> 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!
