复现流程
1. 机器
fit 192.168.130.1 (8C32G) /home/iotdb/db/master_0509_bc6c4af
MAX_HEAP_SIZE="20G"
MAX_DIRECT_MEMORY_SIZE="6G"
schema_engine_mode=Schema_File
fit 192.168.130.2 /home/benchmark/bm_20220322
2. bm 配置文件
放在/home/benchmark/bm_20220322/conf
3. 启动iotdb
4. 运行bm
/home/benchmark/bm_20220322下运行run.sh
cat run.sh
#!/bin/bash
time1=`date +%s`
cp -rp conf/config.properties.1 conf/config.properties
./benchmark.sh > 1.out &
cp -rp conf/config.properties.2 conf/config.properties
./benchmark.sh > 2.out &
wait
time2=`date +%s`
time=$(($time2-$time1))
echo "bing fa run : ${time} seconds." >> time_res.txt
