StreamingCSWriterView

StreamingCSWriterView allows for checkpoints with arbitrarily nested dictionaries/lists to be written in a streaming (incremental) manner by offering a "view" into a StreamingCSWriter.

StreamingShardedHFReader

StreamingShardedHFWriter

Writes a HuggingFace sharded checkpoint in a streaming manner rather than accumulating the full checkpoint into memory and then writing all shards at the end.
