Refactor RocksDB clearThreshold ------------------------------- Key: ISPN-8241 URL: https://issues.jboss.org/browse/ISPN-8241 Project: Infinispan Issue Type: Sub-task Affects Versions: 9.1.0.Final Reporter: Ryan Emerson Assignee: Ryan Emerson Fix For: 9.2.0.Final Currently the RocksDB store utilises a "clearThreshold" to try to delete entries individually before deleting and re-initiating the database. We should deprecate this threshold and always delete/reinit the database. Currently when deleting the database, we utilise Util.recursiveFileRemove which does not confirm that the file has actually been deleted. Instead, we should provide a nio based implementation instead, similar to the one stated [here|https://stackoverflow.com/questions/779519/delete-directories-recurs...]. This has the advantage that an IOException is thrown by java.nio.file.Files::delete
