A file writer that can also multicast data to multiple readers (Streams v2)
bufferSize - total maximum amount of memory (in bytes) that can be used for buffering transferred data. Default value is 1MB.
The memory buffer contains last chunks of data that went through the writing pipeline.
Readers always try to read from the memory buffer first. If the memory buffer is big enough or the reading pipeline is fast enough the streaming is done completely from the memory buffer.
Creates a readable stream. Readable streams can be created and used at any time, even if the writing pipeline is finished and the instance of ReadableFileWriter is destroyed.
Any number of readable streams can be created.
highWaterMark - this value is passed to all calls to
fs.createReadStream that ReadableFileWriter makes under the hood during the streaming. Default value is 128KB.
Clients should listen to
error events on the instance of ReadableFileWriter and listen to
error events on all created readable streams.
ReadableFileWriter propagates errors from the writing pipeline to all reading pipelines. It allows clients to gracefuly stop reading pipelines without leaking resources.
