Saving Kafka Connect Configurations

Describes how Kafka Connect configurations are saved during an upgrade.

Starting in EEP 6.0.0, the configuration for a previously installed version of Kafka Connect is stored in a folder with a timestamp.
  • Files are saved and overwritten by new configuration files:
    • when upgrading from 4.1.0 to 5.1.2.
    • when upgrading from 5.1.2 to 10.0.0.
  • Files are saved only (not overwritten):
    • when upgrading from 5.1.2 to 5.1.2.

Example

The following example shows the list of configuration files that are saved when upgrading from mapr-kafka-connect 5.1.2 (EEP 7.0.0) to mapr-kafka-connect 5.1.2 (EEP 7.0.1):
ls /opt/mapr/kafka/
