<details>
|

<summary>See Details</summary>
|
||||
Both compression and decompression now supports "synchronous" stream operations. This means that whenever "concurrency" is set to 1, they will operate without spawning goroutines.
|
||||
|
||||
Stream decompression is now faster on asynchronous, since the goroutine allocation much more effectively splits the workload. On typical streams this will typically use 2 cores fully for decompression. When a stream has finished decoding no goroutines will be left over, so decoders can now safely be pooled and still be garbage collected.
|
||||
|
||||
While the release has been extensively tested, it is recommended to testing when upgrading.

It is important to use the "Close" function when you no longer need the Reader to stop running goroutines,

Goroutines will exit once an error has been returned, including `io.EOF` at the end of a stream.

Streams are decoded concurrently in 4 asynchronous stages to give the best possible throughput.

However, if you prefer synchronous decompression, use `WithDecoderConcurrency(1)` which will decompress data

as it is being requested only.

The buffer decoder does everything on the same goroutine and does nothing concurrently.
|
||||
It can however decode several buffers concurrently. Use `WithDecoderConcurrency(n)` to limit that.
|
||||
|
||||
The stream decoder operates on
|
||||
The stream decoder will create goroutines that:
|
||||
|
||||
* One goroutine reads input and splits the input to several block decoders.
|
||||
* A number of decoders will decode blocks.
|
||||
* A goroutine coordinates these blocks and sends history from one to the next.
|
||||
1) Reads input and splits the input into blocks.
|
||||
2) Decompression of literals.
|
||||
3) Decompression of sequences.
|
||||
4) Reconstruction of output stream.
|
||||
|
||||
So effectively this also means the decoder will "read ahead" and prepare data to always be available for output.
|
||||
|
||||
The concurrency level will, for streams, determine how many blocks ahead the compression will start.
|
||||
|
||||
Since "blocks" are quite dependent on the output of the previous block stream decoding will only have limited concurrency.
|
||||
|
||||
In practice this means that concurrency is often limited to utilizing about 2 cores effectively.
