起因

如果把很多地理數據可視化放入一個dashboard會出現這么個問題

?

環境

環境	版本
Ubuntu	18.04
apache-superset (pip install apache-superset)	0.37.1
Mysql	5.7
redis-cli	4.0.9

?

調研

[1]提到了二級緩存

[4]提到如果配置cache成功會有相關信息

?

?

準備工作

apt install redis

(virtualenv環境)pip install?redis

?

?

編輯

~/.virtualenvs/python3.6/lib/python3.6/site-packages/superset/config.py

所有需要cache字樣的全部配置成redis,具體改法見文末附錄

?

配置效果

啟動項目打開dashboard，log中會Serving from cache的字樣,說明配置成功

說明配置成功

?

如果依然出現下面SQL語句:

說明配置失敗

?

可視化效果

打開http://49.235.108.13:5000/superset/dashboard/3/

如果superset沒有redis就會出現一大堆的close wait以及在dashboard上會因為timeout導致無法顯示chart

?

相關命令

用SSH從遠程服務器批量復制文件到本地（注意要在本地電腦上執行以下命令，而不是云主機上）

scp -r appleyuchi@49.235.108.13:/home/appleyuchi/.virtualenvs/python3.6/lib/python3.6/site-packages/superset/config.py /home/appleyuchi scp -r /home/appleyuchi/config.py appleyuchi@49.235.108.13:/home/appleyuchi/.virtualenvs/python3.6/lib/python3.6/site-packages/superset
