----------------------------------------
Summary: Overall log cache usage doesn't respect the limit
Key: KUDU-2064
URL: https://issues.apache.org/jira/browse/KUDU-2064
Project: Kudu
Issue Type: Bug
Components: log
Affects Versions: 1.4.0
Reporter: Jean-Daniel Cryans
Looking at a fairly loaded machine (10TB of data in LBM, close to 10k tablets),
I can see in the mem-trackers page that the log cache is using 1.83GB, that it
peaked at 2.82GB, with a 1GB limit. It's consistent on other similarly loaded
tservers. It's unexpected.
Looking at the per-tablet breakdown, they all have between 0 and a handful of
MBs.
