      What is the captured database version and mode of deployment?

      Oracle Database 19, Docker

      What behaviour do you expect?

      LogMiner batch size is automatically increased within range if Oracle connector detects a lag from the current SCN.

      What behaviour do you see?

      LogMiner batch size remains unchanged.

      Do you see the same behaviour using the latest relesead Debezium version?

      Yes
