sql server2008 r2

有兼容sqlserver2008r2 的版本吗

You can use sqlserver cdc connector, but you could meet a jdk ssl problem, you can modify jre/lib/security/java.security. Ref to microsoft/mssql-jdbc#1803 (comment)

[gong]

I copy this document (https://github.com/apache/flink-cdc/blob/release-2.3/docs/content/connectors/sqlserver-cdc.md) to my java program but it have many exception。I don't know if it's incompatible。I have tried many versions of Pom.xml

You can paste your error log. I test sqlserver 2008 is ok.

May I look at your code?

[gong]

You need paste full error log, I think your erorr should not be relative with sqlserver cdc. You can refer test case code if you just test local. I use flink sql sqlserver cdc package to connect sqlserver by running flink sql in flink cluster.

I added these dependency,then it show this error.I tried to Ref to microsoft/mssql-jdbc#1803 (comment) but it didn't change

You can ref to UT and update your pom by ref sqlserver cdc pom, you lost some flink env package.

You can use release-2.4 branch and SqlServerParallelSourceExampleTest case. 2.3 version is cdc1.0. 2.4 version sqlserver cdc start to be cdc2.0.

[oganic]

I have another question: when I execute this program, I can listen to the database, but when I close and restart it, it doesn't read data from the breakpoint in database
