Build under test: Ignite 3, rev. 1e8959c0a000f0901085eb0b11b37db4299fa72a
Benchmark:
[https://github.com/gridgain/YCSB/blob/ycsb-2024.14/ignite3/src/main/java/site/ycsb/db/ignite3/IgniteClient.java]
h1. Test environment
6 AWS VMs of type c5d.4xlarge:
* vCPU 16
* Memory 32
* Storage 400 NVMe SSD
* Network up to 10 Gbps
h1. Test
Start 3 Ignite nodes (one node per host). Configuration:
* raft.fsync=false
* partitions=16
* replicas=1
Start 3 YCSB clients (one client per host). Each YCSB client spawns 32 load
threads and works with own key range. Parameters:
* Client 1: {{-db site.ycsb.db.ignite3.IgniteClient -load -P
/opt/pubagent/poc/config/ycsb/workloads/workloadc -threads 32 -p
hosts=192.168.208.221,192.168.210.120,192.168.211.201 -p recordcount=15300000
-p warmupops=100000 -p dataintegrity=true -p measurementtype=timeseries -p
status.interval=1 -p partitions=16 -p insertstart=5100000 -p
insertcount=5000000 -s}}
* Client 2: {{-db site.ycsb.db.ignite3.IgniteClient -load -P
/opt/pubagent/poc/config/ycsb/workloads/workloadc -threads 32 -p
hosts=192.168.208.221,192.168.210.120,192.168.211.201 -p recordcount=15300000
-p warmupops=100000 -p dataintegrity=true -p measurementtype=timeseries -p
status.interval=1 -p partitions=16 -p insertstart=0 -p insertcount=5000000 -s}}
* {{Client 3: {{-db site.ycsb.db.ignite3.IgniteClient -load -P
/opt/pubagent/poc/config/ycsb/workloads/workloadc -threads 32 -p
hosts=192.168.208.221,192.168.210.120,192.168.211.201 -p recordcount=15300000
-p warmupops=100000 -p dataintegrity=true -p measurementtype=timeseries -p
status.interval=1 -p partitions=16 -p insertstart=10200000 -p
insertcount=5000000 -s}}}}
h1. Results
Results from each client are in the separate files (attached).
>From these files we can draw transactions-per-second graphs:
!cl1.png!!cl2.png!!cl3.png!
Take a look at these sinks. We need to investigate the cause of them.
