UNKNOWN_RESERVED_BYTES

public static final long UNKNOWN_RESERVED_BYTES

Sentinel value for cases where the shard does not yet know its reserved size so we must fall back to an estimate, for instance prior to receiving the list of files in a peer recovery.

StoreStats

public StoreStats()

StoreStats

public StoreStats(StreamInput in)
           throws IOException

Throws:

IOException

StoreStats

public StoreStats(long sizeInBytes,
 long totalDataSetSizeInBytes,
 long reservedSize)

Parameters:

sizeInBytes - the size of the store in bytes

totalDataSetSizeInBytes - the size of the total data set in bytes, can differ from sizeInBytes for shards using shared cache storage

reservedSize - a prediction of how much larger the store is expected to grow, or UNKNOWN_RESERVED_BYTES.

Method Details

add

public void add(StoreStats stats)

sizeInBytes

public long sizeInBytes()

getSizeInBytes

public long getSizeInBytes()

size

public ByteSizeValue size()

getSize

public ByteSizeValue getSize()

totalDataSetSize

public ByteSizeValue totalDataSetSize()

getTotalDataSetSize

public ByteSizeValue getTotalDataSetSize()

totalDataSetSizeInBytes

public long totalDataSetSizeInBytes()

getReservedSize

public ByteSizeValue getReservedSize()

A prediction of how much larger this store will eventually grow. For instance, if we are currently doing a peer recovery or restoring a snapshot into this store then we can account for the rest of the recovery using this field. A value of -1B indicates that the reserved size is unknown.

public void writeTo(StreamOutput out)
             throws IOException

Description copied from interface: Writeable

Write this into the StreamOutput.

Specified by:

writeTo in interface Writeable

Specified by:

toXContent in interface org.elasticsearch.xcontent.ToXContent

Throws:
