Is there a way to use synchronized() with coroutines? I have a need for several short running coroutines/threads to synchronize access to another function that gets data. Synchronization is needed since the first call is over http then cached locally, to prevent redundant web requests.

import kotlinx.coroutines.sync.Mutex

private val lock = Mutex()
…
lock.withLock {
  // critical section
}

Thanks, will give that a try

You could load the required data with async, then keep the resulting Deferred. The result of the HTTP call will be cached for next function calls, requiring no synchronization

No the issue is when 2 calls happen at nearly the same time.

You could also use actors.
