背景
TPCC, TPCB是工业标准的OLTP类型业务的数据库测试，包含大量的读、写、更新、删除操作。
7*24小时强压耐久测试，主要看数据库在长时间最大压力下的 性能、稳定性、可靠性。
测试CASE ：
1、1000万 tpcc
2、1亿 tpcb
测试时长7天。
测试环境
与如下测试同一台ECS虚拟机环境。
《PostgreSQL 11 tpcc 测试(103万tpmC on ECS) - use sysbench-tpcc by Percona-Lab》
《(TPC-H测试 SF=10,SF=200) PostgreSQL 11 vs 10 vs Deepgreen》
《PostgreSQL 11 100亿 tpcb 性能测试 on ECS》

PS:
实际上最初测试的是TPCC 2亿耐久(2.5TB左右的活跃数据)，发现压力基本上都在IO上（因为活跃数据2.5TB，已远远超出机器的内存），平均TPS 3千(18万 tpmC)。
1、1000万 tpcc 耐久测试
1、清空
./tpcc.lua --pgsql-host=/tmp --pgsql-port=1921 --pgsql-user=postgres --pgsql-db=newdb --threads=64 --tables=10 --scale=100 --trx_level=RC --db-ps-mode=auto --db-driver=pgsql cleanup
2、初始化数据
export pgsql_table_options="tablespace tbs1"
export pgsql_index_options="tablespace tbs2"
./tpcc.lua --pgsql-host=/tmp --pgsql-port=1921 --pgsql-user=postgres --pgsql-db=newdb --threads=64 --tables=10 --scale=100 --trx_level=RC --db-ps-mode=auto --db-driver=pgsql --use_fk=0 prepare
3、持续7*24小时，强压耐久测试
./tpcc.lua --pgsql-host=/tmp --pgsql-port=1921 --pgsql-user=postgres --pgsql-db=newdb --threads=64 --tables=10 --scale=100 --trx_level=RC --db-ps-mode=auto --db-driver=pgsql --time=604800 --report-interval=1 --enable_purge=no run
初始化结束时，100多GB。
4、shell
#!/bin/bash
./tpcc.lua --pgsql-host=/tmp --pgsql-port=1921 --pgsql-user=postgres --pgsql-db=newdb --threads=64 --tables=10 --scale=100 --trx_level=RC --db-ps-mode=auto --db-driver=pgsql cleanup export pgsql_table_options="tablespace tbs1"
export pgsql_index_options="tablespace tbs2"
./tpcc.lua --pgsql-host=/tmp --pgsql-port=1921 --pgsql-user=postgres --pgsql-db=newdb --threads=64 --tables=10 --scale=100 --trx_level=RC --db-ps-mode=auto --db-driver=pgsql --use_fk=0 prepare ./tpcc.lua --pgsql-host=/tmp --pgsql-port=1921 --pgsql-user=postgres --pgsql-db=newdb --threads=64 --tables=10 --scale=100 --trx_level=RC --db-ps-mode=auto --db-driver=pgsql --time=604800 --report-interval=1 --enable_purge=no run
结果
1、初始化结束时，100多GB。
截取运行至8000秒（约2.2小时）时的TPS： 2万左右。

结果 8.66万 tps
7*24小时压测，数据库完成了523.8亿个事务，50几次freeze，性能平稳8.66万 tps 。
小结
1、1000万 tpcc测试，在16小时压测后，约1.8W tps，108 万tpmC。
由于TPCC不断有数据写入，29小时后，活跃数据量接近2TB，IO waiting成为瓶颈，TPS下降到1.3万左右。
2、1亿 tpcb测试，7天强压，性能平稳， 完成了523.8亿个事务，平均 tps 8.66万
