Re: [go-nuts] sharded rw mutex approaches?

[Robert Engels]

I know some people are put off by stuff like this, but reading the Java JDK concurrent package provides a wealth of information- it is well documented and almost all are referenced implementations of academic papers. In this case, the Java concurrent hash map would be an applicable design.  You can see some of this - not nearly as good or complete - in my github.com/robaho/go-concurrency-test On Mar 14, 2025, at 12:17 AM, Jason E.

I can just take the hash value modulo a the size of a fixed set of locks... Thanks Robert. p.s. awl, thanks, yes... saw that. thank you.
