Description

AI3, rev. 8ebd9e842a2aaec5e1ae7e3b5e1cb36a040dc565

Benchmark: https://github.com/gridgain/YCSB/blob/ycsb-2023.7/ignite3/src/main/java/site/ycsb/db/ignite3/IgniteClient.java 

Cluster setup: 1 server node, aipersist, 25 partitions, raft.fsync=false

Steps

Run the mentioned key-value benchmark to preload data (10 million unique keys):

 

Command line: -db site.ycsb.db.ignite3.IgniteClient -load -P /opt/pubagent/poc/config/ycsb/workloads/workloadc -threads 1 -p recordcount=250000 -p warmupops=50000 -p dataintegrity=true -p measurementtype=timeseries -p status.interval=1 -p hosts=192.168.1.63 -p recordcount=10000000 -p operationcount=10000000 -s

Observe that all 10M keys have been loaded:

 

 

[INSERT], Return=OK, 10000000

 Run the 100% get operations over preloaded data:

 

Command line: -db site.ycsb.db.ignite3.IgniteClient -t -P /opt/pubagent/poc/config/ycsb/workloads/workloadc -threads 1 -p operationcount=250000 -p recordcount=250000 -p warmupops=50000 -p dataintegrity=true -p measurementtype=timeseries -p status.interval=1 -p hosts=192.168.1.63 -p recordcount=10000000 -p operationcount=10000000 -s

Expected result

All 10M keys were read without errors

Actual result

Reading 4341 keys out of 10M keys failed with exception like the following one:
