Connector max ; When configuring the JDBC Source Connector in Apache Kafka Connect, setting

for a Connector max, JDBC Source Connector in Apache Kafka Connect, setting tasks.max=5 should ideally create five tasks to parallelize the data extraction from the database. However, if only one task is created, there are a few potential reasons for this:

STEP FOR Connector max

1. Configuration Issue: Double-check your connector configuration and make sure that tasks.max is set to 5 correctly. Ensure there are no typos or syntax errors in the configuration file.
2. Connector Class Support: Verify that the JDBC Source Connector you are using supports multiple tasks. Not all connectors are designed to be parallelized, and some may only support a single task. Check the documentation or the specific connector’s capabilities to confirm if it supports multiple tasks.
3. Database Connection Limitations: Depending on your database’s configuration or limitations, it may not allow multiple connections or restrict the number of concurrent connections. This can prevent the creation of additional tasks. Check your database settings or consult with your database administrator to ensure that multiple connections are allowed.
4. Available Resources: The number of tasks that can be created depends on the available resources, such as CPU and memory, on the Kafka Connect worker nodes. If there are insufficient resources to accommodate multiple tasks, only a single task may be created. Ensure that your Kafka Connect cluster has enough resources to support the desired number of tasks.

By investigating these factors, you should be able to determine why only one task is being created for your JDBC Source Connector and take appropriate actions to resolve the issue.
