It can be downloaded
The major new featurs of this release are:
- Major scalability improvements. Should now support upto 990 connections
to each daemon, thousands of groups, upto 128 daemons per configuration,
and double the throughput for small messages.
- A new, more flexible and readable configuration file format. The
configuration file is now called 'spread.conf' and has a simplified
format that also allows runtime configuration of the log format, which
messages to log, and a flag to disable certain dangerous monitor commands.
All known bugs are also fixed with this version. This includes a bug with
the new NO_DROP semantics in version 3.12 and some membership crashes that
occur under high load. Behind the scenes, this version consolidates some
of the research done in the Center for Networking and Distributed Systems
lab (http://www.cnds.jhu.edu) at Johns Hopkins University over the
last few years into the public distribution.
The Non-commercial license for Spread has been updated to version 1.2. The
changes include a clarification about Spread versions, a small addition to
the attribution requirement and a capitalization of the word SPREAD.
Currently two freely-available commercial use licenses are available for
Spread. One allows the use of Spread for distributed logging of Apache web
server logs, and the other allows the use of Spread for distributed SSL
session caching with Apache-SSL. For more details please see
Other commercial licenses or other licensing arrangements are available.
