Store buffered events in separate Infinispan cache

    XMLWordPrintable

Details

    Description

      Currently, when using the Infinispan buffer, we store the LogMinerEvent instances in a collection that is part of the Transasction instance.  This means that when a transaction is loaded from the cache all its events are also hydrated which can waste memory or lead to OOME problems.  

      As an alternative, the LogMinerEvent instances should be stored in their own cache and looked up during commit or rollback time based on a range query based on the transaction's unique id.

          Bug - A problem that impairs or prevents the functions of the product. DBZ-4138 Oracle connector with Infinispan SPI corrupts during runtime

          • 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.
