+
+<p>The release notes below are not exhaustive and only expose selected
highlights of the release. Many other bug fixes
+and improvements have been made: we refer you to the <a
href="https://github.com/apache/arrow-datafusion/blob/5.0.0/ballista/CHANGELOG.md";>complete
changelog</a>.</p>
+
+<h1 id="performance-and-scalability">Performance and Scalability</h1>
+
+<p>Ballista is now capable of running complex SQL queries at scale and
supports scalable distributed joins. We have been
+benchmarking using individual queries from the TPC-H benchmark at scale
factors up to 1000 (1 TB). When running against
+CSV files, performance is generally very close to DataFusion, and
significantly faster in some cases due to the fact
+that the scheduler limits the number of concurrent tasks that run at any given
time. Performance against large Parquet
+datasets is currently non ideal due to some issues (<a
href="https://github.com/apache/arrow-datafusion/issues/867";>#867</a>,
+<a href="https://github.com/apache/arrow-datafusion/issues/868";>#868</a>) that
we hope to resolve for the next release.</p>
+
+<h1 id="new-features">New Features</h1>
+
+<p>The main new features in this release are:</p>
+
+<ul>
+ <li>Ballista queries can now be executed by calling DataFrame.collect()</li>
+ <li>The shuffle mechanism has been re-implemented</li>
+ <li>Distributed hash-partitioned joins are now supported</li>
+ <li>Keda autoscaling is supported</li>
+</ul>
+
+<p>To get started with Ballista, refer to the <a
href="https://docs.rs/ballista/0.5.0/ballista/";>crate documentation</a>.</p>
+
+<p>Now that the basic functionality is in place, the focus for the next
release will be to improve the performance and
+scalability as well as improving the documentation.</p>
+
+<h1 id="how-to-get-involved">How to Get Involved</h1>
+
+<p>If you are interested in contributing to Ballista, we would love to have
you! You
+can help by trying out Ballista on some of your own data and projects and
filing bug reports and helping to
+improve the documentation, or contribute to the documentation, tests or code.

changelog</a>.</p>
+
+<h1 id="performance-and-scalability">Performance and
Scalability</h1>
+
+<p>Ballista is now capable of running complex SQL queries at scale and
supports scalable distributed joins. We have been
+benchmarking using individual queries from the TPC-H benchmark at scale
factors up to 1000 (1 TB). When running against
+CSV files, performance is generally very close to DataFusion, and
significantly faster in some cases due to the fact
+that the scheduler limits the number of concurrent tasks that run at any given
time. Performance against large Parquet
+datasets is currently non ideal due to some issues (<a
href="https://github.com/apache/arrow-datafusion/issues/867">#867</a>,
+<a
href="https://github.com/apache/arrow-datafusion/issues/868">#868</a>)
that we hope to resolve for the next release.</p>
+
+<h1 id="new-features">New Features</h1>
+
+<p>The main new features in this release are:</p>
+
+<ul>
+ <li>Ballista queries can now be executed by calling
DataFrame.collect()</li>
+ <li>The shuffle mechanism has been re-implemented</li>
+ <li>Distributed hash-partitioned joins are now supported</li>
+ <li>Keda autoscaling is supported</li>
+</ul>
+
+<p>To get started with Ballista, refer to the <a
href="https://docs.rs/ballista/0.5.0/ballista/">crate
documentation</a>.</p>
+
+<p>Now that the basic functionality is in place, the focus for the next
release will be to improve the performance and
+scalability as well as improving the documentation.</p>
+
+<h1 id="how-to-get-involved">How to Get Involved</h1>
+
+<p>If you are interested in contributing to Ballista, we would love to
have you! You
+can help by trying out Ballista on some of your own data and projects and
filing bug reports and helping to
+improve the documentation, or contribute to the documentation, tests or code.

