Enum Constant Summary
Enum Constants Enum Constant Description Fs
Default file system implementation.Hybridfs
The hybridfs type is a hybrid of niofs and mmapfs, which chooses the best file system type for each type of file based on the read access pattern.Mmapfs
The MMap FS type stores the shard index on the file system (maps to Lucene MMapDirectory) by mapping a file into memory (mmap).Niofs
The NIO FS type stores the shard index on the file system (maps to Lucene NIOFSDirectory) using NIO. -

Fs
Default file system implementation. This will pick the best implementation depending on the operating environment, which is currently hybridfs on all supported systems but is subject to change. -
Niofs
The NIO FS type stores the shard index on the file system (maps to Lucene NIOFSDirectory) using NIO. It allows multiple threads to read from the same file concurrently. It is not recommended on Windows because of a bug in the SUN Java implementation and disables some optimizations for heap memory usage. -
Mmapfs
The MMap FS type stores the shard index on the file system (maps to Lucene MMapDirectory) by mapping a file into memory (mmap). Memory mapping uses up a portion of the virtual memory address space in your process equal to the size of the file being mapped. Before using this class, be sure you have allowed plenty of virtual address space. -
Hybridfs
The hybridfs type is a hybrid of niofs and mmapfs, which chooses the best file system type for each type of file based on the read access pattern. Currently only the Lucene term dictionary, norms and doc values files are memory mapped. All other files are opened using Lucene NIOFSDirectory. Similarly to mmapfs be sure you have allowed plenty of virtual address space.
