> As part of the partition storage implementation , it is necessary to implement an index cleanup mechanism for cases when transactions are aborted and a rollback is required. This cleanup process should ensure that any index updates made during the transaction are properly removed to maintain the integrity.
> This mechanism should be abstract enough so that it can be later used for the garbage collection.
> https://issues.apache.org/jira/browse/IGNITE-17673 contains a pseudo-code for the index cleanup algorithm
