Re: [ANNOUNCE] Apache Kafka 1.0.0 Released

[Ismael Juma]

Thanks Sebb. For reference, Sebb filed KAFKA-6222 and KAFKA-6223, so let's
keep the discussion in the relevant JIRAs.

Please don't publish the dist.apache.org URL.
It is only intended as a staging host and does not have the bandwidth
for general downloads.

In future, please only use the ASF mirror system for advertising downloads.

For KEYS, sigs and hashes, use the ASF mirror source at:

https://www.apache.org/dist/kafka/...

This would also be OK for small files such as release notes, i.e. you can use:

https://www.apache.org/dist/kafka/1.0.0/RELEASE_NOTES.html

For files such as binaries and source archives, use the 3rd party
mirrors (as you have done below).

Thanks.

These are fine.

Thanks for running the release, Guozhang! Also thanks to all the
contributors who made 1.0 possible. :)

The Apache Kafka community is pleased to announce the release for Apache
Kafka 1.0.0.

This is a major release of the Kafka project, and is no mere bump of the
version number. The Apache Kafka Project Management Committee has packed a
number of valuable enhancements into the release. Let me summarize a few of
them:

** Since its introduction in version 0.10, the Streams API has become
hugely popular among Kafka users, including the likes of Pinterest,
Rabobank, Zalando, and The New York Times. In 1.0, the the API continues to
evolve at a healthy pace. To begin with, the builder API has been improved
(KIP-120). A new API has been added to expose the state of active tasks at
runtime (KIP-130). Debuggability gets easier with enhancements to the
print() and writeAsText() methods (KIP-160). And if that’s not enough,
check out KIP-138 and KIP-161 too. For more on streams, check out the
Apache Kafka Streams documentation (https://kafka.apache.org/docu
mentation/streams/ ),
including some helpful new tutorial videos.

** Operating Kafka at scale requires that the system remain observable, and
to make that easier, we’ve made a number of improvements to metrics. These
are too many to summarize without becoming tedious, but Connect metrics
have been significantly improved (KIP-196), a litany of new health check
metrics are now exposed (KIP-188), and we now have a global topic and
partition count (KIP-168). Check out KIP-164 and KIP-187 for even more.

** We now support Java 9, leading, among other things, to significantly
faster TLS and CRC32C implementations. Over-the-wire encryption will be
faster now, which will keep Kafka fast and compute costs low when
encryption is enabled.

** In keeping with the security theme, KIP-152 cleans up the error handling
on Simple Authentication Security Layer (SASL) authentication attempts.
Previously, some authentication error conditions were indistinguishable
from broker failures and were not logged in a clear way. This is cleaner
now.

** Kafka can now tolerate disk failures better. Historically, JBOD storage
configurations have not been recommended, but the architecture has
nevertheless been tempting: after all, why not rely on Kafka’s own
replication mechanism to protect against storage failure rather than using
RAID? With KIP-112, Kafka now handles disk failure more gracefully. A
single disk failure in a JBOD broker will not bring the entire broker down;
rather, the broker will continue serving any log files that remain on
functioning disks.

** Since release 0.11.0, the idempotent producer (which is the producer
used in the presence of a transaction, which of course is the producer we
use for exactly-once processing) required max.in.flight.requests.per.con
nection
to be equal to one. As anyone who has written or tested a wire protocol can
attest, this put an upper bound on throughput. Thanks to KAFKA-5949, this
can now be as large as five, relaxing the throughput constraint quite a bit.

Apache Kafka is a distributed streaming platform with four four core APIs:

** The Producer API allows an application to publish a stream records to one
or more Kafka topics.

** The Consumer API allows an application to subscribe to one or more topics
and process the stream of records produced to them.

** The Streams API allows an application to act as a stream processor,
consuming
an input stream from one or more topics and producing an output stream to
one or more output topics, effectively transforming the input streams to
output streams.

** The Connector API allows building and running reusable producers or
consumers
that connect Kafka topics to existing applications or data systems. For
example, a connector to a relational database might capture every change to
a table.three key capabilities:


With these APIs, Kafka can be used for two broad classes of application:

** Building real-time streaming data pipelines that reliably get data
between
systems or applications.

** Building real-time streaming applications that transform or react
to the streams
of data.


Apache Kafka is in use at large and small companies worldwide, including
Capital One, Goldman Sachs, ING, LinkedIn, Netflix,

This is a major release of the Kafka project, and is no mere bump of the

them:

** Since its introduction in version 0.10, the Streams API has become
hugely popular among Kafka users, including the likes of Pinterest,
Rabobank, Zalando, and The New York Times. In 1.0, the the API continues to
evolve at a healthy pace. To begin with, the builder API has been improved
(KIP-120). A new API has been added to expose the state of active tasks at

check out KIP-138 and KIP-161 too. For more on streams, check out the
Apache Kafka Streams documentation (https://kafka.apache.org/docu
mentation/streams/), including some helpful new tutorial videos.

** Operating Kafka at scale requires that the system remain observable, and
to make that easier, we’ve made a number of improvements to metrics. These
are too many to summarize without becoming tedious, but Connect metrics
have been significantly improved (KIP-196), a litany of new health check
metrics are now exposed (KIP-188), and we now have a global topic and
partition count (KIP-168). Check out KIP-164 and KIP-187 for even more.

** We now support Java 9, leading, among other things, to significantly
faster TLS and CRC32C implementations. Over-the-wire encryption will be
faster now, which will keep Kafka fast and compute costs low when
encryption is enabled.

** In keeping with the security theme, KIP-152 cleans up the error handling
on Simple Authentication Security Layer (SASL) authentication attempts.
Previously, some authentication error conditions were indistinguishable
from broker failures and were not logged in a clear way. This is cleaner
now.

** Kafka can now tolerate disk failures better. Historically, JBOD storage
configurations have not been recommended, but the architecture has
nevertheless been tempting: after all, why not rely on Kafka’s own
replication mechanism to protect against storage failure rather than using
RAID? With KIP-112, Kafka now handles disk failure more gracefully. A
single disk failure in a JBOD broker will not bring the entire broker down;
rather, the broker will continue serving any log files that remain on
functioning disks.

** Since release 0.11.0, the idempotent producer (which is the producer
used in the presence of a transaction, which of course is the producer we
use for exactly-once processing) required max.in.flight.requests.per.connection
to be equal to one. As anyone who has written or tested a wire protocol can

Apache Kafka is a distributed streaming platform with four four core APIs:

** The Producer API allows an application to publish a stream records to one
or more Kafka topics.

** The Consumer API allows an application to subscribe to one or more topics
and process the stream of records produced to them.

** The Streams API allows an application to act as a stream processor,
consuming
an input stream from one or more topics and producing an output stream to
one or more output topics, effectively transforming the input streams to
output streams.

** The Connector API allows building and running reusable producers or
consumers
that connect Kafka topics to existing applications or data systems. For
example, a connector to a relational database might capture every change to
a table.three key capabilities:


With these APIs, Kafka can be used for two broad classes of application:

** Building real-time streaming data pipelines that reliably get data between
systems or applications.

** Building real-time streaming applications that transform or react
to the streams
of data.


Apache Kafka is in use at large and small companies worldwide, including
Capital One, Goldman Sachs, ING, LinkedIn, Netflix, Pinterest,

[ANNOUNCE] Apache Kafka 1.0.0 Released

[Guozhang Wang]

The Apache Kafka community is pleased to announce the release for Apache
Kafka 1.0.0.

This is a major release of the Kafka project, and is no mere bump of the
version number. The Apache Kafka Project Management Committee has packed a
number of valuable enhancements into the release. Let me summarize a few of
them:

** Since its introduction in version 0.10, the Streams API has become
hugely popular among Kafka users, including the likes of Pinterest,
Rabobank, Zalando, and The New York Times. In 1.0, the the API continues to
evolve at a healthy pace. To begin with, the builder API has been improved
(KIP-120). A new API has been added to expose the state of active tasks at
runtime (KIP-130). Debuggability gets easier with enhancements to the
print() and writeAsText() methods (KIP-160). And if that’s not enough,
check out KIP-138 and KIP-161 too. For more on streams, check out the
Apache Kafka Streams documentation (https://kafka.apache.org/docu
mentation/streams/), including some helpful new tutorial videos.

** Operating Kafka at scale requires that the system remain observable, and
to make that easier, we’ve made a number of improvements to metrics. These
are too many to summarize without becoming tedious, but Connect metrics
have been significantly improved (KIP-196), a litany of new health check
metrics are now exposed (KIP-188), and we now have a global topic and
partition count (KIP-168). Check out KIP-164 and KIP-187 for even more.

** We now support Java 9, leading, among other things, to significantly
faster TLS and CRC32C implementations. Over-the-wire encryption will be
faster now, which will keep Kafka fast and compute costs low when
encryption is enabled.

** In keeping with the security theme, KIP-152 cleans up the error handling
on Simple Authentication Security Layer (SASL) authentication attempts.
Previously, some authentication error conditions were indistinguishable
from broker failures and were not logged in a clear way. This is cleaner
now.

** Kafka can now tolerate disk failures better. Historically, JBOD storage
configurations have not been recommended, but the architecture has
nevertheless been tempting: after all, why not rely on Kafka’s own
replication mechanism to protect against storage failure rather than using
RAID? With KIP-112, Kafka now handles disk failure more gracefully. A
single disk failure in a JBOD broker will not bring the entire broker down;
rather, the broker will continue serving any log files that remain on
functioning disks.

** Since release 0.11.0, the idempotent producer (which is the producer
used in the presence of a transaction, which of course is the producer we
use for exactly-once processing) required max.in.flight.requests.per.connection
to be equal to one. As anyone who has written or tested a wire protocol can
attest, this put an upper bound on throughput. Thanks to KAFKA-5949, this
can now be as large as five, relaxing the throughput constraint quite a bit.
