Subject [ANNOUNCE] Apache Apex Core 3.5.0 released
Date Mon, 19 Dec 2016 23:38:40 GMT
Dear Community,

The Apache Apex community is pleased to announce release 3.5.0 of Apex Core
(the engine).

Apache Apex is an enterprise grade big data-in-motion platform that unifies
stream and batch processing. Apex was built for scalability and low-latency
processing, high availability and operability.

This release upgrades the Apache Hadoop YARN dependency from 2.2 to 2.6.
The community determined that current users run on versions equal or higher
than 2.6 and Apex can now take advantage of more recent capabilities of
YARN. The release contains a number of important bug fixes and operability
improvements.

See full release notes
<https://issues.apache.org/jira/secure/ReleaseNote.jspa?version=12335724&styleName=Text&projectId=12318823>
for
all changes in this release.

Apex provides features that similar platforms currently don’t offer, such
as fine grained, incremental recovery to only reset the portion of a
topology that is affected by a failure, support for elastic scaling based
on the ability to acquire (and release) resources as needed as well as the
ability to alter topology and operator properties on running applications.

Apex has been developed since 2012 and became ASF top level project earlier
this year, following 8 months of incubation. Apex early on brought the
combination of high throughput, low latency and fault tolerance with strong
processing guarantees to the stream data processing space and gained
maturity through important production use cases at several organizations.
See the powered by page and resources on the project web site for more
information:

The Apex engine is supplemented by Malhar, the library of pre-built
operators, including adapters that integrate with many existing
technologies as sources and destinations, like message buses, databases,
files or social media feeds.

An easy way to get started with Apex is to pick one of the examples as
starting point. They cover many common and recurring tasks, such as data
consumption from different sources, output to various sinks, partitioning
and fault tolerance:

Apex Malhar and Core (the engine) are separate repositories and releases.
We expect more frequent releases of Malhar to roll out new connectors and
other operators based on a stable engine API. This release 3.6.0 works on
existing Apex Core 3.4.0. Users only need to upgrade the Maven dependency
in their project.
