Replace blocking concurrent queue with non-blocking channel?

[wangjia184]

Write transactions are executed in a single thread via a blocking concurrent queue.

it is better to replace blocking queue with Channel.

The former blocks a thread when waiting for new data; The latter is totally non-blocking hence you can free up thread when there is no data to write.

I'm actually thinking about removing the writer thread completely. LMDB is single-writer and enforces that with a lock. In .NET you could just use Task.Run if you do not want to block the current thread and fire-and-forget a transaction.

What is your use case where this is important?

Background write thread is removed completely.
