I am currently travelling and then attending Flink Forward. Will come back
to this after that.
Quick feedback:
- I am still thinking that the random suffix breaks the original idea of
the cached blobs.
- The blob manager counts references to files and does not delete them as
long as someone has a reference. That prevents deletion if multiple parties
work with the same jar.
- Properly handling rename and add reference in one lock, as well as
de-reference and delete in the same lock should fix it, I think
- The blob manager needs to make sure it has an exclusive directory, so
that no other process accesses the files. But I think that is the case already.
