             Summary: FLIP-19: Improved BLOB storage architecture
                 Key: FLINK-6916
                 URL: https://issues.apache.org/jira/browse/FLINK-6916
             Project: Flink
          Issue Type: Improvement
          Components: Network
    Affects Versions: 1.4.0
            Reporter: Nico Kruber
            Assignee: Nico Kruber


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.

 for a full overview on the proposed changes.