-<p>The release notes below are not exhaustive and only expose selected
highlights
-of the release. Many other bugfixes and improvements have been made: we refer
-you to the <a href="/release/2.0.0.html">complete
changelog</a>.</p>
-
-<h2 id="community">Community</h2>
-
-<p>Since the 1.0.0 release, <a
href="https://github.com/jorgecarleitao">Jorge Leitão</a>
has been added as a committer. Thank
-you for your contributions!</p>
-
-<h2 id="columnar-format">Columnar Format</h2>
-
-<p>As this is the first major release since 1.0.0, we remind everyone
that we have
-moved to a “split” versioning system where the Library version (which is now
-2.0.0) will now evolve separate from the Format version (which is still
-1.0.0). Major releases of the libraries may contain non-backward-compatible API
-changes, but they will not contain any incompatible format changes. See the
-<a
href="http://arrow.apache.org/docs/format/Versioning.html">Versioning
and Stability</a> page in the documentation for more.</p>
-
-<p>The columnar format metadata has been updated to permit 256-bit
decimal values
-in addition to 128-bit decimals. This change is backward and forward
-compatible.</p>
-
-<h2 id="arrow-flight-rpc-notes">Arrow Flight RPC
notes</h2>
-
-<p>For Arrow Flight, 2.0.0 mostly brings bugfixes. In Java, some memory
leaks in
-<code class="language-plaintext
highlighter-rouge">FlightStream</code> and <code
class="language-plaintext highlighter-rouge">DoPut</code>
have been addressed. In C++ and Python, a deadlock
-has been fixed in an edge case. Additionally, when supported by gRPC, TLS
-verification can be disabled.</p>
-
-<h2 id="c-notes">C++ notes</h2>
-
-<p>Parquet reading now fully supports round trip of arbitrarily nested
data,
-including extension types with a nested storage type. In the process, several
-bugs in writing nested data and FixedSizeList were fixed. If writing data with
-these type we recommend upgrading to this release and validating old data as
-there is potential data loss.</p>
-
-<p>Datasets can now be written with partitions, including these
features:</p>
-
-<ul>
- <li>Writing to Parquet, including control over accumulation of
statistics for
-individual columns.</li>
- <li>Writing to IPC/Feather, including body buffer
compression.</li>
- <li>Basenames of written files can be specified with a string
template, allowing
-non-colliding writes into the same partitioned dataset.</li>
-</ul>
-
-<p>Other notable features in the release include</p>
-
-<ul>
- <li>Compute kernels for standard deviation, variance, and
mode</li>
- <li>Improvements to S3 support, including automatic region
detection</li>
- <li>CSV reading now parses Date type and creating Dictionary
types</li>
-</ul>
-
-<h2 id="c-notes-1">C# notes</h2>
-
-<p>The .NET package has added a number of new features this
release.</p>
-
-<p>Full support for <code class="language-plaintext
highlighter-rouge">Struct</code> types.</p>
-
-<p>Synchronous write APIs for <code class="language-plaintext
highlighter-rouge">ArrowStreamWriter</code> and <code
class="language-plaintext
highlighter-rouge">ArrowFileWriter</code>. These are
-complimentary to the existing async write APIs, and can be used in situations
-where the async APIs can’t be used.</p>
-
-<p>The ability to use <code class="language-plaintext
highlighter-rouge">DateTime</code> instances with <code
class="language-plaintext
highlighter-rouge">Date32Array</code> and <code
class="language-plaintext
highlighter-rouge">Date64Array</code>.</p>
-
-<h2 id="java-notes">Java notes</h2>
-
-<p>The Java package has supported a number of new features. Users can
validate
-vectors in a wider range of aspects, if they are willing to take more time. In
-dictionary encoding, dictionary indices can be expressed as unsigned integers.
-A framework for data compression has been setup for IPC.</p>
-
-<p>The calculation for vector capacity has been simplified, so users
should
-experience notable performance improvements for various ‘setSafe’
methods.</p>
-
-<p>Bugs for JDBC adapters, sort algorithms, and ComplexCopier have been
resolved
-to make them more usable.</p>
-
-<h2 id="javascript-notes">JavaScript notes</h2>
-
-<p>Upgrades Arrow’s build to use TypeScript 3.9, fixing generated
<code class="language-plaintext
highlighter-rouge">.d.ts</code> typings.</p>
-
-<h2 id="python-notes">Python notes</h2>
-
-<p>Parquet reading now supports round trip of arbitrarily nested data.
Several bug
-fixes for writing nested data and FixedSizeList. If writing data with these
-type we recommend validating old data (there is potential some data loss) and
-upgrade to 2.0.</p>
-
-<p>Extension types with a nested storage type now round trip through
Parquet.</p>
-
-<p>The <code class="language-plaintext
highlighter-rouge">pyarrow.filesystem</code> submodule is
deprecated in favor of new filesystem
-implementations in <code class="language-plaintext
highlighter-rouge">pyarrow.fs</code>.</p>
-
-<p>The custom serialization functionality (<code
class="language-plaintext
highlighter-rouge">pyarrow.serialize()</code>,
-<code class="language-plaintext
highlighter-rouge">pyarrow.deserialize()</code>, etc) is
deprecated. Those functions provided a
-Python-specific (not cross-language) serialization format which were not
-compatible with the standardized Arrow (IPC) serialization format. For
-arbitrary objects, you can use the standard library <code
class="language-plaintext highlighter-rouge">pickle</code>
functionality
-instead. For pyarrow objects, you can use the IPC serialization format through
-the <code class="language-plaintext
highlighter-rouge">pyarrow.ipc</code> module, as explained
above.</p>
-
-<p>The <code class="language-plaintext
highlighter-rouge">pyarrow.compute</code> module now has a
complete coverage of the available C++
-compute kernels in the python API. Several new kernels have been
added.</p>
-
-<p>The <code class="language-plaintext
highlighter-rouge">pyarrow.dataset</code> module was further
improved. In addition to reading, it
-is now also possible to write partitioned datasets (with <code
class="language-plaintext
highlighter-rouge">write_dataset()</code>).</p>
-
-<p>The Arrow &lt;-&gt; Python conversion code was refactored,
fixing several bugs and
-corner cases.</p>
-
-<p>Conversion of an array of <code class="language-plaintext
highlighter-rouge">pyarrow.MapType</code> to Pandas has been
added.</p>
-
-<p>Conversion of timezone aware datetimes to and/from pyarrow arrays
including
-pandas now round-trip preserving timezone. To use the old behavior (e.g. for
-spark) set the environment variable PYARROW_IGNORE_TIMEZONE to a truthy value
-(i.e. <code class="language-plaintext
highlighter-rouge">PYARROW_IGNORE_TIMEZONE=1</code>)</p>
-
-<h2 id="r-notes">R notes</h2>
-
-<p>Highlights of the R release include</p>
-
-<ul>
- <li>Writing multi-file datasets with partitioning to Parquet or
Feather</li>
- <li>Reading and writing directly to AWS S3, both individual files and
multi-file
-datasets</li>
- <li>Bindings for Flight which use reticulate</li>
-</ul>

--->
-
-<p>Over the last four and a half years, we’ve worked to build a
-“batteries-included” development platform for high-performance analytics
-applications in C++. As the scope of the project has grown, we have sometimes
-taken on additional library dependencies to support a wide variety of systems
-and data processing tasks.</p>
-
-<p>While these dependencies give us leverage on hard problems, in some
cases they
-have added complexity for projects that depend on Arrow. Some projects have
thus
-been concerned about depending on the Arrow C++ library, particularly if their
-use of the Arrow library’s features is limited. Indeed, in the earlier stages
of
-the Arrow project development, dependency management issues did cause problems
-for early adopters.</p>
-
-<p>We want developers to trust that they can use and depend on our
libraries, and
-that doing so doesn’t add a burden for their own project maintenance or for
-their users. Over the last year, we have undertaken a number of significant
-projects to accommodate the different ways that people want to depend on Arrow
-C++. We’ve aimed to make the build process simple by default, without requiring
-special environment setup, yet also highly configurable for those who need to
-specialize. This includes a <em>zero-dependency option</em> for
projects that wish to use
