ShardStoreInfo

public ShardStoreInfo(java.lang.String allocationId, boolean inSync, java.lang.Exception storeException)

ShardStoreInfo

public ShardStoreInfo(long matchingBytes)

ShardStoreInfo

public ShardStoreInfo(StreamInput in) throws java.io.IOException

Throws:

java.io.IOException

Method Details

isInSync

public boolean isInSync()

Returns true if the shard copy is in-sync and contains the latest data. Returns false if the shard copy is stale or if the shard copy being examined is for a replica shard allocation.

getAllocationId

@Nullable public java.lang.String getAllocationId()

Gets the allocation id for the shard copy, if it exists.

hasMatchingSyncId

public boolean hasMatchingSyncId()

Returns true if the shard copy has a matching sync id with the primary shard. Returns false if the shard copy does not have a matching sync id with the primary shard, or this explanation pertains to the allocation of a primary shard, in which case matching sync ids are irrelevant.

getMatchingBytes

public long getMatchingBytes()

Gets the number of matching bytes the shard copy has with the primary shard. Returns Long.MAX_VALUE if hasMatchingSyncId() returns true. Returns -1 if not applicable (this value only applies to assigning replica shards).

getStoreException

@Nullable public java.lang.Exception getStoreException()

Gets the store exception when trying to read the store, if there was an error. If there was no error, returns null.

writeTo
