Date Fri, 03 Aug 2018 18:14:31 GMT
The Apache Pulsar team is proud to announce Apache Pulsar version

This is the seventh Pulsar release after entering the Apache Incubator.

Pulsar is a highly scalable, low latency messaging streaming platform
running on
commodity hardware. It provides simple pub/sub semantics over topics,
at-least-once and effectively-once delivery of messages, automatic cursor
for subscribers, and multi-tenancy and cross-datacenter replication.
it also provides lightweight stream native processing through Pulsar

2.1.0-incubating release introduces several major features and improvements
from many contributors. These major features include:

- Pulsar IO <>: A
serverless inspired connector framework for moving data in and out of
Apache Pulsar leveraging Pulsar Functions
<>. 6
builtin connectors are included: Kafka
<>, Kinesis
<>, RabbitMQ
<>, Aerospike
<>, Cassandra
<> and Twitter
Firehose <>.

- Tiered Storage
<>: An
offloading mechanism in Pulsar segment store to offload old segments from
Apache BookKeeper into long term storage such as HDFS, S3, GCS. S3 is
currently supported in this release.

- Stateful Function
<>: Pulsar
Functions introduces a new State API
<> to store
function state back to Apache BookKeeper. It is a deep integration with
BookKeeper's table service and it will simplify developing stateful
applications using Pulsar Functions. It is available as a developer-preview
feature in Java SDK.

- Go Client
<>: A cgo
wrapper over existing c++ client.

- More Schemas are introduced, including Avro
and Protobuf

The Pulsar Team

Apache Pulsar is an effort undergoing incubation at The Apache Software
Foundation (ASF), sponsored by the Apache Incubator PMC. Incubation is
required of all newly accepted projects until a further review indicates
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
of the code, it does indicate that the project has yet to be fully endorsed
by the ASF.
