[jira] [Updated] (IGNITE-18558) Fix Meta Storage prefix reads

     [ https://issues.apache.org/jira/browse/IGNITE-18558?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Aleksandr Polovtcev updated IGNITE-18558:
-----------------------------------------
    Description: Meta Storage Manager prefix method implementations use {{KeyCriterion#nextKey}} method to create an upper bound of a prefix. This method is, unfortunately, incorrect, because it adds a 0 to the array, if the last byte overflows. It also uses signed arithmetic, while internal RocksDB implementation uses unsigned.
