- How to have AWS RDS synchronous read replication?
So the "synchronous" ability is there already, but I don't find any option to have a synchronous read only replica For my case, I want to have read replica to reduce read load on main DB, but data is very sensitive so cannot afford to read old data at all, any suggestion for my case here with AWS RDS service ? like making the "standby" being
- Synchronous database queries with Node. js - Stack Overflow
I have a Node js Express app that queries a MySQL db within the route and displays the result to the user My problem is how do I run the queries and block until both queries are done before redir
- Asynchronous vs synchronous execution. What is the difference?
Well, I don't think the answers explain the original motivation for the terminology But here's my take from what I came to know so far: synchronous - act based on a point of time, like the end of a timeout asynchronous - act based on an event happening, irrespective of time These terms make a lot of sense when put this way
- difference between Asynchronous and Synchronous in . net 4. 5
Checks of completed awaiters and a state machine are involved This makes some asynchronous operations take more time than the corresponding synchronous operation On the other hand, most operations suited for async-await are naturally asynchronous and there is some extra processing involved to make it look and feel synchronous In these cases
- How can I access indexedDB synchronously? - Stack Overflow
It's naturally going to be quite hacky, since browsers try to get you to avoid doing synchronous storage access, since it can be slow (i e up to tens of milliseconds - vs memory RAM access which is several orders of magnitude faster) and will cause the main thread to lag while the data is being fetched Here's what I think you'd need to do:
- webserver - What is the difference between asynchronous and synchronous . . .
If the synchronous means ping-pong of request-response in that order, that is what blocking also means: thread is blocked until the request-response operation cycle gets completed In turn, asynchronous differs from ping-pong order, and that's also what non-blocking means: requestor doesn't wait for the response, hence no thread is blocked
- Angular RxJS: synchronous observable - Stack Overflow
firstValueFrom(observable) is also not synchronous, because you have to await both call's, which means other resources can do stuff while waiting on the result – gangfish Commented Mar 27, 2023 at 15:03
- What is the difference between Asynchronous calls and Callbacks
Basically - if a callback does all it's work before returning to the caller, it's "synchronous" If it can return to the caller immediately after it's invoked - and the caller and the callback can work in parallel - then it's "asynchronous" The problem with synchronous callbacks is they can appear to "hang"
