| |
| <p>The <a href="">Apache Calcite PMC</a> |
| is pleased to announce |
| <a href="/docs/history.html#v1-12-0">Apache Calcite release 1.12.0</a>.</p> |
| |
| <p>In 2½ months, |
| <a href="/docs/history.html#v1-12-0">29 contributors have resolved 95 issues</a>. |
| Here are some of the highlights.</p> |
| |
| <p>Calcite now supports JDK 9 and Guava 21.0. (It continues to run on |
| JDK 7 and 8, and on versions of Guava as early as 14.0.1. The default |
| version of Guava remains 19.0, due to the Cassandra adapter’s |
| dependencies, and the fact that Guava 21.0 requires JDK 8 or later.)</p> |
| |
| <p>There are two new adapters:</p> |
| |
| <ul> |
| <li>The <a href="https://issues.apache.org/jira/browse/CALCITE-884">File adapter</a> |
| can read files of various formats (such as CSV, JSON, zipped files, |
| and HTML) over various protocols (including file and HTTP). If |
| reading HTML files, it can extract data from nested <code class="highlighter-rouge"><TABLE></code> |
| elements.</li> |
| <li>The <a href="https://issues.apache.org/jira/browse/CALCITE-1598">Pig adapter</a> |
| provides a SQL interface to <a href="http://pig.apache.org/">Apache Pig</a>.</li> |
| </ul> |
| |
| <p>And there are continuing improvements in performance and stability of |
| the Druid adapter. (The Druid project now |
| <a href="https://github.com/druid-io/druid/pull/3682">embeds Calcite to provide SQL support</a>, |
| and there has been cross-fertilization between the projects.)</p> |
| |
| <p>To err is human, as the saying goes. If you mis-type the name of a |
| schema, table or column in a SQL statement, Calcite now |
| <a href="https://issues.apache.org/jira/browse/CALCITE-1549">helps you correct it</a>. |
| The error message indicates whether it was whether it was the schema, |
| table or column that was not found; if the mistake was just due to an |
| upper- or lower-case letter, it suggests the correct name.</p> |
| |
| <p>New SQL syntax and functions:</p> |
| |
| <ul> |
| <li><code class="highlighter-rouge">HOP</code>, <code class="highlighter-rouge">TUMBLE</code> and <code class="highlighter-rouge">SESSION</code> functions in the <code class="highlighter-rouge">GROUP BY</code> clause |
| allow you to aggregate over window types (especially useful for |
| streaming queries);</li> |
| <li>Experimental support for the <code class="highlighter-rouge">MATCH_RECOGNIZE</code> clause for |
| Complex-Event Processing (CEP);</li> |
| <li>New <code class="highlighter-rouge">YEAR</code>, <code class="highlighter-rouge">MONTH</code>, <code class="highlighter-rouge">WEEK</code>, <code class="highlighter-rouge">DAYOFYEAR</code>, <code class="highlighter-rouge">DAYOFMONTH</code>, <code class="highlighter-rouge">DAYOFWEEK</code>, |
| <code class="highlighter-rouge">HOUR</code>, <code class="highlighter-rouge">MINUTE</code>, <code class="highlighter-rouge">SECOND</code>, <code class="highlighter-rouge">DATABASE</code>, <code class="highlighter-rouge">IFNULL</code>, and <code class="highlighter-rouge">USER</code> |
| functions to comply with the ODBC/JDBC standard. Also, <code class="highlighter-rouge">EXTRACT</code> now |
| allows the corresponding time-unit arguments.</li> |
| </ul> |
