----------------------------------------

             Summary: Metastore read-only mode reduces the node start time
                 Key: IGNITE-10034
                 URL: https://issues.apache.org/jira/browse/IGNITE-10034
             Project: Ignite
          Issue Type: Bug
    Affects Versions: 2.7, 2.8
            Reporter: Maxim Muzafarov


Currently, note startup routine performs 2-times reading WAL:
* read WAL to restore Metastore in read-only mode ({{GridCacheDatabaseSharedManager#readMetastore}})
* read WAL to perform binary memory recovery({{GridCacheDatabaseSharedManager#restoreBinaryMemory}})

In the case of huge WAL it dramatically reduces the node stat time. We should restore Metastorage in read-only mode and binary memory consistency within single WAL iteration.
