--------------------------------------
Summary: Insufficient performance of key-value operations via Java
thin client
Key: IGNITE-19664
URL: https://issues.apache.org/jira/browse/IGNITE-19664
Project: Ignite
Issue Type: Bug

Apache Ignite 3, rev. 0c68cbe3f016e508bd9d53ce5320c88acba1acff
YCSB key-value benchmarks:
https://github.com/gridgain/YCSB/tree/ae687c3bbd82eb7ce7b886af9a2ae2757457097c/ignite3
h1. Summary
The performance of key-value {{put()}} operations may be ~1.5 worse if
performed via Java thin client in comparison to similar {{put()}} operations
performed within an embedded node.
h1. Test 1. Thin client node
h2. Steps
Start a separate Ignite 3 node and a YCSB client which "100% inserts" workload.
1. Start an Apache Ignite 3 server node with the attached
{{ignite-config.conf}}.
2. Start a YCSB client node which performs {{KeyValueView#put}} operations.
YCSB command line options: {{-db site.ycsb.db.ignite3.IgniteClient -p
hosts=127.0.0.1 -s -P ./workloads/workloadc -threads 4 -p dataintegrity=true -p
operationcount=1000000 -p recordcount=1000000 -p disableFsync=true -p
useEmbedded=false -load}}

h1. Test 2. Embedded node
h2. Steps
The following step will start YCSB with an embedded Ignite 3 node within the
same JVM and the "100% insert" workload on that node.
1. Run YCSB with the {{useEmbedded=true}} parameter: {{-db
site.ycsb.db.ignite3.IgniteClient -p hosts=127.0.0.1 -s -P
./workloads/workloadc -threads 4 -p dataintegrity=true -p
operationcount=1000000 -p recordcount=1000000 -p disableFsync=true -p
useEmbedded=true -load}}
