Poll interval

In order for the consumer offset mapping functionality to work, both of the following requirements must be met:

• K2K must be configured to publish offset mappings.

• The k2k-offset-mapping application must be configured and deployed.

Without both components active, consumer group offsets on the target cluster will not be translated.

The k2k-offset-mapping application works by periodically polling the source cluster's consumer group API to retrieve the latest committed offsets for each group. It then uses the published offset mappings to translate these offsets and commit the corresponding positions on the target cluster.

The polling interval is configurable, allowing the balance between synchronization freshness and the load placed on the source cluster to be configured.
