    [ https://issues.apache.org/jira/browse/IGNITE-9418?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16623606#comment-16623606 ] 

Pavel Kovalenko commented on IGNITE-9418:
-----------------------------------------

Successful criteria: we shouldn't invoke org.apache.ignite.internal.processors.cache.persistence.file.FilePageStoreManager#initializeForCache synchronously during PME.

> Currently, we do creation for partition and index files during PME for starting caches at the beginning of org.apache.ignite.internal.processors.cache.persistence.GridCacheDatabaseSharedManager#readCheckpointAndRestoreMemory method.
> We should avoid this because sometimes it took a long time as we perform writing to disk.
>  If the cache was registered during PME we should initialize page store lazy or asynchronously.
