kafka-connect-tdengine's Issues

第二次调用一个执行了多次查询的方法会报Unable to establish connection

当一个方法内调用了多次查询



xml配置文件:

<!--  TDengine配置  -->
<bean id="druidDataSource" class="com.alibaba.druid.pool.DruidDataSource">

报错日志:

当一个方法内执行多次查询,第二次调用这个方法时就会报Unable to establish connection无法建立连接。版本是3.2.0

根据官方网站的技术文档，https://www.taosdata.com/chinese/12592.html 进行 sink尝试，在 sink-test.properties 中
name=TDengineSinkConnector
connector.class=com.taosdata.kafka.connect.sink.TDengineSinkConnector
tasks.max=1
topics=meters
connection.url=jdbc:TAOS://127.0.0.1:6030
connection.user=root
connection.password=taosdata
connection.database=power
db.schemaless=line
key.converter=org.apache.kafka.connect.storage.StringConverter
value.converter=org.apache.kafka.connect.storage.StringConverter

tasks.max=1 情况下，入库数据失败，改为大于等于2，可看到数据成功写入到TD。在 tasks.max=1的情况下，出错信息如下：

Consumption throws away the entire batch when encountering an error

Bug Description
kafka连接器在遇到不符合规范的数据，会丢弃整个batch，而不是将batch中可以插入的数据插入，丢弃错误数据。

To Reproduce
依据官方示例
https://docs.taosdata.com/third-party/kafka
将数据文件test-data.txt改为

meters,location=California.LosAngeles,groupid=2 current=11.8,voltage=221,phase=0.28 1648432611249000000
meters,location=California.LosAngeles,groupid=2 current=13.4,voltage=223,phase=0.29 1648432611250000000
errorline
meters,location=California.LosAngeles,groupid=3 current=10.8,voltage=223,phase=0.29 1648432611249000000
meters,location=California.LosAngeles,groupid=3 current=11.3,voltage=221,phase=0.35 1648432611250000000

即可复现
Screenshots
If applicable, add screenshots to help explain your problem.

Environment (please complete the following information):
TDengine Version TDengine-server-2.6.0.8-Linux-x64
taosdata-kafka-connect-TDengine Version 1.0.1

Additional Context
经过整体批重试后，会进入一个对批中每个记录的迭代，此时由于connection已经被关闭，丢失了数据库名，造成即使是正确的记录也无法插入，整个批次都被丢弃。详见log加粗部分

log如下

我将sink-demo.json其中的"connection.url": "jdbc:TAOS://127.0.0.1:6030"修改为"connection.url": "jdbc:TAOS-RS://127.0.0.1:6041?user=root&password=taosdata"就不会再出现问题了，怀疑是改成REST连接后，connection.user配置项不生效，只好在url上直接拼接了。

希望能验证这个问题并修复。

数据库版本：3.1.0.0
Kafka：2.2.2
现象：使用OpenTSDB JSON 协议格式。一直同步不过去，没办法查看日志
sink连接状态显示

sink-demo.json文件配置
