----------------------------------------
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.
