the class Recovery method performRecovery.

/**
 * Performs recovery of database described by provided layout.
 *
 * @param fs database filesystem
 * @param pageCache page cache used to perform database recovery.
 * @param tracers underlying operation tracers
 * @param config custom configuration
 * @param databaseLayout database to recover layout.
 * @param storageEngineFactory {@link StorageEngineFactory} for the storage to recover.
 * @param logProvider log provider
 * @param globalMonitors global server monitors
 * @param extensionFactories extension factories for extensions that should participate in recovery
 * @param providedLogFiles log files from database
 * @param forceRunRecovery to force recovery to run even if the usual checks indicates that it's not required.
 * In specific cases, like after store copy there's always a need for doing a recovery or at least to start the db, checkpoint and shut down,
 * even if the normal "is recovery required" checks says that recovery isn't required.
 * @throws IOException on any unexpected I/O exception encountered during recovery.
