Abstract
The described technology is generally directed towards replicating a filesystem namespace from a source system such as a source node cluster to a target system such as a target node cluster. Directory transfer tasks processed at the source are sent to the target build a replica of a hierarchical namespace on a target cluster, in which the namespace contains the directories and files, with the file content temporarily absent. Files transfer tasks processed at the source are sent to the target to write the content into the files, generally after namespace creation is complete. Directory transfer is recursive, as one directory transfer task creates another directory transfer task for each of its child directories, and can be concurrent and sent as bulk transfer requests for efficiency in reducing overall latency overhead. File content transfer can transfer the content of multiple small files in a single transfer task request.
