     <h1 class="title">Apache Accumulo 1.7.0 Release Notes</h1>
     <p>Apache Accumulo 1.7.0 is a release that needs to be described</p>
+<h1 id="draft-draft-draft-draft-draft-draft">DRAFT DRAFT DRAFT DRAFT DRAFT DRAFT</h1>
+<h3 id="user-initiated-compaction-strategies">User Initiated Compaction Strategies</h3>
+<p>Per table compaction strategies were added in 1.6.0.  In 1.7.0 the ability to
+specify a compaction strategy for a user initiated compaction was added in
+<a href="">ACCUMULO-1798</a>.
  This allows surgical compactions on a subset 
+of tablets files.  Previously a user initiated compaction would compact all 
+files in a tablet.</p>
+<p>In the Java API, this new feature can be accessed in the following way :</p>

+<p>In <a href="">ACCUMULO-3134</a>
the shell's compact command was modified to 
+enable selecting which files to compact based on size, name, and path.  Options 
+were also added to the shell's compaction command to allow setting RFile options
+for the compaction output.  Setting the output options could be useful for 
+testing.  For example, one tablet to be compacted using snappy.</p>
+<p>The following is an example shell command that compacts all files less than
+10MB, if the tablet has at least two files that meet this criteria.  If a
+tablet had a 100MB, 50MB, 7MB, and 5MB file then the 7MB and 5MB files would be
+compacted.  If a tablet had a 100MB and 5MB file, then nothing would be done
+because there are not at least two files meeting the selection criteria.</p>
