GitHub user dosubot[bot] added a comment to the discussion: Secondary index and full tet query in Hugegraph
<!-- Answer --> I couldn't find specific information on whether HugeGraph's secondary index is dependent on external storage or search servers. However, HugeGraph supports various storage backends for storing secondary indexes, including Cassandra, ScyllaDB, HBase, RocksDB, MySQL, Palo, PostgreSQL, and Hstore <sup>[[1]](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-server/hugegraph-dist/src/main/java/org/apache/hugegraph/dist/RegisterUtil.java)</sup>. Unfortunately, details on how secondary indexes are stored internally across these different storage backends are not available. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* --- <sup>Help Dosu learn!
