Re: Entering a busy loop when adding a new sink to the graph + checkpoint enabled

2024-03-10 Thread Hang Ruan
Hi, Xuyang & Daniel. I have checked this part of code. I think it is an expected behavior. As marked in code comments, this loop makes sure that the transactions before this checkpoint id are re-created. The situation Daniel mentioned will happen only when all checkpoint between 1 and 2

Hi, Danny. When the problem occurs, can you use flame graph to confirm whether the loop in this code is causing the busyness? Since I'm not particularly familiar with kafka connector, I can't give you an accurate reply. I think Hang Ruan is an expert in this field :). Hi, Ruan Hang. Can you

hi, 东树 隐藏sql中的敏感信息,这个需要外部的大数据平台来做。 比如:StreamPark 的变量管理,可以提前维护好配置信息,编写sql时引用配置,由平台提交至flink时解析sql并替换变量。 Best, Zhongqiang Gong 杨东树 于2024年3月10日周日 21:50写道: > 各位好, >考虑到数据库用户、密码安全性问题,使用FlinkSQL connector > jdbc时,请问如何对数据库的用户密码进行加密/隐藏呢。例如如下常用sql中的password: > CREATE TABLE wordcount_sink ( >

1. 目前 JDBC connector 本身不支持加密, 我理解可以在提交 SQL 给 SQL 文本来做加解密的操作,或者做一些变量替换来隐藏密码。 2. 可以考虑提前创建好 jdbc catalog,从而避免编写 DDL 暴露密码。 Best, Feng On Sun, Mar 10, 2024 at 9:50 PM 杨东树 wrote: > 各位好, >考虑到数据库用户、密码安全性问题,使用FlinkSQL connector > jdbc时,请问如何对数据库的用户密码进行加密/隐藏呢。例如如下常用sql中的password: > CREATE TABLE

各位好, 考虑到数据库用户、密码安全性问题,使用FlinkSQL connector jdbc时,请问如何对数据库的用户密码进行加密/隐藏呢。例如如下常用sql中的password: CREATE TABLE wordcount_sink ( word String, cnt BIGINT, primary key (word) not enforced ) WITH ( 'connector' = 'jdbc', 'url' = 'jdbc:mysql://localhost:3306/flink', 'username' = 'root',
