as a bridge between public and private clouds as they roll out hybrid cloud strategies. Other early uses include stream processing and analysis of industrial Internet of Things sensor data. Most emerging use cases seek to move beyond slow batch processing, Pulsar supporters said.
Now that it’s a top-level Apache project, it’ll be interesting to see if it eats away at Kafka’s market share.
