<p>Repairs can take a very long time in some environments, for large sizes of data. Use this tool to set the repairedAt status on a given set of sstables, so that repairs can be run on only un-repaired sstables if desired.</p>
<p>Note that running a repair (e.g., via nodetool repair) doesn’t set the status of this metadata. Only setting the status of this metadata via this tool does.</p>
<p>ref: <a class="reference external" href="https://issues.apache.org/jira/browse/CASSANDRA-5351">https://issues.apache.org/jira/browse/CASSANDRA-5351</a></p>
<p>Cassandra must be stopped before this tool is executed, or unexpected results will occur. Note: the script does not verify that Cassandra is stopped.</p>

<h2>Set a lot of sstables to unrepaired status<a class="headerlink" href="#set-a-lot-of-sstables-to-unrepaired-status" title="Permalink to this headline">¶</a></h2>
<p>There are many ways to do this programmatically. This way would likely include variables for the keyspace and table.</p>
<p>Example:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">find</span> <span class="o">/</span><span class="n">var</span><span class="o">/</span><span class="n">lib</span><span class="o">/</span><span class="n">cassandra</span><span class="o">/</span><span class="n">data</span><span class="o">/</span><span class="n">keyspace1</span><span class="o">/</span><span class="n">standard1</span><span class="o">-</span><span class="n">d936bd20a17c11e8bc92a55ed562cd82</span><span class="o">/*</span> <span class="o">-</span><span class="n">name</span> <span class="s2">&quot;*Data.db&quot;</span> <span class="o">-</span><span class="n">print0</span> <span class="o">|</span> <span class="n">xargs</span> <span class="o">-</span><span class="mi">0</span> <span class="o">-</span><span class="n">I</span> <span class="o">%</span> <span class="n">sstablerepairedset</span> <span class="o">--</span><span class="n">really</span><span class="o">-</span><span class="nb">set</span> <span class="o">--</span><span class="ow">is</span><span class="o">-</span><span class="n">unrepaired</span> <span class="o">%</span>

<div class="section" id="set-one-to-many-sstables-to-repaired-status">
<h2>Set one to many sstables to repaired status<a class="headerlink" href="#set-one-to-many-sstables-to-repaired-status" title="Permalink to this headline">¶</a></h2>
<p>Set the repairedAt status after a repair to mark the sstables as repaired. Again, using variables for the keyspace and table names is a good choice.</p>
<p>Example:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">nodetool</span> <span class="n">repair</span> <span class="n">keyspace1</span> <span class="n">standard1</span>
