Description

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.
