Apache Kafka is a distributed event streaming platform for efficiently storing and processing a large number of records in real time. Development =========== We released the 2.7.0, which includes the following key features. - Configurable TCP connection timeout and improve the initial metadata fetch - Enforce broker-wide and per-listener connection creation rate - Throttle Create Topic, Create Partition and Delete Topic Operations - Add TRACE-level end-to-end latency metrics to Streams - Add Broker-side SCRAM Config API - Support PEM format for SSL certificates and private key - Add RocksDB Memory Consumption to RocksDB Metrics - Add Sliding-Window support for Aggregations We’ve continued steady progress toward the task of replacing ZooKeeper in Kafka. We expect to have some limited functionalities in the upcoming 2.8.0 release that demonstrate much higher scalability for the metadata. Tiered Storage work continues and unlocks infinite scaling and faster rebalance times via KIP-405. The KIP proposal is getting closer for voting. Community =========== Dev mailing list had a 39% increase in traffic in the past quarter (3246 emails compared to 2333).

With the help from ASF branding committee, Kafka PMC passed a relaxed naming policy for non-java clients and connectors. Quite a few non-java clients and connectors have been using Kafka in its name. Those products form a critical eco-system for Apache Kafka since Apache Kafka doesn't provide them directly. We feel that requiring all of them to change their product name is detrimental to the Kafka community. The relaxed policy can be found at https://kafka.apache.org/trademark Releases =========== 2.7.0 was released on Dec. 21, 2020. 2.6.1 was released on Jan. 7, 2021.

Special Order 7C, Establish the Apache Kafka Project, was
approved by Unanimous Vote of the directors present.
(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.
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.

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.

A list of the most important issues to address in the move towards graduation 1. Successful podling release. 2. 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.

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 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.