-the Arrow C++ core but take on no transitive dependencies. We’ve also worked to
-make builds faster and more compact, even as we continue to add new
-functionality.</p>
-
-<p>This post covers many of the efforts we’ve made, both in the C++
libraries and
-in the Arrow Python and R packages that depend on them. Compared to a year ago,
-the build experience is much more reliable on a wider range of platforms,
-requires fewer dependencies, and yields smaller package sizes.</p>
-
-<h2 id="minimal-default-build-options">Minimal default build
options</h2>
-
-<p>One rough edge for people using Arrow as a dependency was that many
optional
-project components were enabled in the build by default, thus requiring any
-extra dependencies of those optional components. Rather than expecting users to
-disable optional components one by one, we have made the default for all
-optional components to be <code class="language-plaintext
highlighter-rouge">OFF</code> so that the default configuration
is a
-dependency-free minimal core build.</p>
-
-<p>The only third-party library enabled by default is
-<a href="http://jemalloc.net/">jemalloc</a>, the
project’s recommended memory allocator
-(except on Windows, where it is also disabled). Given that Arrow applications
-often process large volumes of data, we have found additionally that using
-memory allocators provided by projects like jemalloc and
-<a
href="https://microsoft.github.io/mimalloc/">mimalloc</a>
yield significantly better
-performance over the default system allocators. Even so, this can also be
-disabled if desired.</p>
-
-<p>To demonstrate a minimal build, we have provided a
-<a
href="https://github.com/apache/arrow/blob/master/cpp/examples/minimal_build/Dockerfile">Dockerfile</a>
-which can be used to build the project requiring only CMake and a C++ compiler
-with zero dependencies. Additionally, we have included an
-<a
href="https://github.com/apache/arrow/tree/master/cpp/examples/minimal_build">example</a>
-of including Arrow as an external project dependency in another CMake
project.</p>
-
-<h2 id="flexible-dependency-configuration-in-cmake">Flexible
dependency configuration in CMake</h2>
-
-<p>As part of improving our CMake-based build system, we have made the
-configuration of build dependencies both flexible and consistent for different
-users’ needs. In some cases, developers want Arrow to build against
dependencies
-provided by an external package manager, such as apt in Debian-based Linux
-distributions. In other cases, developers may want to avoid any quirks of
system
-libraries and build all dependencies together with the Arrow build.</p>
-
-<p>For each package, the <code class="language-plaintext
highlighter-rouge">${Library}_SOURCE</code> CMake option can be
set to one of three
-values:</p>
-
-<ul>
- <li><code class="language-plaintext
highlighter-rouge">SYSTEM</code>, when the dependency is to be
provided externally (such as by a Linux distribution or Homebrew)</li>
- <li><code class="language-plaintext
highlighter-rouge">BUNDLED</code>, when you want the dependency
to be built from source while building Arrow, and then statically-linked with
the resulting libraries</li>
- <li><code class="language-plaintext
highlighter-rouge">AUTO</code>, which tries the <code
class="language-plaintext highlighter-rouge">SYSTEM</code>
approach but falls back on <code class="language-plaintext
highlighter-rouge">BUNDLED</code> if the dependency cannot be
located</li>
-</ul>
-
-<p>We additionally have provided <code class="language-plaintext
highlighter-rouge">CONDA</code> and <code
class="language-plaintext highlighter-rouge">BREW</code>
source types for the common
-scenarios when developers are using the conda or Homebrew package managers.
-These dependency sources can be configured on an individual dependency basis or
-globally using the <code class="language-plaintext
highlighter-rouge">ARROW_DEPENDENCY_SOURCE</code> CMake option.
