------------------------------------
Summary: Write performance degradation
Key: HDDS-9232
URL: https://issues.apache.org/jira/browse/HDDS-9232
Project: Apache Ozone
Issue Type: Bug
Affects Versions: 1.3.0
Reporter: Mladjan Gadzic
It is observed on real cluster using unsecure Ozone HA (3 OMs, 3 SCMs, 3DNs)
that write performance degraded significantly after Ratis upgrade to 2.5.1
(https://issues.apache.org/jira/browse/HDDS-8382). At the time of writing this
ticket, it takes master branch ~25mins for 100k keys to be written, while it
took 1.3.0 release ~2mins for the same number of keys.
Test was done using single freon client on OM node. Command
{code:java}
ozone freon rk --bufferSize 4096 --factor THREE --keySize 10240 --numOfVolumes
1 --numOfBuckets 1 --numOfKeys 100000 --numOfThreads 10 --replication-type
RATIS {code}
was used for that purpose.
Commit before HDDS-8382, HDDS-8550 (sha
290e5f2ba1826a2084c1745e458872dc76c7ae91) did not exhibit degradation in write
performance.
