_🤖_ <!-- Answer --> It seems like you are encountering an issue while using the HugeGraph Loader to import data into a MySQL backend after switching from RocksDB. The error message indicates that not all index fields are contained in the schema properties. Based on the error message and the provided schema and data files, it seems that the issue might be related to the field mapping in the `struct.json` file. The error message suggests that the index field 'id' is not contained in the schema properties '[ID, CODE, NAME, TYPE, length]'. To address your questions: 1. To use the loader to import data into a MySQL backend on a different node from the server, you need to ensure that the server is properly configured to connect to the remote MySQL database. Additionally, you need to provide the correct connection details in the loader command, including the host, port, username, and password. It's also important to ensure that the schema and data files are accessible from the machine where the loader is being executed. 2. The error is likely related to the field mapping in the `struct.json` file. You should review the field mapping for the 'link' edge label and ensure that the index field 'id' is correctly mapped to the schema properties. Here are a few steps you can take to troubleshoot the issue: - Double-check the field mapping in the `struct.json` file for the 'link' edge label to ensure that the index field 'id' is correctly mapped to the schema properties. - Verify that the schema and data files are accessible from the machine where the loader is being executed. - Ensure that the MySQL backend is properly configured and accessible from the server. If the issue persists, please provide more details about the field mapping in the `struct.json` file and any relevant error messages, and I can assist you further. --- This response is meant to be useful and save you time.
