AI3, rev. 6b6f0cb6109d7906a980a31522a1b9c36f88e43a (Fri Oct 27)
The same benchmark still shows poor SELECTs performance on 2 server nodes.

Nodes logs, GC logs: [^6b6f0c-select-logs.zip.zip]
*UPD:* while 2 server nodes were in the test cluster, current run passed 1
server node host to the client:
{code:java}
Command line: -db site.ycsb.db.ignite3.IgniteSqlClient -t -P
/opt/pubagent/poc/config/ycsb/workloads/workloadc -threads 1 -p
operationcount=10000 -p recordcount=10000 -p dataintegrity=true -p
measurementtype=timeseries -p hosts=192.168.1.52 -p operationcount=100000 -p
recordcount=100000 -s

> Ignite 3, rev. 7d188ac7ae068bd69ff0e6e6cfe5a32ac5749d17
> Benchmark:
> [https://github.com/gridgain/YCSB/blob/ycsb-2023.3/ignite3/src/main/java/site/ycsb/db/ignite3/IgniteSqlClient.java]
>
> The benchmark establishes an SQL {{Session}} and perform {{SELECTs}} via
> {{{}preparedStatement{}}}.
>
> Steps:
> * Run an Ignite cluster of 2 nodes with the attached config
> [^ignite-config.json] .
> ** *fsync = false*
> * Run the SQL YCSB benchmark in preload mode:
> ** {{-db site.ycsb.db.ignite3.IgniteSqlClient -load -P
> /opt/pubagent/poc/config/ycsb/workloads/workloadc -threads 1 -p
> recordcount=10000 -p dataintegrity=true -p measurementtype=timeseries -p
> hosts=192.168.1.60}}
> * Run the SQL YCSB benchmark in 100% read mode:
> ** {{-db site.ycsb.db.ignite3.IgniteSqlClient -t -P
> /opt/pubagent/poc/config/ycsb/workloads/workloadc -threads 1 -p
> operationcount=10000 -p recordcount=10000 -p dataintegrity=true -p
> measurementtype=timeseries -p hosts=192.168.1.60 -s}}
> * Observe the following average throughput on reads:
> !sql-2nodes-select.png!
> Server node's logs: [^sql-logs-2-server-nodes.zip]
> Repeat the test with only 1 server node and observe {*}~20x better throughput
> on reads{*}:
> !sql-1node-select.png!
