The documentation for both users and developers +continues to receive improvements.</p> + +<p>Authentication is a major theme of this release, providing multiple layers of +additional authentication mechanisms over previous versions. In these earlier +versions, the only authentication provided by Avatica was achieved via the JDBC URLâs +standard user and password options. These have always been passed directly into +the backend databaseâs authentication system, but not all databases provide username +and password based authentication systems. <a href="https://issues.apache.org/jira/browse/CALCITE-1173">CALCITE-1173</a> +adds Avatica-level authentication over <a href="https://en.wikipedia.org/wiki/Basic_access_authentication">HTTP Basic</a> +and <a href="https://en.wikipedia.org/wiki/Digest_access_authentication">HTTP Digest</a> +authentication mechanisms. These are provided specifically for the case when +Avatica is used with a database that <em>does not already</em> provide its own authentication +implementation.</p> + +<p>Some systems rely on <a href="http://web.mit.edu/kerberos/">Kerberos</a> for strong, centrally- +managed authentication. <a href="https://issues.apache.org/jira/browse/CALCITE-1159">CALCITE-1159</a> +introduces Kerberos-based authentication for clients via <a href="https://en.wikipedia.org/wiki/SPNEGO">SPNEGO</a>. +The Avatica server can be configured to only allow clients with a valid Kerberos ticket, +optionally, also passing this information to the backend database to implement +basic âimpersonationâ (where the Avatica server issues requests on behalf of the end user).</p> + +<p>Building on top of the work done in Avatica-1.7.0 in <a href="https://issues.apache.org/jira/browse/CALCITE-1091">CALCITE-1091</a>, +this release also contains <a href="https://issues.apache.org/jira/browse/CALCITE-1128">CALCITE-1128</a> which +implements the batch-oriented JDBC APIs on <code class="highlighter-rouge">Statement</code>. Through careful inspection, it +was observed that the overall performance of Avatica clients in 100% write workloads was +dominated by the cost of the HTTP calls. By leveraging the <code class="highlighter-rouge">Statement#addBatch()</code> +and <code class="highlighter-rouge">Statement#executeBatch()</code> API calls, clients can efficiently batch multiple updates +in a single HTTP call. In testing this over the previous single HTTP call per update with +<a href="https://phoenix.apache.org">Apache Phoenix</a>, it was observed that performance increased by +two to three times, bringing Avaticaâs performance on par with the Phoenix ânativeâ driver.</p> + +<p>Returning back to compatibility, a new component appears in this release which is designed to +test versions of Avatica against each other. <a href="https://issues.apache.org/jira/browse/CALCITE-1190">CALCITE-1190</a> +introduces a âTechnology Compatibility Kitâ (TCK) which automates the testing of one version +of Avatica against other versions. To further ease this testing, a runnable JAR to launch +an HSQLDB instance and an Avatica server also makes it debut with these changes. This TCK +makes it much easier to run tests of newer clients against older servers and vice versa. +Validating the backwards compatibility that is being built is extremely important to be +confident in the guarantees being provided to users.</p> + +<p>Finally, a number of bugs are also fixed in the Protocol Buffer wire API. Some of these +include <a href="https://issues.apache.org/jira/browse/CALCITE-1113">CALCITE-1113</a> and +<a href="https://issues.apache.org/jira/browse/CALCITE-1103">CALCITE-1103</a> which fix how certain +numbers are serialized, <a href="https://issues.apache.org/jira/browse/CALCITE-1243">CALITE-1243</a> +which corrects some fields in Protocol Buffer messages which were incorrectly marked +as unsigned integers instead of signed integers, and <a href="https://issues.apache.org/jira/browse/CALCITE-1209">CALCITE-1209</a> +which removes incorrect parsing of binary fields as Base64-encoded strings. All of +these issues are fixed in a backwards-compatible manner and should have no additional negative +impact on older clients (older clients will not break, but they may continue to return +incorrect data for certain numbers).</p> + +<p>For users of the Avatica driver, a new <a href="/avatica/docs/client_reference.html">client reference page</a> +is added which details the options that are available in the Avatica JDBC Driverâs URL. +The wire API documentation for Protocol Buffers continues to receive updates as the API continues to evolve.</p> + + + + <p>See the <a href="/avatica/docs/history.html#">release notes</a>; + <a href="/avatica/downloads/avatica.html#source-releases">download</a> the release.</p> + + + </div> +</article> + + + + + +<article> + <h2> + <a href="/avatica/news/2016/03/18/release-1.7.1/"> + Release 1.7.1 + </a> + </h2> + <span class="post-category"> + <span class="label"> + release + </span> + </span> + <div class="post-meta"> + <span class="post-date"> + 18 Mar 2016 + </span> + + + + <a href="http://github.com/joshelser" class="post-author"> + <img src="http://github.com/joshelser.png" + class="avatar" alt="elserj avatar" + width="24" height="24"> + elserj + </a> + </div> + <div class="post-content"> + <!-- + +--> + +<p>Apache Calciteâs PMC has just released Avatica 1.7.1, the first +release of <a href="http://calcite.apache.org/avatica/">Avatica</a> as an +independent project.
