Summary: Cache generated workflow PNG files
Key: OOZIE-3060
URL: https://issues.apache.org/jira/browse/OOZIE-3060
Project: Oozie
Issue Type: Improvement
Affects Versions: 4.3.0
Reporter: Andras Piros
Fix For: 5.0.0
After OOZIE-2406 we can generate workflow PNGs w/ an affordable CPU / heap
footprint.
Now it's time to cache:
# PNGs of the workflows already in some end state
# w/ configurable TTL (default: 15 minutes)
# to temp files
# using e.g. Guava's {{LoadingCache}}