<code class="language-plaintext
highlighter-rouge">AUTO</code> is default,
-which enables builds to be faster by using pre-built system libraries where
-possible but still succeed even if all dependencies are not available on the
-system.</p>
-
-<h2 id="reduced-external-dependencies">Reduced external
dependencies</h2>
-
-<p>Another area of focus was to audit our dependencies. We went through
and found
-places where we could drop external dependencies without losing useful
-functionality and without having to rewrite a lot or copy too much code into
our
-codebase.</p>
-
-<p>We have eliminated Boost as a dependency of the core Arrow library,
and in other
-components (Gandiva, Parquet, etc.), the use of Boost has been greatly reduced.
-In addition, when building Boost “bundled” in the Arrow build, we stripped down
-the Boost package we download to the minimum needed, cutting out 90 percent of
-the download size.</p>
-
-<p>We vendored a few small dependencies, such as the double-conversion
and
-uriparser libraries, so that they do not need to be downloaded and built
-separately.</p>
-
-<p>We also compiled the Flatbuffers and Thrift definitions (which are
needed to
-implement the Arrow and Parquet formats, respectively) and checked in the
-resulting C++ code to the Arrow repository. This means that Flatbuffers is no
-longer a build or runtime dependency of Arrow, and we only need the Thrift C++
-library, not the Thrift compiler, which has additional dependencies on flex and
-bison.</p>
-
-<h2 id="c-library-size-reductions">C++ library size
reductions</h2>
-
-<p>As the C++ codebase grows in size, so too does compilation times and
the amount
-of binary code generated by the C++ compiler. Over the last several months, we
-have begun analyzing the Arrow libraries both compile times and generated code
-sizes. This has yielded both significant size reductions (more than 30 percent
-code size reduction since 0.17.0). We have also restructured header files to
-avoid including unneeded header files, thus lightening the load on C++
compilers
-and improving compilation times.</p>
-
-<h2 id="python-wheels">Python wheels</h2>
-
-<p>The expectation for binary wheel packages on the Python Package Index
(PyPI) is
-that they are self-contained and have no external dependencies except on other
-Python packages. Additionally, each user of pyarrow may need different things
-from the project. Some users just want to read Parquet files and convert them
to
-pandas data frames while others want to use
-<a
href="/blog/2019/10/13/introducing-arrow-flight/">Flight</a>
for
-moving around large datasets. Thus, the “pyarrow” wheel has from the beginning
-of the project been a fairly comprehensive build including as many optional
-components as is practical for us to maintain.</p>
-
-<p>A comprehensive wheel package has some downsides: most notably for
users, it is large.
-Additionally, through a snafu relating to C++ shared libraries, for several
-releases the wheel packages would create two copies of each C++ library on
disk,
-resulting in double the amount of disk usage. This has caused problems for
-people using pyarrow in space-constrained environments like AWS
Lambda.</p>
-
-<p>In the 1.0.0 release, we have implemented some changes that have
reduced the
-size of the wheels (both in <code class="language-plaintext
highlighter-rouge">.whl</code> form and installed on disk) by
about 75 percent:</p>
-
-<ul>
- <li>Working around the problems resulting in two copies of each shared
library being created in the site-packages directory.</li>
- <li>Disabling Gandiva, which required the LLVM runtime, the largest
statically-linked dependency. Gandiva is still available to conda users
now–it’s just not included in the wheels–and we hope to package it as a
separate <code class="language-plaintext
highlighter-rouge">pyarrow-llvm</code> package in the
future.</li>
- <li>Reducing the size of the C++ shared libraries as discussed
above</li>
-</ul>
-
-<p>Now pyarrow is about the size of NumPy and thus much easier for
Python projects
-to take on as a hard dependency without worrying about large on-disk
size.</p>
-
-<p>Looking ahead, we have discussed <a
href="https://issues.apache.org/jira/browse/ARROW-8518">strategies</a>
-for breaking up pyarrow into multiple wheel packages, sort of a “hub and spoke”
-model where some optional pieces are installed as separate wheels so people
only
-needing some “core” functionality only have to install a small package. This
-would be a significant project, though, so for now we’ve focused on
improvements
-to the comprehensive wheel package.</p>
-
