+ <p class="post-meta" >Jan 18, 2019 ⢠Yanghong Zhong</p>
+ </header>
+
+ <article class="post-content" >
+ <p>The Apache Kylin community is pleased to announce the release of Apache Kylin v2.6.0.</p>
+
+<p>Apache Kylin is an open source Distributed Analytics Engine designed to provide SQL interface and multi-dimensional analysis (OLAP) on Big Data supporting extremely large datasets.</p>
+
+<p>This is a major release after 2.5.0, including many enhancements. All of the changes can be found in the <a href="https://kylin.apache.org/docs/release_notes.html">release notes</a>. Here just highlight the major ones:</p>
+
+<h3 id="sdk-for-jdbc-sources">SDK for JDBC sources</h3>
+<p>Apache Kylin has already supported several data sources like Amazon Redshift, SQL Server through JDBC. <br />
+To help developers handle SQL dialect differences and easily implement a new data source through JDBC, Kylin provides a new data source SDK with APIs for:<br />
+* Synchronize metadata and data from JDBC source<br />
+* Build cube from JDBC source<br />
+* Query pushdown to JDBC source engine when cube is unmatched</p>
+
+<p>Check KYLIN-3552 for more.</p>
+
+<h3 id="memcached-as-distributed-cache">Memcached as distributed cache</h3>
+<p>In the past, query caches are not efficiently used in Kylin due to two aspects: aggressive cache expiration strategy and local cache. <br />
+Because of the aggressive cache expiration strategy, useful caches are often cleaned up unnecessarily. <br />
+Because query caches are stored in local servers, they cannot be shared between servers. <br />
+And because of the size limitation of local cache, not all useful query results can be cached.</p>
+
+<p>To deal with these shortcomings, we change the query cache expiration strategy by signature checking and introduce the memcached as Kylinâs distributed cache so that Kylin servers are able to share cache between servers. <br />
+And itâs easy to add memcached servers to scale out distributed cache. With enough memcached servers, we can cached things as much as possible. <br />
+Then we also introduce segment level query cache which can not only speed up query but also reduce the rpcs to HBase. <br />
+The related tasks are KYLIN-2895, KYLIN-2894, KYLIN-2896, KYLIN-2897, KYLIN-2898, KYLIN-2899.</p>
+
+<h3 id="forkjoinpool-for-fast-cubing">ForkJoinPool for fast cubing</h3>
+<p>In the past, fast cubing uses split threads, task threads and main thread to do the cube building, there is complex join and error handling logic.</p>
+
+<p>The new implement leverages the ForkJoinPool from JDK, the event split logic is handled in<br />
+main thread. Cuboid task and sub-tasks are handled in fork join pool, cube results are collected<br />
+async and can be write to output earlier. Check KYLIN-2932 for more.</p>
+
+<h3 id="improve-hllcounter-performance">Improve HLLCounter performance</h3>
+<p>In the past, the way to create HLLCounter and to compute harmonic mean are not efficient.</p>
+
+<p>The new implement improve the HLLCounter creation by copy register from another HLLCounter instead of merge. To compute harmonic mean in the HLLCSnapshot, it does the enhancement by <br />
+* using table to cache all 1/2^r without computing on the fly<br />
+* remove floating addition by using integer addition in the bigger loop<br />
+* remove branch, e.g. neednât checking whether registers[i] is zero or not, although this is minor improvement.</p>
+
+<p>Check KYLIN-3656 for more.</p>

+<h3 id="improve-cuboid-recommendation-algorithm">Improve Cuboid Recommendation Algorithm</h3>
+<p>In the past, to add cuboids which are not prebuilt, the cube planner turns to mandatory cuboids which are selected if its rollup row count is above some threshold. <br />
+There are two shortcomings:<br />
+* The way to estimate the rollup row count is not good<br />
+* Itâs hard to determine the threshold of rollup row count for recommending mandatory cuboids</p>
+
+<p>The new implement improves the way to estimate the row count of un-prebuilt cuboids by rollup ratio rather than exact rollup row count. <br />
+With better estimated row counts for un-prebuilt cuboids, the cost-based cube planner algorithm will decide which cuboid to be built or not and the threshold for previous mandatory cuboids is not needed. <br />
+By this improvement, we donât need the threshold for mandatory cuboids recommendation, and mandatory cuboids can only be manually set and will not be recommended. Check KYLIN-3540 for more.</p>
