Hello Pinot developers, I’ve drafted a design doc <https://docs.google.com/document/d/1B_8k2XGMrxfFAo_g-MEjEPGj84Xy8YW4-yUiZ2BQkuE/edit#heading=h.2ic29gs71g43> about how to make Pinot servers able to use multiple data directories to keep segments, and how this can be enabled by extending the current tiered storage functionality. Please help review it and feel free to comment.
Thank you! best, Xiaobing
