@kezhenxu94 For better 3rd party integration, we still need to evaluate the ways to update LAL and MAL in the runtime. Of course, the OAL should be on the radar, but considering it is heavier than these two, let's focus on LAL and MAL now. I have talked with people around about the MAL and LAL use case, this is really required because people are keeping add metrics analysis with time. From a tech perspective, groovy should be easy to support, the biggest challenge is about the streaming process. We need to support uninstall the existing process and tolerate `worker not found` in `RemoteServiceHandler`. Also, the update should be supported in 2 ways. 1. Dynamic configuration setting, like alarm setting. 2. File change monitoring(`MultipleFilesChangeMonitor`), then, in single-node mode or dev mode, we don't need to use (1), as it is clearly more complex than directly changing file I know, @kezhenxu94 have concerns about the security issue, we don't recommend definitely expose the script to the user, but use a system to assemble that. In further, we could have a better API set to assemble this script and avoid security issues. At the last, about the storage format change, it is more about the MAL change, especially when face H2/MySQL/PostgreSQL, which could be a load for the storage, but once this is open, users should take care of it. New metrics installation about these 2, need to check whether the entity(table) exists, if yes, we should follow a new config to determine whether OAP should `delete the entity` or `reject the change and output an error log`. @apache/skywalking-committers Welcome to discuss and comment.
