> 单机版
> benchmark 并发创建对齐序列，iotdb/bm均不报错，但是部分序列没创建成功。
> 复现流程
> 1. 192.168.10.64 72C256G
> MAX_HEAP_SIZE="192G"
> MAX_DIRECT_MEMORY_SIZE="32G"
> mlog_buffer_size=10485760
> schema_engine_mode=Schema_File
> 2. benchmark运行附件中的脚本
> benchmark在本机路径/data/liuzhen_test/weektest/benchmark_tool_v13
> （0620的benchmark）
> 主要配置
> DEVICE_NUMBER=500
> SENSOR_NUMBER=200000
> CLIENT_NUMBER=20
> GROUP_NUMBER=100
> VECTOR=true
> LOOP=1
> BATCH_SIZE_PER_WRITE=1

> Create schema cost 1341.63 second
> Test elapsed time (not include schema creation): 311.88 second
> 测试脚本见附件
> 3. benchmark写入完成后，进行验证
> ./sbin/start-cli.sh -e "count timeseries root.** group by level=5; "
> 每个设备下应该有20万个序列，共500个设备。实际：
