>                 URL: https://issues.apache.org/jira/browse/IGNITE-8189
>             Project: Ignite
>          Issue Type: Improvement
>          Components: zookeeper
>            Reporter: Sergey Chugunov
>            Assignee: Amelchev Nikita
>            Priority: Major
>
> Three issues need to be improved in implementation:
> * two more deleteIfExists methods within the *deleteFutureData* to be included in batching
*deleteAll* operation;
> * if request exceeds ZooKeeper max size limit fallback to one-by-one deletion should
be used (related ticket IGNITE-8188);
> * ZookeeperClient#deleteAll implementation may throw NoNodeException is case of concurrent
operation removing the same nodes, in this case fallback to one-by-one deletion should be
used too.
