Hello! I saw these three pr #2518 #2519 and apache/hugegraph-doc#354. This issue needs is to in scripts/example.groovy script file automatically detect the conf/graphs/hugegraph.properties file in the backend is rocksdb, if so change it to memory, But at the same time do not override the original conf/graphs/hugegraph.properties file?

Hello! I saw these three pr #2518 #2519 and apache/incubator-hugegraph-doc#354. This issue needs is to in scripts/example.groovy script file automatically detect the conf/graphs/hugegraph.properties file in the backend is rocksdb, if so change it to memory, But at the same time do not override the original conf/graphs/hugegraph.properties file?

The essence of this issue is that when using Gremlin-Console Stand-alone in offline mode, some unexpected problems occur when using the RocksDB backend (the cause of which has not yet been identified). Therefore, a temporary switch to using the memory backend is suggested to circumvent it.

To completely resolve this issue, it is necessary to identify and address the errors related to using the RocksDB backend.
