 <p>Bulk-load the sstables found in the directory &lt;dir_path&gt; to the configured cluster. The parent directories of &lt;dir_path&gt; are used as the target keyspace/table name. For example, to load an sstable named ma-1-big-Data.db into keyspace1/standard1, you will need to have the files ma-1-big-Data.db and ma-1-big-Index.db in a directory /path/to/keyspace1/standard1/. The tool will create new sstables, and does not clean up your copied files.</p>
 <p>Several of the options listed below don’t work quite as intended, and in those cases, workarounds are mentioned for specific use cases.</p>
 <p>To avoid having the sstable files to be loaded compacted while reading them, place the files in an alternate keyspace/table path than the data directory.</p>
 <p>ref: <a class="reference external" href="https://issues.apache.org/jira/browse/CASSANDRA-1278">https://issues.apache.org/jira/browse/CASSANDRA-1278</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>

 <p>You can provide a cassandra.yaml file with the -f command line option to set up streaming throughput, and client and server encryption options. Only stream_throughput_outbound_megabits_per_sec, server_encryption_options, and client_encryption_options are read from yaml. You can override options read from cassandra.yaml with corresponding command line options.</p>

 <h2>Use a Config File for SSL Clusters<a class="headerlink" href="#use-a-config-file-for-ssl-clusters" title="Permalink to this headline">¶</a></h2>
