pino-roll Is it based on main thread or sub-thread?

[jinxiaoman]

I just learned about him and it’s cool. Before, I created a sub-thread fs to write by myself. I would like to ask whether pino-roll is a sub-thread or the main thread. If it is the main thread, will there be any performance problems when writing a large number of logs?

pino-roll is a variant of transport. Transports mechanism ran on a worker thread by its nature, so for your question, No it doesn't run on the main thread (and that's a good thing)

[mcollina]

it can also run on the main thread if you want, you can just use it as a stream.
