public class FsRepository
extends BlobStoreRepository

Shared file system implementation of the BlobStoreRepository

Shared file system repository supports the following settings

location

Path to the root of repository. This is mandatory parameter.

concurrent_streams

Number of concurrent read/write stream (per repository on each node). Defaults to 5.

chunk_size

Large file can be divided into chunks. This parameter specifies the chunk size. Defaults to not chucked.

compress

If set to true metadata files will be stored compressed. Defaults to false.

Constructor Details

FsRepository

public FsRepository(RepositoryMetadata metadata,
 Environment environment,
 org.elasticsearch.xcontent.NamedXContentRegistry namedXContentRegistry,
 ClusterService clusterService,
 BigArrays bigArrays,
 RecoverySettings recoverySettings)

Constructs a shared file system repository.

Method Details

createBlobStore

protected BlobStore createBlobStore()
                             throws Exception

Description copied from class: BlobStoreRepository

Creates new BlobStore to read and write data.

Specified by:

createBlobStore in class BlobStoreRepository

Throws:

Exception

chunkSize

protected ByteSizeValue chunkSize()

Description copied from class: BlobStoreRepository

Returns data file chunk size.

This method should return null if no chunking is needed.

Overrides:

chunkSize in class BlobStoreRepository

Returns:

chunk size

hasAtomicOverwrites

public boolean hasAtomicOverwrites()

Overrides:

hasAtomicOverwrites in class BlobStoreRepository

Returns:

whether this repository performs overwrites atomically. In practice we only overwrite the `index.latest` blob so this is not very important, but the repository analyzer does test that overwrites happen atomically. It will skip those tests if the repository overrides this method to indicate that it does not support atomic overwrites.
