I admit that I probably read into that based on the historical use of ThreadLocals to carry context in traditional ‘request is a thread’ systems. I think as Axel pointed out it is more explicit in the ’structured concurrency’ paper.
In Java the Thread has always carried context - it is used in security, logging, debugging, etc. The availability of millions of threads is not going to change that - as outlined in the first paper. Anyway, I am glad you found it interesting. > On Oct 1, 2022, at 9:33 AM, Juliusz Chroboczek <j...@irif.fr> wrote: > >> Very interesting article came out recently. >> https://www.infoq.com/articles/java-virtual-threads/ > > Interesting article, thanks for the pointer. > >> it has implications for the Go context discussion and the author makes >> a very good case as to why using the thread local to hold the >> context - rather than coloring every method in the chain is a better >> approach. > > I didn't read that in the article, but then I may be missing something. > My takeaway is that: > > - with M:N threds, one must be careful to not stash too much data in > thread local storage, since there may be large numbers of threads; > > - with M:N threads, there's no need to do use thread pools; in the > absence of thread pools, thread-local storage is more useful, since > there's no risk of leaking thread-local data to a different task. > > This implies to me that there is an interesting tradeoff, but does not > by itself argue against Go's design. > > -- Juliusz > > -- > You received this message because you are subscribed to the Google Groups > "golang-nuts" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to golang-nuts+unsubscr...@googlegroups.com. > To view this discussion on the web visit > https://groups.google.com/d/msgid/golang-nuts/87k05jpqae.fsf%40pirx.irif.fr. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
