     <div class="caution">
     It would be best to run CreateIndex() after Insert() without waiting for auto-indexing in your client code, even you can wait for the finishing auto createIndex function, which sometimes takes a long time.
     The backup files (e.g., ngt-meta.kvsdb) will be in your mount directory when vald-agent-ngt finishes indexing.
