      I set max.queue.size It's 8192. Once I update 10000 pieces of data at a time, this lock may appear because the queue is full

    Description

      I use the debezium server with oracle， the oracle version is 19c.

      When I update 10000 pieces of data at a time, the debezium server no longer receives data after receiving dozens of pieces of data at the beginning

      Through thread dump, I found deadlock

          Bug - A problem that impairs or prevents the functions of the product. DBZ-2914 Oracle12С XStream. Sometimes CPU utilization of DBZ is very low.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
