Import statements for Kudu classes must -be modified in order to compile against 0.10.0. Wire compatibility is maintained.</p> -</li> -<li> -<p><a href="https://gerrit.cloudera.org/#/c/3055/";>Gerrit #3055</a> The Java client’s -synchronous API methods now throw <code>KuduException</code> instead of <code>Exception</code>. -Existing code that catches <code>Exception</code> should still compile, but introspection of an -exception’s message may be impacted. This change was made to allow thrown exceptions to be -queried more easily using <code>KuduException.getStatus</code> and calling one of <code>Status’s methods. -For example, an operation that tries to delete a table that doesn’t exist would return a -`Status</code> that returns true when queried on <code>isNotFound()</code>.</p> -</li> -<li> -<p>The Java client’s <code>KuduTable.getTabletsLocations</code> set of methods is now -deprecated. Additionally, they now take an exclusive end partition key instead -of an inclusive key. Applications are encouraged to use the scan tokens API -instead of these methods in the future.</p> -</li> -<li> -<p>The C++ API for specifying split points on range-partitioned tables has been improved -to make it easier for callers to properly manage the ownership of the provided rows.</p> -<div class="paragraph"> -<p>The <code>TableCreator::split_rows</code> API took a <code>vector<const KuduPartialRow*></code>, which - made it very difficult for the calling application to do proper error handling with - cleanup when setting the fields of the <code>KuduPartialRow</code>. This API has been now been - deprecated and replaced by a new method <code>TableCreator::add_range_split</code> which allows - easier use of smart pointers for safe memory management.</p> -</div> -</li> -<li> -<p>The Java client’s internal buffering has been reworked. Previously, the number of -buffered write operations was constrained on a per-tablet-server basis. Now, the configured -maximum buffer size constrains the total number of buffered operations across all -tablet servers in the cluster. This provides a more consistent bound on the memory -usage of the client regardless of the size of the cluster to which it is writing.</p> -<div class="paragraph"> -<p>This change can negatively affect the write performance of Java clients which rely on - buffered writes. Consider using the <code>setMutationBufferSpace</code> API to increase a - session’s maximum buffer size if write performance seems to be degraded after upgrading - to Kudu 0.10.0.</p> -</div> -</li> -<li> -<p>The "remote bootstrap" process used to copy a tablet replica from one host to -another has been renamed to "Tablet Copy". This resulted in the renaming of -several RPC metrics. Any users previously explicitly fetching or monitoring metrics -related to Remote Bootstrap should update their scripts to reflect the new names.</p> -</li> -<li> -<p>The SparkSQL datasource for Kudu no longer supports mode <code>Overwrite</code>. Users should -use the new <code>KuduContext.upsertRows</code> method instead. Additionally, inserts using the -datasource are now upserts by default. The older behavior can be restored by setting -the <code>operation</code> parameter to <code>insert</code>.</p> -</li> -</ul> -</div> -</div> -<div class="sect2"> -<h3 id="rn_0.10.0_new_features"><a class="link" href="#rn_0.10.0_new_features">New features</a></h3> -<div class="ulist"> -<ul> -<li> -<p>Users may now manually manage the partitioning of a range-partitioned table. -When a table is created, the user may specify a set of range partitions that -do not cover the entire available key space.

Previously, the session’s buffer size was set per tablet, meaning that a buffer -size of 1,000 for 10 tablets being written to allowed for 10,000 operations to be buffered at the -same time. With this change, all the tablets share one buffer, so users might need to set a -bigger buffer size in order to reach the same level of performance as before.</p> -</li> -<li> -<p><a href="https://gerrit.cloudera.org/#/c/3674/";>Gerrit #3674</a> Added LESS and GREATER options for -column predicates.</p> -</li> -<li> -<p><a href="https://issues.apache.org/jira/browse/KUDU-1444";>KUDU-1444</a> added support for passing -back basic per-scan metrics (e.g cache hit rate) from the server to the C++ client. See the -<code>KuduScanner::GetResourceMetrics()</code> API for detailed usage. This feature will be supported -in the Java client API in a future release.</p> -</li> -<li> -<p><a href="https://issues.apache.org/jira/browse/KUDU-1446";>KUDU-1446</a> improved the order in -which the tablet server evaluates predicates, so that predicates on smaller columns -are evaluated first.
