Kafka provides an extremely high throughput distributed publish/subscribe
messaging system. Additionally, it supports relatively long term persistence
of messages to support a wide variety of consumers, partitioning of the
message stream across servers and consumers, and functionality for loading
data into Apache Hadoop for offline, batch processing.
Three most important issues to address in the move towards graduation:
None.
Previously, there was some concern about the diversity of the project
that we believe has been addressed:
- The project now has active committers from four companies
- and continues to receive patches from other contributors from various
institutions.
We are considering whether to pursue graduation immediately or focus
exclusively on the development of 0.8.
Any issues that the Incubator PMC or ASF Board might wish/need to be aware of:
None.
How has the community developed since the last report:
- The mailing list continues to be very active with bug reports, patch
submissions, feature requests and use cases.
[(Apr,May,Jun): kafka-users (151, 261, 251); kafka-dev (142, 195, 380)].
- Added two new committers.
- Conducted the first Kafka user group meeting with over 50 attendees
(archived video link available here: https://cwiki.apache.org/confluence/display/KAFKA/Kafka+papers+and+presentations).
This was a very successful event that gave users and contributors an
opportunity to meet and discuss Kafka usage at various companies, ongoing
development efforts, feature requests, etc.
- Received and reviewed several major patches (including contributions from
non-committers).
How has the project developed since the last report:
- Intra-cluster replication (KAFKA-50)
- Considerable progress has been made on the design and implementation of
this much-anticipated feature.
- Regular status updates are being sent out on the kafka-dev mailing list.
- Another significant project that is under discussion and development is
the consumer redesign (KAFKA-364) and consumer coordinator implementation
(KAFKA-264).
- Released Kafka 0.7.1 in June. This is the second Kafka release since its
introduction to Apache incubator

(introduced to Apache incubator on Jul 4, 2011) Kafka provides an extremely high throughput distributed publish/subscribe messaging system. Additionally, it supports relatively long term persistence of messages to support a wide variety of consumers, partitioning of the message stream across servers and consumers, and functionality for loading data into Apache Hadoop for offline, batch processing. A list of the most important issues to address in the move towards graduation - Invite diverse new active committers Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware of? - None How has the community developed since the last report? - Added a new committer. Continued contribution to source code in fixes and features and continued activity on the mailing lists. How has the project developed since the last report? - Work was begun on 0.8 release which includes our replication feature and also requires a breaking change for existing consumers/producer to the wiring protocol.

Additionally, it supports relatively long term persistence of messages to support a wide variety of consumers, partitioning of the message stream across servers and consumers, and functionality for loading data into Apache Hadoop for offline, batch processing. A list of the most important issues to address in the move towards graduation 1. Invite diverse new active committers Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware of? We incurred significant overhead during our first release; see http://apache.markmail.org/message/rsxjgrrufc6khlqy?q=list:org%2Eapache%2Eincubator%2Egeneral+from:%22junrao%22 for reference. Firstly, there is no good example to follow for a new podling. Secondly, the licensing rules are complex and the documentation is not enough for a new podling to understand. This gets more complicated since different IPMC members have different views and apply those rules slightly differently. This delays releases and causes overhead to the team. We hope that some of these things can be addressed to make the process easier to other projects. How has the community developed since the last report? Activities in the mailing list increased 4x since the last report. Several patches from non-committers have been submitted, reviewed and committed. How has the project developed since the last report? We have successfully completed the first release of Kafka after joining the incubator. This releases adds the end-to-end compression feature and mirroring support in Kafka. In addition to this, it also fixes more than 40 issues.

Invite diverse new active committers Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware of? Not at this time. How has the community developed since the last report? Mailing list traffic for July-August-September[12th] (user: 40, 65, 19; dev: 116, 371, 63) both show healthy growth trends. Qualitatively the -dev discussion has trended away from topics like "how should we configure Jira?" to "What's the best way to deal with multiple language bindings?". Several patches were submitted by first time contributors. How has the project developed since the last report? The general theme over the past month has been polish: fixing bugs, better unit tests, getting log levels right, build system cleanup etc.

A list of the three most important issues to address in the move towards graduation 1. Package, document and release at least one Apache Incubator release. 2. Develop a strong community with organizational diversity. Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware of? No, not at this time. How has the community developed since the last report? Just get started. The mailing list is pretty active, including people other than the initial committers. How has the project developed since the last report? * Moved everything (svn, website, mailing list, jira, wiki) in Kafka to Apache. CCLA from LinkedIn filed with Apache. * The end-to-end compression feature is almost complete. * Received various patches from 3 different companies, including dynamic topic discovering for cross-cluster mirroing, mx4j support, .net client, etc.
