Method Detail

persistent

public boolean persistent()

Description copied from interface: IndexStore

Is the store a persistent store that can survive full restarts.

backingStoreTotalSpace

public ByteSizeValue backingStoreTotalSpace()

Description copied from interface: IndexStore

Returns the backing store total space. Return -1 if not available.

backingStoreFreeSpace

public ByteSizeValue backingStoreFreeSpace()

Description copied from interface: IndexStore

Returns the backing store free space. Return -1 if not available.

canDeleteUnallocated

public boolean canDeleteUnallocated(ShardId shardId)

Description copied from interface: IndexStore

Returns true if this shard is allocated on this node. Allocated means that it has storage files that can be deleted using IndexStore.deleteUnallocated(org.elasticsearch.index.shard.ShardId).

Specified by:

canDeleteUnallocated in interface IndexStore

Overrides:

deleteUnallocated

public void deleteUnallocated(ShardId shardId)
                       throws java.io.IOException

Description copied from interface: IndexStore

Deletes this shard store since its no longer allocated.

Specified by:

deleteUnallocated in interface IndexStore

Overrides:

deleteUnallocated in class AbstractIndexStore

Throws:

java.io.IOException

shardLocations
