Hi > I have noticed that skywalking use heap buffer to cache tracing data.
It could cause data loss, but that is intentional. Because we need to keep memory safe. Back to what your asking, if you want to build a local file system based cache, I think you should submit a design, including 1. What is the file write/read model 2. When should activate this feature, and how 3. What is performance? And do you have available benchmark result between memory write and file write in high concurrency situation. more if you thing need to say. You could use this[1] as design doc template. Look forward to your detail.
