/**
* Enter streaming mode.
*
* This mode is an extension to the pipeline mode, optimized for performance. It also buffers the
* commands on the client-side and sends them in one batch. The difference is that all results are
* discarded, although some implementations may choose to return them anyways. This allows us to
* apply some optimizations which make the execution of the commands significantly faster (up to
* 50%). It's obviously only useful for bulk writing operations.
*
* This mode is an extension to the default Redis API, the name of the method may also change in
* the future (batchWrite?, bulkWrite?). This mode may also implement more performance optimizing
* features later on.
