Examples with KernelTransactionsSnapshot org.neo4j.kernel.impl.api.KernelTransactionsSnapshot used on opensource projects

Example 1 with KernelTransactionsSnapshot

use of org.neo4j.kernel.impl.api.KernelTransactionsSnapshot in project neo4j by neo4j.

the class NeoStoreDataSource method buildStorageEngine.

private StorageEngine buildStorageEngine(PropertyKeyTokenHolder propertyKeyTokenHolder, LabelTokenHolder labelTokens, RelationshipTypeTokenHolder relationshipTypeTokens, LegacyIndexProviderLookup legacyIndexProviderLookup, IndexConfigStore indexConfigStore, Runnable schemaStateChangeCallback, SynchronizedArrayIdOrderingQueue legacyIndexTransactionOrdering) {
    // TODO we should break this dependency on the kernelModule (which has not yet been created at this point in
    // TODO the code) and instead let information about generations of transactions flow through the StorageEngine
    // TODO API
    Supplier<KernelTransactionsSnapshot> transactionSnapshotSupplier = () -> kernelModule.kernelTransactions().get();
    RecordStorageEngine storageEngine = new RecordStorageEngine(storeDir, config, idGeneratorFactory, eligibleForReuse, idTypeConfigurationProvider, pageCache, fs, logProvider, propertyKeyTokenHolder, labelTokens, relationshipTypeTokens, schemaStateChangeCallback, constraintSemantics, scheduler, tokenNameLookup, lockService, schemaIndexProvider, indexingServiceMonitor, databaseHealth, labelScanStoreProvider, legacyIndexProviderLookup, indexConfigStore, legacyIndexTransactionOrdering, transactionSnapshotSupplier);
    // We pretend that the storage engine abstract hides all details within it. Whereas that's mostly
    // true it's not entirely true for the time being. As long as we need this call below, which
    // makes available one or more internal things to the outside world, there are leaks to plug.
    storageEngine.satisfyDependencies(dependencies);
    return life.add(storageEngine);
