Sorry for sending out at very last minute (deadline is today). Please take
a look.
I have added a paragraph regarding the branding discussion that happen in
early June (as discussed with Taylor then) since the previous draft was
already out at that point.
-------
Pulsar
Pulsar is a highly scalable, low latency messaging platform running on
commodity hardware. It provides simple pub-sub semantics over topics,
guaranteed at-least-once delivery of messages, automatic cursor management
for
subscribers, and cross-datacenter replication.
Pulsar has been incubating since 2017-06-01.
Most important issues to address in the move towards graduation:
None
Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?
Earlier in June there have been few discussions on the private list
regarding communications regarding Pulsar that were not coming from
PPMC or that were not respecting the ASF policies. Clarifications
followed between PPMC members, mentors and interested parties to
ensure the mistakes were made in good faith and, in particular, to
make sure everyone was fully has full understanding of ASF
policies. There was no other branding related issue after the first
occourence.
How has the community developed since the last report?
The community added 8 new contributors that submitted pull-requests
which were merged into master.
The number of users approaching the team on the Slack channel has
kept steadily increasing since the last report. Many users have
actively deployed. Pulsar for evaluation and production use cases.
Different meetups were organized by project members and hosted by
Yahoo in Sunnyvale and Yahoo Japan in Tokyo. We have presented
Pulsar's introductions, updates on the state of the projects,
deep-dives and hands-on tutorial, including recorded podcasts.
One talk on Pulsar was presented at one at OSCon in July and there
are several scheduled talks: 2 at ApacheCon in September, and 2
others at Strata New York in September.
Since the last report the number of weekly-active-users on the Slack
channel has increased from 53 to 88.
How has the project developed since the last report?
28 authors have pushed 494 commits to master in the last 3 months.
The project has made the its seventh release since joining the
Apache Incubator (2.1.0-incubating on Aug 2nd).
This release introduced these new features:
* Pulsar IO: A connector framework for moving data in and out of
Apache Pulsar leveraging Pulsar Functions runtime.
* A number of builtin connectors: (Aerospike, Cassandra, Kafka,
Kinesis, RabbitMQ, Twitter)
* Tiered Storage: An extension in Pulsar segment store to offload
older segments into long term storage (e.g. HDFS, S3). S3 support
is supported in 2.1 release.
* Stateful function: Pulsar Functions is able to use State API for
storing state within Pulsar.
* Pulsar Go Client
* Avro and Protobuf Schema support
Community is actively working on a bug-fix release
(2.1.1-incubating) and on the next milestone, 2.2 release for which
the biggest feature will be support for SQL within Pulsar.
Since June, 5 new PIPs (Pulsar Improvement Proposals) for
major feature/changes, have been submitted to the wiki and
discussed in the mailing list.
PIP 23: Message Tracing By Interceptors
PIP 22: Pulsar Dead Letter Topic
PIP 21: Pulsar Edge Component
PIP 20: Mechanism to revoke TLS authentication
PIP 19: Pulsar SQL
How would you assess the podling's maturity?
