> The current architecture around the BLOB server and cache components seems rather patched up and has some issues regarding concurrency ([FLINK-6380]), cleanup, API inconsistencies / currently unused API ([FLINK-6329], [FLINK-6008]). These make future integration with FLIP-6 or extensions like offloading oversized RPC messages ([FLINK-6046]) difficult. We therefore propose an improvement on the current architecture as described below which tackles these issues, provides some cleanup, and enables further BLOB server use cases.
