背景

TPCC, TPCB是工業標準的OLTP類型業務的數據庫測試，包含大量的讀、寫、更新、刪除操作。

7*24小時強壓耐久測試，主要看數據庫在長時間最大壓力下的 性能、穩定性、可靠性。

測試CASE ：

1、1000萬 tpcc

2、1億 tpcb

測試時長7天。

測試環境

與如下測試同一臺ECS虛擬機環境。

《PostgreSQL 11 tpcc 測試(103萬tpmC on ECS) - use sysbench-tpcc by Percona-Lab》

《(TPC-H測試 SF=10,SF=200) PostgreSQL 11 vs 10 vs Deepgreen》

《PostgreSQL 11 100億 tpcb 性能測試 on ECS》

shared_buffer=300G use huge page

PS:

實際上最初測試的是TPCC 2億耐久(2.5TB左右的活躍數據)，發現壓力基本上都在IO上（因為活躍數據2.5TB，已遠遠超出機器的內存），平均TPS 3千(18萬 tpmC)。

1、1000萬 tpcc 耐久測試

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、初始化數據

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、持續7*24小時，強壓耐久測試

./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

初始化結束時，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

結果

1、初始化結束時，100多GB。

截取運行至8000秒（約2.2小時）時的TPS： 2萬左右。

結果 8.66萬 tps

7*24小時壓測，數據庫完成了523.8億個事務，50幾次freeze，性能平穩8.66萬 tps 。

小結

1、1000萬 tpcc測試，在16小時壓測后，約1.8W tps，108 萬tpmC。

由于TPCC不斷有數據寫入，29小時后，活躍數據量接近2TB，IO waiting成為瓶頸，TPS下降到1.3萬左右。

2、1億 tpcb測試，7天強壓，性能平穩， 完成了523.8億個事務，平均 tps 8.66萬
