Caused by: java.io.IOException: java.sql.SQLException: Attempt to execute batch failed, exhausted retry times = 3 about flink-connector-clickhouse

[itinycheng]

This is an exception where writing ClickHouse fails, refer to: ClickHouseExecutor
The exception info above miss the original exception info, I can't figure out the cause of the exception.
In order to find out the problem, you'd better do some breakpoint test.

[zjialin]

请大神指教一下问题出在哪点

[itinycheng]

@zjialin
这个是upsert模式下的报错，因为有看到调用ClickHouseUpsertExecutor. executeBatch，具体报错原因从当前错误信息中还是找不出来，你最好本地断点测试下；
如果不必须用upsert模式就添加配置catalog.ignore-primary-key = true，ClickHouse的Mutation操作比较重，不是特别建议用，我生产基本是append模式 + TableEngine来做类似数据更新的操作；

[zjialin]

我设置catalog.ignore-primary-key = true 目前同样的错。

CREATE TABLE SOURCE_test1 (
id BIGINT,
user_name VARCHAR(64),
create_date TIMESTAMP(0),
create_date_test TIMESTAMP(0),
PRIMARY KEY(id) NOT ENFORCED
) WITH (
'connector' = 'mysql-cdc',
'hostname' = '10.96.183.42',
'port' = '32282',
'username' = 'root',
'password' = '',
'database-name' = 'test_flink',
'table-name' = 'test1'
);
CREATE TABLE SINK_test1 (
id BIGINT,
user_name STRING,
create_date TIMESTAMP(0),
create_date_test TIMESTAMP(0),
its_ck_sign TINYINT,
PRIMARY KEY(id) NOT ENFORCED
) WITH (
'connector' = 'clickhouse',
'url' = 'clickhouse://10.96.183.45:8123',
'username' = 'default',
'password' = '',
'database-name' = 'test_flink',
'table-name' = 'test1',
'sink.batch-size' = '500',
'sink.flush-interval' = '1000',
'catalog.ignore-primary-key' = 'true',
'sink.max-retries' = '5'

);
insert into SINK_test1(id,user_name,create_date,create_date_test) select * from SOURCE_test1;

); insert into SINK_test1(id,user_name,create_date,create_date_test) select * from SOURCE_test1;

catalog.ignore-primary-key = true 只在create catalog时候生效，生成的表是忽略主键的；你看字面意思就应该明白哈，或是仔细看下readme.md;

你建表语句去掉primary key 就可用append模式了，这个我后续会添加单独的的mode=append/upsert参数来标识；
