The decimal type is a numeric +data type with fixed scale and precision suitable for financial and other +arithmetic calculations where the imprecise representation and rounding +behavior of float and double make those types impractical. The decimal type +is also useful for integers larger than int64 and cases with fractional values +in a primary key. See <a href="/releases/1.7.0/docs/schema_design.html#decimal">Decimal Type</a> +for more details.</li> + <li>The strategy Kudu uses for automatically healing tablets which have lost a +replica due to server or disk failures has been improved. The new re-replication +strategy, or replica management scheme, first adds a replacement tablet replica +before evicting the failed one.</li> + <li>A new scan read mode READ_YOUR_WRITES. Users can specify READ_YOUR_WRITES when +creating a new scanner in C++, Java and Python clients. If this mode is used, +the client will perform a read such that it follows all previously known writes +and reads from this client. Reads in this mode ensure read-your-writes and +read-your-reads session guarantees, while minimizing latency caused by waiting +for outstanding write transactions to complete. Note that this is still an +experimental feature which may be stabilized in future releases.</li> + <li>The tablet server web UI scans dashboard (/scans) has been improved with several +new features, including: showing the most recently completed scans, a pseudo-SQL +scan descriptor that concisely shows the selected columns and applied predicates, +and more complete and better documented scan statistics.</li> + <li>Kudu daemons now expose a web page /stacks which dumps the current stack trace of +every thread running in the server. This information can be helpful when diagnosing +performance issues.</li> + <li>By default, each tablet replica will now stripe data blocks across 3 data directories +instead of all data directories. This decreases the likelihood that any given tablet +will be affected in the event of a single disk failure.</li> + <li>The Java client now uses a predefined prioritized list of TLS ciphers when +establishing an encrypted connection to Kudu servers. This cipher list matches the +list of ciphers preferred for server-to-server communication and ensures that the +most efficient and secure ciphers are preferred. When the Kudu client is running on +Java 8 or newer, this provides a substantial speed-up to read and write performance.</li> + <li>The performance of inserting rows containing many string or binary columns has been +improved, especially in the case of highly concurrent write workloads.</li> + <li>The Java client will now automatically attempt to re-acquire Kerberos credentials +from the ticket cache when the prior credentials are about to expire. This allows +client instances to persist longer than the expiration time of a single Kerberos +ticket so long as some other process renews the credentials in the ticket cache.</li> +</ol> + +<p>For more details, and the complete list of changes in Kudu 1.7.0, please see +the <a href="/releases/1.7.0/docs/release_notes.html">Kudu 1.7.0 release notes</a>.</p> + +<p>The Apache Kudu project only publishes source code releases.

This weekly blog post -covers ongoing development and news in the Apache Kudu project.</p> - -<!--more--> - -<h2 id="development-discussions-and-code-in-progress">Development discussions and code in progress</h2> - -<ul> - <li> - <p>Dan Burkert committed a piece of test infrastructure -called âMiniKDCâ for both Java and C++. The MiniKDC sets up a short-lived -Kerberos environment in the context of a single test case, making it -easy to build tests of security features without requiring any special -infrastructure on the part of the developer.</p> - </li> - <li> - <p>Todd Lipcon added support for Kerberos (GSSAPI) support to Kuduâs -RPC system, allowing servers to authenticate the user principal of -any inbound RPC connection. He also integrated Kuduâs C++ âMiniClusterâ -test infrastructure to allow starting a Kerberized cluster in the -context of a test.</p> - </li> - <li> - <p>Dan, Todd, and Alexey Serbin have been iterating on a more detailed -<a href="https://docs.google.com/document/d/1Yu4iuIhaERwug1vS95yWDd_WzrNRIKvvVGUb31y-_mY/edit#">design doc</a> -for authentication in Kudu. This doc outlines the various non-Kerberos -methods that Kudu will use for authentication as well as how TLS will -be used to encrypt and authenticate some types of connections.</p> - </li> - <li> - <p>Part of the above design document involves Kudu servers generating and -signing X509 certificates on the fly to use for authenticated TLS. -Alexey has been working on a large <a href="https://gerrit.cloudera.org/#/c/4799/">patch</a> -which uses OpenSSL to provide key generation and signing functionality.</p> - </li> - <li> - <p>Sailesh Mukil has been working on adding support for -<a href="https://gerrit.cloudera.org/#/c/4789/">TLS in Kuduâs RPC system</a>. The TLS -support is a critical part of the overall design for security. This patch -has gone through several rounds of review and nearing completion.</p> - </li> - <li> - <p>JD Cryans has been continuing to improve the Java client, including adding -the ability to specify that the client would like to read the âclosestâ -replica (e.g. reading from a local copy if possible). Additionally, -JD has been working on some basic <a href="https://gerrit.cloudera.org/#/c/4781/">tracing support</a> -within the Java client. This tracing aims to make timeouts easier to understand -and diagnose.</p> - </li> - <li> - <p>Jordan Birdsell committed 9 more patches to the Python client, bringing it -very close to feature parity with C++. Jordan has a few more patches in flight -which should complete this long-running effort.</p> - </li> - <li> - <p>Congrats to new contributor Haijie Hong who committed his first patch this week. -Haijie added support for <a href="https://gerrit.cloudera.org/#/c/4822/">run-length encoding 64-bit integers</a>.</p> - </li> - <li> - <p>Will Berkeley picked back up work on <a href="https://gerrit.cloudera.org/#/c/4310/">improving the capability of ALTER -TABLE</a>. His in-flight patch adds support -for changing the default value of a column as well as changing storage attributes -such as desired block size, encoding, and compression.</p> - </li> - <li> - <p>Adar Dembo has been working on a series of patches for the Block Manager, the -component of Kudu which is responsible for laying out blocks on the local -file system. His patch series consists of a number of refactors to clean up -and improve the code structure, followed by an <a href="https://gerrit.cloudera.org/#/c/4848/">improvement to reduce file system -fragmentation</a>.</p> - </li> - <li> - <p>David Alves has been working on a <a href="https://gerrit.cloudera.org/#/c/4819/">patch series</a> -which adds support for storing âREINSERTâ deltas on disk. These records are -generated if a user inserts a row, deletes it, and inserts a new row with the -same primary key. Current versions of Kudu lose track of the history of the -prior version of the row in this scenario, which prevents correct snapshot reads. -Davidâs patch series fixes this.</p> - </li> -</ul> - -<p>Want to learn more about a specific topic from this blog post?