-<h2 id="r-packaging">R packaging</h2>
-
-<p>Packaging Arrow for R involves similar challenges to Python wheels,
though the
-technical details are unique. Like how <code class="language-plaintext
highlighter-rouge">pip install pyarrow</code> should just work
-everywhere, so should <code class="language-plaintext
highlighter-rouge">install.packages("arrow")</code> in
R, and we have invested
-significant effort to get there. Because the R package depends on a C++ library
-in active development, this is not trivial, particularly for all of the
-combinations of C++ compilers and standard libraries on Linux.</p>
-
-<p>In the initial CRAN release last year, version 0.14.1, only Windows
and macOS
-binary packages worked out of the box. For Linux, you had to install the C++
-library separately, before installing the R package. While Python wheels
contain
-binary libraries even on Linux, CRAN only hosts source packages that must be
-compiled on the user’s machine at install time. This led to an experience that
-was less than ideal for Linux users.</p>
-
-<p>Starting in version 0.16, a source package installation on Linux
handles its C++
-dependencies automatically. By default, the package executes a <a
href="https://github.com/apache/arrow/blob/master/r/inst/build_arrow_static.sh">bundled
-script</a>
-that downloads and builds the Arrow C++ library with no system dependencies
-beyond what R requires. On many common Linux distributions and versions, this
-can be sped up by
-<a href="/docs/r/articles/install.html">setting an environment
variable</a>
-to download a prebuilt static C++ library for inclusion in the
package.</p>
-
-<p>To accompany these improvements and to ensure that they succeeded on
a wide
-range of platforms, we added
-<a
href="https://github.com/apache/arrow/blob/bebcc5db3cc2890a9c53ebd53bc60863ae5ebb49/dev/tasks/tasks.yml#L1704-L1785">extensive</a>
-<a
href="https://github.com/ursa-labs/arrow-r-nightly/blob/master/.github/workflows/test-binary.yml">nightly
builds</a>
-to our continuous integration system. These are also easily extensible–all we
-need is a Docker image containing R, and we can plug new environments into our
-regular nightly testing.</p>
-
-<p>Since then, we’ve continued to improve the installation experience
and look for
-ways to reduce build time and package size. The C++ library improvements
-discussed above help the R package since most installations of the R package
-either build or otherwise include the C++ library. Within the R package itself,
-we’ve looked for ways to include just what is needed and nothing more. These
-efforts have resulted in smaller downloads and installed package sizes. From
-0.17.1 to 1.0.0, installed library sizes for macOS and Windows CRAN binaries
are
-down 10 percent, and the prebuilt static C++ libraries for Linux are 33 percent
-smaller compared to 0.16.0, despite the addition of many new
features.</p>

-
-<p>Finally, we have observed that some projects may wish to produce or
consume a
-subset of the Arrow format and do not want to take on any additional code
-dependencies. There are also scenarios where two libraries need to share
-in-memory Arrow data structures but are unable to depend on a common Arrow
-library such as the reference C++ implementation. To address these use cases,
we
-designed the <a href="/docs/format/CDataInterface.html">C
Interface</a>
-to provide a lightweight way to exchange Arrow data at the C level without any
-memory copying.</p>
-
-<p>When using the C interface, a developer populates simple C data
structures that
-contain the schema (data type) information about an Arrow data structure and
the
-addresses of the pieces of memory that constitute the data. This permits
-libraries to be plugged together easily in-memory without any shared code
-(except the C interface structure definitions). Most programming languages have
-the ability to manipulate C structures and so this interface can even be used
-without having to write or compile C code. We have used the C interface to
-<a href="/docs/r/articles/python.html">transfer data
structures between Python and R</a>
-in-memory using <code class="language-plaintext
highlighter-rouge">reticulate</code>.</p>
-
-<p>One exciting use case for the Arrow C interface is to add Arrow
import and
-export to database driver libraries which often contain a C API.</p>

-<h2 id="looking-ahead">Looking ahead</h2>

-<p>As the project grows, we will continue working to make the build
process as
-fast and reliable as possible. If you see ways we can improve it further, or if
-you run into trouble, please bring it up on our
