isFileSynced

public boolean isFileSynced(java.lang.String nodePathName)

Determines whether a file-like entity with the given name has been "synced" (completely copied) to S3. Determination of "synced": - A nodeName of null or "" is always "not synced". - A nodeName that does not map to a valid node is always "not synced". - If the node for this nodeName does not have a binary property, this node is always "not synced" since such a node would never be copied to S3. - If the node for this nodeName is not in the nodeStore, this node is always "not synced". - Otherwise, the state is "synced" if the corresponding blob is completely stored in S3.

Specified by:

isFileSynced in interface ConsolidatedDataStoreCacheStatsMBean

Parameters:

nodePathName - - Path to the entity to check. This is a node path, not an external file path.

Returns:

true if the file is synced to S3.
