-------------------------

             Summary: select count(*) :  overlapped data should be consumed first
                 Key: IOTDB-2445
                 URL: https://issues.apache.org/jira/browse/IOTDB-2445
             Project: Apache IoTDB
          Issue Type: Bug
          Components: Core/Server
    Affects Versions: 0.13.0
            Reporter: 刘珍
         Attachments: image-2022-01-19-18-54-45-825.png, image-2022-01-19-18-55-24-711.png

0.13.0 预发版1

复现用例:

测试机器:私有云32g内存,8cpu。benchmark和iotdb在同一台机器。

iotdb-env.sh :
MAX_HEAP_SIZE="16G"
MAX_DIRECT_MEMORY_SIZE="6G"

数据库开合并(默认)

1. benchmark产生乱序数据,配置文件见附件。
2.benchmark执行完成后,立即在cli执行(防止合并太快,把乱序下的文件合并完)下面的几条SQL(整个复制粘贴):
time ./sbin/start-cli.sh -e "flush "
time ./sbin/start-cli.sh -e "select s_0,s_1,s_2,s_3,s_4,s_5 into root.db.dev.s_0,root.db.dev.s_1,root.db.dev.s_2,root.db.dev.s_3,root.db.dev.s_4,root.db.dev.s_5 from root.test.g_0.d_0; "
{color:#DE350B}*time ./sbin/start-cli.sh -e "select count from root.test.g_0.d_0; "*{color}
time ./sbin/start-cli.sh -e "select count from root.db.dev; "
