ClickBench测试

数据准备

1. 在压力机中执行如下命令，下载数据集压缩包，并解压：

   wget https://datasets.clickhouse.com/hits_compatible/hits.tsv.gz
   gunzip hits.tsv.gz

2. 在PolarDB-X的主实例中执行如下SQL，创建测试数据库和表：

3. 导入数据

   在压力机上，将如下命令保存为load.sh，并执行sh load.sh进行导入数据：

   java -Xmn4g -Xmx6g -jar batch-tool.jar -h127.0.0.1 -P3306 -uroot -pPassword -D clickbench -o import -t hits -s "       " -pro 1 -con 16 -minConn 8 -maxConn 16 -batchSize 100 -f hits.tsv -quote AUTO 2>&1 >> hits.log

   说明

   其中batch-tool.jar的安装以及使用说明，请参见使用Batch Tool工具导入导出数据。

   参数说明：

   参数名称	说明
   -h	数据库连接地址。
   -P	数据库端口号。
   -u	数据库账号。
   -p	账号对应的密码。
   -D	数据库名称，本例中为clickbench。
   -t	数据表名称，本例中为hits。
   -s	数据集解压后hits.tsv文件的数据分隔符，本例中为制表符（Tab）。
   -f	数据文件名称，本例中为hits.tsv。
   -Xmn	JVM新生代大小，可根据机器配置适当调整。
   -Xmx	JVM最大堆内存大小，可根据机器配置适当调整。

   说明

   以上参数，可根据实际情况替换。

4. 导入数据完成后，在clickbench数据库中执行如下SQL，为hits表创建列存索引：

   CREATE CLUSTERED COLUMNAR INDEX cci_hits ON hits(EventDate) PARTITION BY HASH(`UserID`) PARTITIONS 64;

   说明

   更多信息，请参见列存索引（CCI）。

数据库参数调优

SET GLOBAL RECORD_SQL = false;
SET GLOBAL MPP_METRIC_LEVEL = 0;
SET GLOBAL ENABLE_CPU_PROFILE = false;
SET GLOBAL ENABLE_BACKGROUND_STATISTIC_COLLECTION=false;
SET GLOBAL ENABLE_STATISTIC_FEEDBACK=false;
SET GLOBAL ENABLE_MPP_SERIALIZED_CHUNK_COMPRESSION = true;
SET GLOBAL ENABLE_OSS_COMPATIBLE = false;
SET GLOBAL MPP_TASK_LOCAL_MAX_BUFFER_SIZE = 32000000000;
SET GLOBAL MPP_OUTPUT_MAX_BUFFER_SIZE = 32000000000;
SET GLOBAL MPP_EXCHANGE_MAX_RESPONSE_SIZE = 32000000000;
SET GLOBAL ENABLE_STREAM_PARTIAL_AGG = true;
SET GLOBAL ENABLE_TRANSPARENT_PARTIAL_AGG = true;
SET GLOBAL ENABLE_SIMPLIFY_GROUP_BY_RULE = true;

执行测试脚本

1. 在压力机中保存如下代码为文件click.sh，并根据实际情况替换click.sh中的-h、-P、-u、-D参数：

   sql_queries=("SELECT COUNT(*) FROM hits;"
       "SELECT COUNT(*) FROM hits WHERE AdvEngineID <> 0;"
       "SELECT SUM(AdvEngineID), COUNT(*), AVG(ResolutionWidth) FROM hits;"
