-------------------------------------
Summary: [Debezium Informix Connector Unable to Commit Processed
Log Position]
Key: KAFKA-16311
URL: https://issues.apache.org/jira/browse/KAFKA-16311
Project: Kafka
Issue Type: Bug
Reporter: Maaheen Yasin
Attachments: connect logs.out
I am using Debezium Informix Source connector and JDBC Sink connector and the
below versions of Informix database and KAFKA Connect.
Informix Dynamic Server
14.10.FC10W1X2
Informix JDBC Driver for Informix Dynamic Server
4.50.JC10
KAFKA Version: 7.4.1-ce
*Expected Behavior:*
All tasks of the Informix source connector are running, and all messages are
being published in the topic. During the DDL Execution, the informix database
is put under single user mode and the DDL on the table on which CDC was
previously enabled was executed. After the database exits from the single user
mode, then the connector should be able to reconnect with the source database
and be able to publish messages in the topic for each new event.
*Actual Behavior:*
All tasks of the Informix source connector are running, and all messages are
being published in the topic. During the DDL Execution, the database is put
under single user mode and the DDL on the table on which CDC was previously
enabled was executed. After the database exits from the single user mode, the
source connector is able to reconnect with the database, however, no messages
are being published in the topic and the below error is being printed in the
KAFKA Connect Logs.
*[2024-02-22 15:54:34,913] WARN [kafka_devs|task-0|offsets] Couldn't commit
processed log positions with the source database due to a concurrent connector
shutdown or restart (io.debezium.connector.common.BaseSourceTask:349)*
The complete KAFKA Connect logs has been attached. Kindly comment on why this
issue is occurring and what steps should be followed to avoid this issue or to
resolve this issue.
Thanks.
