Set `properties.ssl.endpoint.identification.algorithm` to `none` to bypass the verification of CA certificates and resolve SSL handshake failure. This parameter can be set to either `https` or `none`. By default, it is `https`.

To monitor Kafka metrics in Grafana, set `properties.statistics.interval.ms` to a non-zero value. The granularity is 1000ms.

Starting with version 2.0, the default value for `properties.message.timeout.ms` has changed from 5 seconds to **5 minutes**, aligning with the default setting in the [official Kafka library](https://github.com/confluentinc/librdkafka/blob/master/CONFIGURATION.md).

To monitor Kafka metrics in Grafana, set `properties.statistics.interval.ms` to a non-zero value. The granularity is 1000ms.

The additional Kafka parameters `queued.min.messages` and `queued.max.messages.kbytes` are specified with `properties.queued.min.messages` and `properties.queued.max.messages.kbytes`, respectively, when creating the source.
