Storage Files and Directories
This is the manual for older MicroStream versions (Version < 5.0).
The new documentation (Version >= 5.0) is located at:
Using a Storage Live File Provider (
one.microstream.storage.types.StorageLiveFileProvider) allows to specify the location and naming rules for all storage related files.available properties are:
- BaseDirectory The Microstream storages location base directory. Contains channel directories and type dictionary file.
- DeletionDirectory If configured, the storage will not delete files. Instead of deleting a file it will be moved to this directory.
- TruncationDirectory If configured, files that will get truncated are copied into this directory.
- ChannelDirectoryPrefix Channel directory prefix string
- StorageFilePrefix Storage file prefix string
- StorageFileSuffix storage file extension
- TransactionsFilePrefix transactions file prefix
- TransactionsFileSuffix transaction file extension
- TypeDictionaryFileName filename of the type dictionary
StorageFileNameProvider fileNameProvider = StorageFileNameProvider.Builder()
.setChannelDirectoryPrefix("canal_")
.setDataFilePrefix ("canal_")
.setDataFileSuffix (".bin")
.setTransactionsFilePrefix("events_")
.setTransactionsFileSuffix(".bin")
.setTypeDictionaryFileName("typeDictionary.txt")
.createFileNameProvider ()
;
NioFileSystem fileSystem = NioFileSystem.New();
StorageLiveFileProvider fileProvider = Storage
.FileProviderBuilder (fileSystem)
.setDirectory (fileSystem.ensureDirectoryPath(WORKINGDIR))
.setDeletionDirectory (fileSystem.ensureDirectoryPath(DELETIONDIR))
.setTruncationDirectory(fileSystem.ensureDirectoryPath(TRUNCATIONDIR))
.setFileNameProvider (fileNameProvider)
.createFileProvider ()
